论地洼区的岩浆控矿作用

ON MAGMATIC CONTROL OF ORE DEPOSITS IN DIWA REGIONS

西伯利亚东部阿尔丹—斯坦诺夫地区一些前寒武纪Fe、Cu—Ni、Pb—Zn、REE矿群与远东滨海活化区达尔聂哥斯克中新生代Pb—Zn和B矿群的对此研究表明:原地洼矿群与中新生代矿群在其大地构造-岩浆环境方面有许多共同点,两者均受深断裂交汇的控制。这些深断裂在初生的富钾基性岩浆的多次上升过程中充当通道。

Comparison of some Precambrian clusters of Fe, Cu-Ni, Pb-Zn. REE deposits of the Aldan-Stanovoy region of the Eastern Siberia with Mz-Cz Dal'negorsk cluster of Pb-Zn and B deposits at the activized Far East Maritime region shows that protodiwa and Mz-Cz ore dusters reveal much in common in tectonic-magraatic setting. Both are controlled by intersections of deep-rooted dislocations which served as passways for recurrent ascent of juvenile, basic and potassium enriched magmas.
