[meteorite-list] Marginally Off-Topic; Impact Fractured Fossils
I'm intrigued by the physical tell-tales of impact events. Things like tektites, spherical glass or iron-nickel droplets all have a certain level of 'intuitive-simplicity'. Shatter-cones seem to reflect a general direction of energy propagation, with diffraction and redirection of wave as the advancing pressure encounters substances of different compressibility and susceptibility to micro fracture as the compressive and rarefaction regions proceed. (My presumed understanding may be way off base, but these items at least seem to make sense.) Fractured Belemnites really puzzle me. It seems countless numbers of these skeletal elements from ancient ancestors of today's squids were lying about when the Ries crater was created. Is there any discernible relationship between the direction of energy propagation and the planes of fracture? I have seen numerous examples of rocky matrix with multiple fractured belemnites embedded, each with its own set of generally parallel fractures, and no two items sharing a major horizon for cleavages. This arrangement can be seen in the current Ebay item # 321365886158. I have searched the web in vain for any description of the ways in which Belemnites may have captured and directed the energy, or how the structure of the belemnite itself would have predisposed it to these fracture patterns. I have tried stressing in different ways whole belemnite fossils (admittedly, a few million years of aging different from the conditions that may have prevailed 'back then'.) Nothing I can learn of says there is a diagonal structural weakness, yet many fractured specimens exhibit parallel, but oblique, or diagonal cleavages. Can anyone point me to an explanation, on the web, or in a book? Thanks much! __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] LOVINA
Hi Paul, Sounds like an interesting vacation. On February 14th I posted detailed correspondence to the list concerning the publication of what was then an upcoming LPSC abstract on Lovina which I had instigated with Qingzhu Yin of University of California Davis. Here is the link: http://www.hou.usra.edu/meetings/lpsc2014/pdf/1434.pdf It now seems clear Lovina is terrestrial. At the same time, in the words of several meteoriticists, Lovina is far more rare than a typical iron meteorite." Given that its elemental signature—including elemental ratios—so closely approximates that of an iron meteorite, Lovina is a fascinating link between the terrestrial and extraterrestrial. In addition, given its ziggurat (pyramidal) structure, Lovina is the single finest specimen of awaruite known, and your dad would do quite should he find more.

Ash et al. http://www.hou.usra.edu/meetings/lpsc2014/pdf/1434.pdf The conclusion is that it is almost impossible for LOVINA to have spent any time in space.
