辽宁省岩石地球化学研究新进展

辽宁地球化学场研究,是根据辽宁全域41种元素丰度及各种地球化学参数,论述了辽宁不同地质时代和构造分区表壳岩石元素分配特点,指出了辽宁重要成矿元素的高值时代;建立了辽宁早前寒武纪变质岩、超变质岩,全域沉积岩,火成岩不同岩类的主元素地球化学模型和元素富集型式;并对Au、Pb、Zn、B等主要成矿元素的分布、分配以及与有关元素的相关特征进行了讨论;指出了成矿元素的主要载体岩石和高值地质单元。根据大地构造分区、元素组合,将辽宁全域划分为4个地球化学省,11个地球化学区,35个地球化学分区。

THE NEW PROGRESS OF STUDYINC LITHOGEOCHEMISTRY ON LOAONING

Through the study of geochemical field, based on 41 element abundances and various geochemical data in all over Liaoning Province, the element distribution character of superficial crustal rocks in different structural zoning and different geological time when they formed have been discussed; high-value time of important ore-forming elements have been pointed out; the main-element geochemical model and the element enrichment pattern of early Pre-cambrian metamorphic rocks, ultrametamorphic rocks have been set up; the distribution of main ore-forming element such as Au, Pb, Zn, B and interrelated characters with some elements have been discussed; the main carrier rocks and high-value geological unit of ore-forming elements have also been pointed out. According to tectonic zoning and element association, all of Liaoning is divided into 4 geochemical provinces, 11 geochemical zones and 35 geochemical partition,
