【#每日跟讀單元 701】南非的鑽石內發現來自地函的神秘礦物
摘要:
A single grain of rock lodged in a diamond contains a never-before-found mineral. And that newfound substance could reveal unusual chemical reactions unfolding in the depths of the mantle, the layer of Earth that lies between the planet’s crust and outer core. The entire mantle is about 1,802 miles (2,900 km) thick.
包裹在一塊鑽石內的小晶粒,含有一種此前從未在鑽石內發現的礦物。這項新發現有望揭示地函深處發生的不尋常化學反應,地球地函位在行星地殼與外地核之間。地球地函的總厚度約1802英里(2900公里)。
