The mineralogy — olivine, low-calcium pyroxene, pigeonite, augite, and calcic plagioclase (up to An97) — is textbook lunar highlands material, and the rock is heavily shocked, with plagioclase partially transformed into maskelynite, a high-pressure mineral that only forms under intense impact conditions. Researchers have noted a possible pairing relationship with the NWA 8046 clan of lunar meteorites.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\"\u003e\u003cstrong\u003eClassification:\u003c\/strong\u003e Lunar meteorite, feldspathic breccia\u003cbr\u003e\u003cstrong\u003eFound:\u003c\/strong\u003e Algeria (purchased March 2021)\u003cbr\u003e\u003cstrong\u003eTKW:\u003c\/strong\u003e 712g\u003c\/p\u003e","brand":"Rad Man Minerals","offers":[{"title":"Default Title","offer_id":54326776955164,"sku":null,"price":65.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/5524\/1500\/files\/P7190211.jpg?v=1784589998","url":"https:\/\/radmanminerals.com\/products\/nwa-13937-lunar-meteorite-feldspathic-breccia-0-46g","provider":"Rad Man Minerals","version":"1.0","type":"link"}
