pyrolite
解釋
地幔巖-
Based on the petrological, petrochemical and geochemical analyses about these rocks, it is concluded in this paper that the xenoliths were originated from the upper mantle, and comprised of both primitive pyrolite and the infusible solid residual of the upper pyrolite while the basaltic magma was melted out of it, which were brought up to the earth ' s surface via o1carnc eruption
根據其巖石學、巖石化學及地球化學特徵分析，包體來源於上地幔，其成因既有原始地幔巖，亦有上地幔巖經部分熔融出玄武巖漿后的難熔固相殘留物，被火山噴發攜帶至地表。 -
Ultramafic rock fragments, which almost is altered to ophite, distributed in structural zone and displayed structural lens. so far, 9 fragments were discovered and mapped in nujinshan and bujing area ultramafic rock can be divided two kinds according to it ' s geochemical characteristics. one can be correlated with metaperidotite, which represented residual part that primary pyrolite underwent moderate partial melting, from some representative ophiolite melange in the world
按超鎂鐵巖類的地球化學特徵可將其劃分為兩類：一類具有較高而穩定的mgo 、較低的al _ 2o _ 3 、極低的cao ， m f值為8 . 0 ? 8 . 4 ，按標準礦物組合進行分類可定為方輝橄欖巖，且均為fa _ （ 100 ） 、 en _ （ 100 ）的鎂質端元組分；可與世界上一些典型的蛇綠巖套中變質橄欖巖進行對比，代表了原始地幔中等部分熔融作用后殘余物。
