kreep

1. KREEP rocks

KREEP岩

2. KREEP rocks with high contents of K, REE and P were first recognized in Apollo 12 samples, and confirmed later that there were KREEP rock fragments in all of Apollo samples particularly in Apollo-12 and 14 samples.

克里普岩(KREEP)最早发现于Apollo-12样品,后来在所有返月样品中都发现3克里普岩碎片,尤其以Apollo-12和Apollo-14着陆点样品中最多,因其富含元素K,REE和P而被称之为KREEP.

3. KREEP rocks formed at the boundary of lunar crust and mantle, and natural radioactive thorium is one of the elements to demonstrate KRREP rocks distribution.

月球KREEP岩石形成于壳幔的分界层中,天然放射性元素Th是指示KREEP岩分布的主要元素之一。

4. Lunar Prospector revealed that the highest concentrations of KREEP occur in the Oceanus Procellarum, although the reason for this unusual distribution is not clear.

月球探勘者号显示，最高的KREEP浓度出现于暴风海中，不过，如此不寻常的分布原因还不清楚。
