查询词典 biotite granite

The chemical composition of Pingyang gneissic granite with high contents of SiO〓, Na〓O, Sr and Ba was inherited and developed from that of mainly biotite gneiss through anatexis under the background of regional migmatisation, it might also be introduced the fluid material from deep.

平阳片麻状花岗岩的化学成分是在区域混合岩化对岩石成分总体改造趋势的背景下，在黑云斜长片麻岩成分的基础上，通过黑云斜长片麻岩的深熔以及可能的变质脱水反应流体和深部流体的加入演变而成，富SiO〓、Na〓O以及Sr和Ba。

One earlier variety of the granites, provisionally termedas Kushan Granite, is coarser-grained, often flesh-colored, and biotite-bearing,similar in character to the most frequently seen and widely distributed graniteof whole Fukien; the other, the Kueichi Granite, often intruding into the firstnamed, is colored by different shades of grey, mostly, fine-grained, and mia-rolitie, containing minor amount of hornblen...

从二者产生状态看来，彼此生成时间甚为接近，而同属於太平洋运动产物，分属早晚期活动。再根据前人各种地质文件，推论出福建各地普遍存在着相当於这两种侵入的花岗岩类岩石。因此，联系到福建后侏罗纪金属矿成矿作用的多次性可能。这在江西西华山已有发现。此后从多次性来研究后侏罗纪的炎成矿床的成矿作用，成为必要了。
