橄榄岩与榴辉岩中的一种金属合金

A metallic alloy from peridotite and eclogite

对江苏东海橄榄岩与榴辉岩中部分矿物的初步测试分析 ,发现其中存在一种金属矿物。其矿物结构与镍纹石近似。推测该矿物为具地幔特征的铁镁质残留物。

Preliminary process and analyses of the peridotite and eclogite from Donghai, Jiangsu Province, show that there is a metallic alloy in these rocks. Their structure is similar to that of taenite. The occurrence of the alloy suggests that it is the mafic residue from the mantle materials.
