Ez a bazalt egy \u00faj oszt\u00e1ly\u00e1t jelenti”- mondta Li Csun-laj, a Nature c\u00edm\u0171 tudom\u00e1nyos foly\u00f3iratban megjelent tanulm\u00e1ny vezet\u0151szerz\u0151je, hozz\u00e1t\u00e9ve, hogy az \u00fajonnan azonos\u00edtott bazaltmint\u00e1k k\u00fcl\u00f6nb\u00f6znek a kor\u00e1bbi holdmisszi\u00f3k \u00e1ltal gy\u0171jt\u00f6tt mint\u00e1kt\u00f3l.

A Csang’o-5 mintegy 1,7 kilogramm k\u0151zetet gy\u0171jt\u00f6tt a Holdon 2020 december\u00e9ben. N\u00e9gy \u00e9vtizede ez volt az els\u0151 minta, amely az \u00e9gitestr\u0151l lejutott a F\u00f6ldre. K\u00edna a k\u0151zetmint\u00e1kb\u00f3l 17 grammnyit \u00e1tadott 13 m\u00e1sik int\u00e9zm\u00e9nynek tudom\u00e1nyos kutat\u00e1s c\u00e9lj\u00e1ra.<\/p>\n\n\n\n

Ausztr\u00e1l kutat\u00f3k vizsg\u00e1lata meg\u00e1llap\u00edtotta, hogy a mint\u00e1k nagyj\u00e1b\u00f3l k\u00e9tmilli\u00e1rd \u00e9vesek, teh\u00e1t mintegy egymilli\u00e1rd \u00e9vvel fiatalabbak, mint a kor\u00e1bban F\u00f6ldre hozott k\u0151zetek.<\/p>\n\n\n\n

Ez azt\u00a0jelenti, hogy a\u00a0vulkanikus tev\u00e9kenys\u00e9g\u00a0a\u00a0Holdon\u00a0800-900\u00a0milli\u00f3 \u00e9vvel hosszabb idej\u0171\u00a0volt a\u00a0kor\u00e1bban v\u00e9ltn\u00e9l.<\/p>\n\n\n\n
