The polished face shows the dark green-grey, finely crystalline interior of a Martian igneous rock.\u003c\/p\u003e\n\u003cp\u003eNWA 18168 is a Martian Shergottite found in Western Sahara. Shergottites are igneous rocks that crystallised from basaltic magma on Mars, and they are the most common type of Martian meteorite. Like every Martian meteorite, it was blasted from the planet's surface by a large impact and spent time in space before falling to Earth.\u003c\/p\u003e\n\u003cp\u003eThe link between these meteorites and Mars is well established. Gases trapped in shock-melted glass within some shergottites match the composition of the Martian atmosphere measured by NASA's Viking landers, and the oxygen isotope compositions of Martian meteorites set them apart from rocks from Earth, the Moon and the asteroids.\u003c\/p\u003e\n\u003cp\u003eMartian meteorites make up well under one per cent of all classified meteorites, which makes even small pieces a special addition to a collection. Each slice is presented in a display box with its specimen label.\u003c\/p\u003e","brand":"OuterSpacer Meteorites","offers":[{"title":"Default Title","offer_id":57869693878598,"sku":"OSM-22\/02","price":217.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/0518\/8678\/files\/20260114_153847-2.jpg?v=1794477046","url":"https:\/\/outerspacer.com\/products\/nwa-18168-martian-shergottite-slice-3g-western-sahara","provider":"OuterSpacer Meteorites","version":"1.0","type":"link"}
