Hello All, I've been asked to tell you that there are new pictures up on Mbark's page - here's the url:
http://www.flickr.com/photos/[EMAIL PROTECTED]/ I'd just like to add that, at the moment, Mbark's posted prices are ~1/2 that of what other dealers are asking - for nearly identical, if not more weathered material...$350-500/g for a monzogabbro when more typical lunars go for ~$600/g at low prices is simply cheap... Contact Mbark Ait Lkaid at [EMAIL PROTECTED] for more information. Original message with weights below: --- Hello All, I'd like to introduce myself. My name is Mbark Ait Lkaid, and I am a well-known meteorite dealer from Rissani, Morocco. I was the source of many of the important meteorites that you have come to see grace the meteorite market over the past several months, namely the renowned NWA 4483, and today I'd like to announce that I have another very special meteorite available for collectors: the Lunar Monzogabbro NWA 4734. I own the main mass, and, am making it available to all of you on a first-come, first-serve basis. Here's a copy of the scientific abstract: Proposed Name NWA 4734 Geographic Coordinates: Undisclosed. Erfoud, Morocco Find : October, 2006 - Show quoted text - Major classification group) Achondrite (Lunar monzogabbro) History: bought from nomads in Erfoud ( Morocco ) in October 2006 and February 2007. Physical characteristics: One complete crusted stone freshly broken into several pieces for a TKW of 1439 g . Dull black/brown fusion crust. It is a light gray, coarse grained, pristine magmatic rock consisting of millimetric phenocrysts mainly of pyroxene and plagioclase. The few patches where crust is missing are light tanned. Petrography: A. Jambon, O. Boudouma and D. Badia. UPVI . The texture is best described as shergottitic like. Pyroxene are highly fractured while plagioclase laths, partly transformed to maskelynite, are only affected by a small number of fractures. Silica and silica-feldspar glass are minor components. A few impact melt patches underline the similarity with shergottites further. Ilmenite, baddeleyite, zirconolite, tranquilityite, pyrrhotite and metal. Fayalite associated with silica probably results from the dissociation of iron rich pyroxene. Minor terrestrial alteration. Mode (vol %): Cpx 50, Plagioclase + Kspar 32, silica + glass 7.5, opaques (ilmenite, Ti-magnetite, pyrrhotite) + fayalite 7, voids + fractures 3. Geochemistry: Mineralogy by EMP and SEM.(Trace -ICP-MS- and major -ICP-AES- element analyses, J-A Barrat UBO). Pyroxene exhibit a complex zoning from En65Fs21Wo13 to En2Fs83Wo15 with a FeO/MnO of 78 on the average. A few compositions correspond to pyroxferroite. Plagioclase is normally zoned from An 91 to An 75 with a sharp rim. Average composition An 89. Fayalite (Fa 80 to 95). Chondrite normalized REE pattern with an enrichment of 53 (La) to 40 (Yb). Trace element pattern with negative anomalies of Sr and Eu. Interstitial glass high in silica (75%) containing microcrysts of K feldspar with a significant celsian component. Classification: According to the grain size, the texture, the plagioclase composition, the core composition of pyroxenes, the FeO/MnO ratio in pyroxene and the chemical identity with lunar basalts, it is classified as a highly shocked lunar gabbro (Mare basalt). Type specimens: A total of 20 g of sample and one polished section is on deposit at UPVI. Stefan Ralew, Siriusstrasse 19, 12524 Berlin, Germany : 19.6g, 14.1g,10.8g Aziz Habibi, Palm's hotel, Erfoud, Morocco : 409g, 68 g . Mbarek Ait Elkaid, Rissani , Morocco 895g (one large piece and about ten subsidiary pieces and a few smaller fragments). ----- Here is a list of available specimens: 1_____443.2gr 2_____202 gr 3_____49.1gr 4_____46.1gr 5_____32.7gr 6_____24.8gr 7_____22.9gr 8_____12.6gr 9_____11gr 10____8.3gr 11____12.6gr (small fragments) Here are pictures of all of the specimens: http://www.flickr.com/photos/[EMAIL PROTECTED]/ For prices, email: [EMAIL PROTECTED] Kind Regards. ______________________________________________ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
