查询词典 surrounding rock

In this research project, we have got a series conclusions:(1) there is no excess argon in the high-pressure white micas being in the orthogneiss;(2) The distribution of excess argon in eclogite is positive correlative with the ratio of Mg/, but negative with the ratio of Na/;(3) The in-situ analyses by using the method of laser probe 39Ar-40Ar show that the age radius from central to margin in a single grain of high-pressure white mica in eclogite;(4) There is no any evidence to prove that the excess argon in eclogite comes from fluid;(5) The excess argon in eclogite inherited from primitive rock during high-ultra high pressure metamorphism;(6) There is no excess argon in the eclogite when its surrounding rock is carbonate.

本项目用综合手段，研究了高压白云母中过剩氩的来源、赋存、分布与岩性、产状、矿物元素和矿物显微结构之间的相关关系，以确定过剩氩在高压白云母中赋存的主要控制因素。初步得出了以下结果：1、高压变质的正片麻岩中的白云母中不含过剩氩；2、高压白云母中过剩氩的赋存和Mg/有着正相关关系，而和Na/呈负相关；3、激光微区氩-氩分析表明，榴辉岩中的单颗粒多硅白云母存在年龄梯度；4、初步否定了高压白云母中过剩氩来自于流体的说法；5、初步认定，榴辉岩中多硅白云母中过剩氩主要是在高压-超高压变质过程中由内部继承的；6、在阿尔金及柴北缘等地围岩为碳酸岩的榴辉岩中的高压白云母不含过剩氩。上述研究结果将推动过剩氩成因研究走向深入。
