Errachidia 004 was recovered from a newly recognized dense collection area in the Moroccan Sahara in 2020, and classified as a \u003cstrong\u003ewinonaite\u003c\/strong\u003e — one of the rarest achondrite classes known, with fewer than 65 examples recovered worldwide.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\"\u003eWinonaites are primitive achondrites: material that started out chondritic but underwent partial melting and incomplete differentiation before that process was interrupted, preserving a transitional snapshot between unmelted asteroids and their fully differentiated, iron-cored cousins. Errachidia 004 is especially significant even within this rare group — it contains \u003cstrong\u003etwo distinct lithologies\u003c\/strong\u003e in the same fall: a metal-poor lithology (forsterite, enstatite, augite, sodic plagioclase) and a metal-rich lithology with substantial kamacite and taenite showing Widmanstätten patterning. Researchers studying the meteorite suggest it may represent transitional material between the winonaite class and the silicate-bearing IAB iron complex — evidence of a \"rubble pile\" parent body where fragments from very different depths were mixed and reassembled before final consolidation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\"\u003eWith a total recovered mass of only about 2.6 kg split across two lithologies, well-documented Errachidia 004 material — particularly pieces that clearly show the high-metal lithology's Widmanstätten structure — is genuinely scarce.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\"\u003e\u003cstrong\u003eClassification:\u003c\/strong\u003e Primitive achondrite (Winonaite, dual-lithology\/anomalous)\u003cbr\u003e\u003cstrong\u003eFound:\u003c\/strong\u003e Errachidia region, Morocco, 2020\u003cbr\u003e\u003cstrong\u003eTKW:\u003c\/strong\u003e ~2.64 kg\u003c\/p\u003e","brand":"Rad Man Minerals","offers":[{"title":"Default Title","offer_id":54326780887324,"sku":null,"price":50.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/5524\/1500\/files\/P7190218.jpg?v=1784590590","url":"https:\/\/radmanminerals.com\/products\/errachidia-004-winonaite-primitive-achondrite-0-96-grams","provider":"Rad Man Minerals","version":"1.0","type":"link"}
