| 摘 要： | 通过对拉拉铜矿床含矿岩系变质岩的岩石学特征、岩石化学和稀土元素特征的深入研究,同时结合多种判别和统计分析,认为其变质条件为绿片岩相,变质原岩为一套以细碧角斑质火山碎屑岩为主和细碧角斑岩与正常沉积的泥质岩、泥质粉砂岩及碳酸盐岩的复杂组合。

| Abstract: | Based on the study of the petrologic characteristics, petrochemistry and REE characteristics of metamorphics of the ore-bearing rock formation in Lala Copper Deposits, combined with several discriminances and statistical analysis. The authors believe that the metamorphic grade was of greenschist facies. The metamorphic preexisting rocks was a complex combination which consisted of spilitekerato Phyrey pyroclastics,claystones,clayed siltstones and carbonate rocks. |
