浙江绍兴——龙泉隆起带中金矿床的原生及次生地球化学异常研究

A STUDY OF PRIMARY AND SECONDARY GEOCHEMICALANOMALIES AROUND GOLD DEPOSITS IN SHAOXING-LONGQUAN UPLIFTED ZONE, ZHEJIANG PROVINCE

本文对浙江省绍兴一龙泉隆起带内代表性金矿床的原生及次生地球化学异常特征进行了系统研究,确定了异常中最主要的指示元素以及它们自近矿至远矿、从矿下到矿上的分带序列和组合特征,并总结出在本区及邻区金矿勘查中具有实际意义的综合地球化学找矿标志。

A systematical investigation of primary and secondary geochemical anomaliesaround the gold deposits in Shaoxing-Longquan uplifted zone, Zhejiang Provinceindicates that Au, Ag, Cu, Co, Hg, Pb, Zn, As, Te, Sb are main indicator elementsin the primary anomalies while Au, Ag, As, Hg, Te are indicator elements insecondary anomalies. It has been discovered that the distribution regularity,assemblage as well as vertical and horizontal zonation of these elements are con-trolled by their geochemical properties and by anomaly-forming conditions. Sixcomposite indicators are considered to be of practical significance in prospectingfor gold deposits in this area.
