This meteorite was interacting with water on its parent asteroid while still in space. Contact with this extraterrestrial water has altered many of its silicate minerals to be hydrous phyllosilicates. The specimens reveal a dark black interior with many gray-white areas \u0026lt;1 mm, and rare small bright metal flecks. Most of he outer edges of the slices cut from this meteorite display a pristine fresh black fusion crust.\u003c\/p\u003e\n\u003cp\u003eI really enjoyed analyzing and classifying this meteorite. While it was perhaps the most difficult meteorite I have ever worked on, it was also the most rewarding. It pushed my boundaries on many levels and gave me a new appreciation for just how complex and enigmatic these aqueously altered chondrites realIy are. I don't think it would be an exaggeration to say that one could spend a lifetime studying just this one meteorite. My petrographic examination of this specimen with the microprobe's BSE imaging at the University of Colorado Boulder shows chondrules, chondrule fragments, tochilinite-cronstedtite intergrowths (TCIs), and Calcium aluminum-rich inclusions (CAIs) set in a fine-grained black matrix \u0026gt;50 vol%. Most chondrules are porphyritic type I with predominantly forsteritic olivine. A few type IIA chondrules were also observed. Most chondrules are altered and display fine-grained dust rims. Apparent mean chondrule diameter approximately 324±168 µm (n=20). Matrix olivines are fragmental and ferroan. Rare metal in matrix and chondrules are often enclosed by silicates or glass. TCIs are present throughout the matrix...(excerpt taken from the petrology section of the official Meteoritical Bulletin classification writeup, full writeup included below).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"375\" width=\"500\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1185\/2762\/files\/IMG_6574.jpg?v=1741898554\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat you get:\u003c\/strong\u003e 2.46g \u003cmeta charset=\"utf-8\"\u003eTinina 001, CM2 Carbonaceous Chondrite Meteorite slice as shown, membrane storage\/display box, \u0026amp; signed Certificate of Authenticity.\u003c\/p\u003e\n\u003cp\u003eWe offer a 100% no questions asked 30 day return policy. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003eSEE OFFICIAL METEORITICAL BULLETIN DATABASE ENTRY BELLOW\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003ctable class=\"tablefat\" cellspacing=\"0\" cellpadding=\"4\" id=\"maintable\" border=\"1\"\u003e\n\u003ccaption\u003e\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr valign=\"top\"\u003e\n\u003cth colspan=\"2\" class=\"insidehead\"\u003e\u003cspan\u003e\u003cb\u003eTinina 001\u003c\/b\u003e\u003c\/span\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd class=\"inside\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cbig\u003eBasic information\u003c\/big\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd class=\"inside\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003eName:\u003c\/b\u003e Tinina 001\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e     This is an OFFICIAL meteorite name.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003eAbbreviation:\u003c\/b\u003e There is no official abbreviation for this meteorite.\u003c\/span\u003e\u003cbr\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eObserved fall:\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003eNo\u003cbr\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eYear found:\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003e2023\u003cbr\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCountry:\u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003eLibya\u003cbr\u003e\u003cb\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cspan\u003eMass:\u003c\/span\u003e\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003e140 g\u003cbr\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd class=\"inside\"\u003e\u003cbig\u003eClassification\u003cbr\u003e  history:\u003c\/big\u003e\u003c\/td\u003e\n\u003ctd class=\"inside\"\u003e\n\u003ctable summary=\"used for layout\" cellspacing=\"0\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eRecommended:  \u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cb\u003eCM2\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003e  \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cbr\u003eThis is 1 of 655 approved meteorites classified as CM2.   \u003cbr\u003e\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd class=\"inside\"\u003e\u003cbig\u003eComments:\u003c\/big\u003e\u003c\/td\u003e\n\u003ctd class=\"inside\"\u003eApproved 23 Feb 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd class=\"inside\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cbig\u003e\u003cspan\u003eWriteup\u003c\/span\u003e\u003c\/big\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd class=\"inside\"\u003e\n\u003cdiv\u003e\n\u003cu\u003e\u003c\/u\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"writeup\"\u003e\n\u003cbig\u003e\u003cu\u003eWriteup from MB 114:\u003c\/u\u003e\u003c\/big\u003e\u003cbr\u003e\n\u003cdiv\u003e\n\u003cp class=\"MBNormal\"\u003e\u003cstrong\u003eTinina 001\u003c\/strong\u003e        31.41281°N, 13.69218°E\u003c\/p\u003e\n\u003cp class=\"MBIndent\"\u003eSawfajjin, Libya\u003c\/p\u003e\n\u003cp class=\"MBIndent\"\u003ePurchased: 2023 Aug\u003c\/p\u003e\n\u003cp class=\"MBIndent\"\u003eClassification: Carbonaceous chondrite (CM2)\u003c\/p\u003e\n\u003cp class=\"MBNormal\"\u003e\u003cstrong\u003eHistory\u003c\/strong\u003e: Purchased by Isaac Schroeder in August, 2023, from a meteorite hunter in Libya.\u003c\/p\u003e\n\u003cp class=\"MBNormal\"\u003e\u003cstrong\u003ePhysical characteristics\u003c\/strong\u003e: A single 140 g stone with scoriaceous black fusion crust covering the exterior.
