四川壤塘金矿带成矿地质条件及其找矿方向

METALLOGENIC GEOLOGIC SETTING AND PROSPECTING TARGETS OF THE ZAMTANG GOLD ZONE,SICHUAN

通过对壤塘金矿带已知矿床及物化探异常等成矿信息的研究，确认“地层、岩浆岩、构造”三位一体的复合成矿条件，总结找矿标志，提出找矿方向。初步认为本区金矿的工业富集形成于晚印支期—燕山期岩浆（期后）热液活动阶段，表生淋积作用对矿床改造富集起着极为重要作用。

Composite metallogenic geological setting including horizon,magmatic rock and structure(three in one),prospecting criteria and prospecting targets in the Zamtang gold ore zone are put forward on the basis of study of discovered gold deposits and geochemical anomalies The gold deposits in this zone were formed in the Indo Chinese postmagmatic hydrothermal stage Supergene leaching is of great importance to rework and enrichment of the deposits
