Many of the chondrules are armored (surrounded by metal). As of this listing, only ten L3.10 chondrites have been classified. This is a rare difficult to find unequilibrated L3.10 chondrite with a low 386.2 gram total known weight (TKW). Unequilibrated subtypes of 3.00 to 3.15 are barely altered from their original accretion and are quite rare. They require substantially more analysis points for the classification, as the exact extent of equilibration is established by averaging the wt% of Cr2O3 against its standard deviation over many analysis points in the ferroan olivine of type II chondrules.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1185\/2762\/files\/Cr2O3_NWA-7980_LL310_MEAN-STDEV_Plot_600x600.jpg?v=1794519934\" alt=\"NWA 7980 L 3.10 unequilibrated ordinary chondrite rare meteorite Top Meteorite\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eWhat you get:\u003c\/strong\u003e\u003cspan\u003e 26.4\u003c\/span\u003eg L3.10 Ordinary chondrite meteorite as shown, and signed Certificate of Authenticity.\u003c\/p\u003e\n\u003cdiv\u003eWe offer a 100% no questions asked 30 day return policy.  \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp style=\"text-align: center;\"\u003eNorthwest Africa 7980\u003c\/p\u003e\n\u003cdiv class=\"alert\"\u003e\n\u003cp\u003e\u003cstrong\u003eStatus: \u003c\/strong\u003eOfficial\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"container mb-4\"\u003e\n\u003ctable class=\"text-table th-left\" style=\"width: 100.049%; height: 1641.22px;\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"row\" style=\"height: 137.2px;\"\u003e\n\u003cth class=\"col-12 col-md-3 col-lg-2\" style=\"width: 25.0122%; height: 137.2px;\"\u003eBasic information\u003c\/th\u003e\n\u003ctd class=\"col-12 col-md-9 col-lg-10\" style=\"width: 71.6137%; height: 137.2px;\"\u003e\n\u003cstrong\u003eName:\u003c\/strong\u003e Northwest Africa 7980 This is an OFFICIAL meteorite name.\u003cbr\u003e\u003cstrong\u003eAbbreviation:\u003c\/strong\u003e NWA 7980\u003cbr\u003e\u003cstrong\u003eObserved fall: \u003c\/strong\u003eNo\u003cbr\u003e\u003cstrong\u003eYear found: \u003c\/strong\u003e2013\u003cbr\u003e\u003cstrong\u003eCountry: \u003c\/strong\u003eMorocco\u003cbr\u003e\u003cstrong\u003eMass: \u003c\/strong\u003e386g\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row\" style=\"height: 185.2px;\"\u003e\n\u003cth class=\"col-12 col-md-3 col-lg-2\" style=\"width: 25.0122%; height: 185.2px;\"\u003eClassification history:\u003c\/th\u003e\n\u003ctd class=\"col-12 col-md-9 col-lg-10\" style=\"width: 71.6137%; height: 185.2px;\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMeteoritical Bulletin, \u003ca href=\"https:\/\/www.lpi.usra.edu\/meteor\/docs\/mb102.pdf\" title=\"Meteoritical Bulletin, no. 102, MAPS 50, 1662, September 2015\"\u003eMB 102\u003c\/a\u003e (2013): \u003c\/strong\u003eL3.10\u003cbr\u003e\u003cstrong\u003eRecommended:\u003c\/strong\u003e L3.10    \u003cbr\u003e\u003cbr\u003eThis is 1 of 10 approved meteorites classified as L3.10.    \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row\" style=\"height: 19.6px;\"\u003e\n\u003cth class=\"col-12 col-md-3 col-lg-2\" style=\"width: 25.0122%; height: 19.6px;\"\u003eComments:\u003c\/th\u003e\n\u003ctd class=\"col-12 col-md-9 col-lg-10\" style=\"width: 71.6137%; height: 19.6px;\"\u003eApproved 13 Sep 2013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row\" style=\"height: 820.425px;\"\u003e\n\u003cth class=\"col-12 col-md-3 col-lg-2\" style=\"width: 25.0122%; height: 820.425px;\"\u003eWriteup \u003c\/th\u003e\n\u003ctd class=\"col-12 col-md-9 col-lg-10\" id=\"writeups\" style=\"width: 71.6137%; height: 820.425px;\"\u003eWriteup from \u003ca href=\"https:\/\/www.lpi.usra.edu\/meteor\/docs\/mb102.pdf\"\u003eMB 102:\u003c\/a\u003e\u003cbr\u003e\n\u003cdiv class=\"writeup\"\u003e\n\u003cp class=\"MBNormal\"\u003e\u003cstrong\u003eNorthwest Africa 7980\u003c\/strong\u003e (NWA 7980)\u003c\/p\u003e\n\u003cp class=\"MBIndent\"\u003eMorocco\u003c\/p\u003e\n\u003cp class=\"MBIndent\"\u003ePurchased: 2013\u003c\/p\u003e\n\u003cp class=\"MBIndent\"\u003eClassification: Ordinary chondrite (L3.10)\u003c\/p\u003e\n\u003cp class=\"MBNormal\"\u003e\u003cstrong\u003eHistory\u003c\/strong\u003e: Purchased by Brahim Tahiri from a Moroccan hunter and sent to Sean Tutorow for classification, 2012.\u003c\/p\u003e\n\u003cp class=\"MBNormal\"\u003e\u003cstrong\u003ePhysical characteristics\u003c\/strong\u003e: Thirty two matching fragments, dark weathered fusion crust, broken surface reveals many densely packed orange-brown chondrules of variable size, set in darker matrix.\u003c\/p\u003e\n\u003cp class=\"MBNormal\"\u003e\u003cstrong\u003ePetrography\u003c\/strong\u003e: (C.
