Re: [meteorite-list] The EL3/Aubrite/whatever - Why FOSSIL?
Hi Dean, Yes this is very confusing and unscientific. As you deal in fossils, I think you have a gut appreciation of what a fossil is (rare occurence, once living, formed in a long process, from sediment deposition) and what it is not (an inorganic rock). For example, Adam Hupe has been confusing the term relic with relict in his posts (spell check I am sure), which is basically the same very dubious leap of definition. The fossiliferous nature can be better explained by: Paleoölogists argue that the rare petrified relict ooliths formed during sediment deposition in an old soggy-bottomed Sahara creek from promiscuous remains of pyroxene-based creatures (with a DNA paucity). Fossil is used in quotes to distinguish lithified alien life forms vs. common DNA-coded carbon life forms. Aubrite is a golden glowing substance developed by The Authentic Fossil (trademarked logo) company to be used on watch dials in the Relic product line in place of radium. http://en.wikipedia.org/wiki/Fossil,_Inc. Alternately, Fossil (TM) may be written for marketing purposes, much like Amgala, Inc. Interestingly, the MetSoc NomCom approved a whole series of Numbers starting with AL HAGGOUNIA 001. Wonder if there was more to this than meets the eye? Why a 001 before any mention of a 002? Is this somewhat of a departure for the NomCom, and the series have been used to designate numbers either unassignable locations in dense regions (e.g., NWA), or, regions with too few place names to go around (e.g. Oman), or the new category of Relict meteorites (e.g., Österplana) -like those recovered in some sediments known to yield meteorites. Could the latter have influenced putting the premature numbering system in place for Al Haggounia? LOFL, Doug - Original Message - From: Sterling K.

Hi, Dean, I'm sure someone will have the paper and a mountain of details, but the short-and-simple is: it sat in a lake bottom which turned to a swamp which turned to a pan and so forth as the Sahara dried out and went from a wooded grassland with lakes and rivers to a pocket edition of the Inferno. A fossil is when other minerals, by aqueous alteration, replace the original (usually) organic materials. In a meteorite, this is the extreme form of weathering and terrestrialization. The term fossil fits what happened to it, although people leave those quotes around so you'll know the term is by analogy to organic fossils. A lot of strange claims have been made about its age because many mistakingly believe the Sahara is an ancient desert. No, it was a pretty nice neighborhood until the last ice age glaciation started to fail. Rain started getting scarce in the eastern Sahara about 14,000 years ago and in the western Sahara about 12,000 years ago. Desertification is a long process. The NE Sahara was home to prosperous Greek states until about 2200 years ago, and only 2000 years ago the NW Sahara was one of the great Breadbaskets of the Roman Empire and remained so until only 1600 years ago. Not much like Iowa now, I understand... Hope that helps. Sterling K.

The chrondrules are real chrondrules and not a replaced with stone chrondrule.
Re: [meteorite-list] The EL3/Aubrite/whatever - Why FOSSIL?
It seems to me that there are at least four or five different things that people may be trying to describe using various terms, including fossil and paleo. 1) The original minerals in a meteorite may be partially or completely converted to terrestrial minerals on earth. 2) During alteration and weathering, original textures may or may not be pseudomorphed by secondary minerals. 3) A meteorite may have a very old terrestrial age. 4) A meteorite may become buried in terrestrial sediments. 5) The sediments in which a meteorite is buried may become lithified. There are lots of combinations possible among the above. Brunflo and Osterplana meteorites have been buried, lithified, pseudomorphed, and have extremely high terrestrial ages. The (as yet unofficial) Morokweng stone has been buried, lithified, has an old age, but retains much of the original mineralogy. The Eltanin meteorite also retains much of its mineralogy, is old, but was deeply buried in unconsolidated sediment, not rock. Highly oxidized iron meteorites may consist entirely of terrestrial minerals, with no pseudomorphing, no burial in sediment, and young ages. Some antarctic meteorites have terrestrial ages of several million years, with no burial in sediment at all, and retain their mineralogy. In this context, what do the various terms that are being tossed about mean? Paleo means old or ancient. But how old does a meteorite have to be to get the moniker paleometeorite? I don't know. Is 10,000 years enough, as in the term paleolithic? If so, lots of Antarctic meteorites are paleometeorites, as are quite a number of hot desert meteorites. I think that to be useful, this term needs to only refer to terrestrial age, and not be linked to burial or weathering. The term relict meteorite is fairly well-defined by the Nomenclature Committee in its Guidelines for Meteorite Nomenclature: ...highly altered materials that may have a meteoritic origin [are] designated relict meteorites, which are dominantly (95%) composed of secondary minerals formed on the body on which the object was found. Examples of such material may include some types of meteorite shale, fossil meteorites, and fusion crust. Note that this term is independent of an object's age or whether it was buried. Fossil meteorite, used above, has never really been defined, but is has been mostly applied to things like Brunflo and Osterplana, where traces of highly altered meteorites are found in rocks and ancient sediments. However, it has also been used as a synonym for highly weathered meteorites found at the surface of the earth. I think that it may be possible to come up with a rigorous definition, but I suspect that if I did it, people would object. To be useful, I would suggest that this term should be defined to reflect incorporation into a rock or ancient sediment, and be independent of the degree of alteration or mineral replacement. Bottom line: I think a set of useful terms could be defined, but for now the only one with a rigorous meaning is relict meteorite. The others are basically fluff. jeff At 11:18 PM 12/1/2007, dean bessey wrote: I dont want to get involved in the thread about what the classification is (I will be pretty happy no matter what the proposed options are) but can somebody explain to me why its called a Fossil meteorite?

Re: [meteorite-list] The EL3/Aubrite/whatever - Why FOSSIL?
Hi All, Here's an interesting link to a scientific draft about fossil meteorites: http://epsc.wustl.edu/~visscher/research/fossil_files/frame.htm (It works best for IE, and doesn't display correctly in Firefox, for some obscure reasons.) The author tries to come up with a definition for fossil meteorite, following the suggestions of Schmitz B. and Tassarini M. (2001) Fossil Meteorites in Accretion of Extraterrestrial Matter Throughout Earth's History. Kluwer Academic, New York, 319-331. What is a fossil meteorite? - Meteorite with ancient terrestrial age - Buried in sediment after fall event - Incorporated into geologic record At least the second point seems to be true for the meteorite in question as I have seen fragments imbedded into sediment... It will be interesting to see what terrestrial age will be determined for this material, in the end.

Re: [meteorite-list] Why Fossil?
Dean, since the loose definition of fossil is any evidence of former life, obviously a meteorite, well, most;-), cannot be a fossil. Paleo, or old, is the better term, and in the case in discussion represents a meteorite that has fallen in past times to the extent of having been incorporated into what became a geologic formation and, in some cases, weathered out again. Your confusion seems to be between fossilization, or the preservation of any evidence of former life (like a basically unaltered mammoth tusk in the Artic), and petrification, or the replacement or pereservation of material by the introduction of silica, like petrified wood. The interesting thing, is that in well preserved petrified wood the cellulose can remain. The silica can be dissolved out and the cellulose structure captured and studied, even to the extent of taking biologic stains. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Fossil as a 17th century term for excavated meteorite?
Hi list, Can anyone tell me when the word fossil was first used to describe meteorites of this kind? The use of the term to refer to obtaining anything by digging comes from the early 17th century, its use with chiefly organic remains a century later (1736). I was wondering whether the word, in the field of meteorites, had come to us from before 1736.

Re: [meteorite-list] Fossil as a 17th century term for excavatedmeteorite?
I can't answer when, but I do think that using fossil as an adjective applied to ancient meteorites is perfectly acceptable. In geology (and other sciences) it usually means anything preserved from an earlier geologic age, not necessarily something living. Fossil meteorite is as valid as fossil water. It is when using fossil as a noun that you would be on thinner ice, since that seems reserved for a remnant of an organism.

Some of you who are familiar with the Earth Impact Database already know about the craters listed but I found this neat little link on Answers.com that has a plethora of information on impact craters that's not in the database. And it's not just craters on earth either. There's links to info about craters on just about every other planet in our solar system and what impact list would be complete without photos of our nearest celestial body the moon.

[meteorite-list] magnetic meteorites
Hi List, I've read somewhere that it is possible for a meteorite to be magnetic. Reading that made me believe someone has discovered such a meteorite(s). Anyone out there on the List want to volunteer information and/or maybe some pictures (or a link to some pictures) of such an iron? Let me guess this first, mostly kamacite, right? If you have pictures, besides wanting to confirm my guess, I am interested in seeing the exterior, as in flow features and fusion crust. I would also be interested in knowing just how magnetic it is.

Re: [meteorite-list] magnetic meteorites
Hello Mike, ~92% of all meteorites are magnetic; all irons, all stony irons, and nearly all stones are magnetic. The only meteorites that are not magnetic would be the HED's (some of these are slightly magentic), as well as Aubrites (though some of these contain iron as well), planetary meteorites (oftentimes *slightly* attracted to a neodymium magnet, though one should never poke such meteorites with a magnet), and Rumuruti chondrites (in this case, because most of the iron is contained within iron sulfide, and is thus non-magnetic). Depending on the stone, a few carbonaceous meteorites are lightly magnetic, but in general, they tend to be magnetic as well. Almost all meteorites are magnetic...I don't know where you heard otherwise, but...yeah.

Hi Michael, Magnetic can mean more than one thing: 1.of or pertaining to a magnet or magnetism. 2.having the properties of a magnet. 3.capable of being magnetized or attracted by a magnet. 4.pertaining to the magnetic field of the earth: the magnetic equator. 5.exerting a strong attractive power or charm: a magnetic personality. 6.noting or pertaining to various bearings and measurements as indicated by a magnetic compass: magnetic amplitude; magnetic course; magnetic meridian. The definition pertaining to meteorites is #3 not #2. Best, ken Michael Murray wrote: Hi List, I've read somewhere that it is possible for a meteorite to be magnetic.

Re: [meteorite-list] magnetic meteorites
It is my understanding that most iron objects are susceptible to being magnitized, turned into magnets, if exposed to a strong magnetic field. So if a meteorite containing iron is exposed to strong ENOUGH magnets for long ENOUGH [note the qualifying capitalization], under the RIGHT circunstances it would not be impossible for SOME to become magnets.

Hi Ken, Jerry, List, I have seen pieces of man-made iron and pieces of magnetite become slightly magnetic after being exposed to the supermagnet I use to hunt with.

Message: 1 Hi list, Can anyone tell me when the word fossil was first used to describe meteorites of this kind? The use of the term to refer to obtaining anything by digging comes from the early 17th century, its use with chiefly organic remains a century later (1736). I was wondering whether the word, in the field of meteorites, had come to us from before 1736. Fossil: 1619, obtained by digging (adj.), from Fr. fossile, from L. fossilis dug up, from fossus, pp. of fodere to dig, from PIE base *bhedh- to dig, pierce. http://www.etymonline.com/index.php?search=fossilsearchmode=none Regards, Chris On Dec 2, 2007 5:48 PM, Chauncey Walden [EMAIL PROTECTED] wrote: Dean, since the loose definition of fossil is any evidence of former life, obviously a meteorite, well, most;-), cannot be a fossil. Paleo, or old, is the better term, and in the case in discussion represents a meteorite that has fallen in past times to the extent of having been incorporated into what became a geologic formation and, in some cases, weathered out again. Your confusion seems to be between fossilization, or the preservation of any evidence of former life (like a basically unaltered mammoth tusk in the Artic), and petrification, or the replacement or pereservation of material by the introduction of silica, like petrified wood. The interesting thing, is that in well preserved petrified wood the cellulose can remain. The silica can be dissolved out and the cellulose structure captured and studied, even to the extent of taking biologic stains. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list Content-Transfer-Encoding: 7bit From: Chris Peterson [EMAIL PROTECTED] Precedence: list MIME-Version: 1.0 To: meteorite-list@meteoritecentral.com References: [EMAIL PROTECTED] Date: Sun, 2 Dec 2007 12:11:53 -0700 Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; format=flowed; charset=iso-8859-1; reply-type=original Subject: Re: [meteorite-list] Fossil as a 17th century term for excavatedmeteorite?

In geology (and other sciences) it usually means anything preserved from an earlier geologic age, not necessarily something living. Fossil meteorite is as valid as fossil water. It is when using fossil as a noun that you would be on thinner ice, since that seems reserved for a remnant of an organism.

[meteorite-list] Magnetic Meteorites?
I am new to the list. I've been reading the list for about a month now. I just wanted to weigh in on the magnetic meteorite. I am a retired Electronics Engineer, so this is somewhat in my field of expertise. From what I know, when you say all meteorites are magnetic, what you mean is the meteorites are attracted to a magnet. Under the right conditions any meteorite containing Iron can be made magnetic by stroking the meteorite repeatedly in the same direction, or alternately, putting the meteorite in the center of a large coil of wire and passing a DC voltage thru the coil. I have just begun to collect meteorites Texas meteorites in the range of 1 to 3 grams. I bow to those with more knowledge about meteorite for the rest of the comments. I hope this helps. de Pete __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
