山东省海阳市土堆沙旺地区金矿床原生晕分带特征及找矿前景

Zoning Characteristics and Prospecting Prospects of Primary halo in Gold Deposits in Tudui-Shawang Area in Haiyang City of Shandong Province

摘要:

土堆沙旺金矿床位于胶莱盆地东北缘，为牟乳成矿带的组成部分。选取464线、480线、532线3个勘探线剖面并采集样品，通过分析样品中Au，Ag，Hg，Cu，Pb，Zn，Ni，Co，As，Sb元素的含量；进行原生晕找矿，经对比分析，3条线分带序列大致符合我国金矿的原生晕理想分带序列，但也有异常。推测T31矿体、T32矿体深部具有深部找矿前景，S39矿体深部找矿潜力不大。

Abstract:

Tudui-Shawang gold deposit is located in northeastern margin of Jiaolai basin. It is a part of Mouru ore-forming belt. Selecting exploration profiles of No.464 line, No.480 line and No.532 line and collecting samples, through analysis on the contents of Au, Ag, Hg, Cu, Pb, Zn, Ni, Co, As and Sb, primary halo prospecting has been carried out. Through comparation and analysis, zoning sequences of three lines are roughly confirm with zoning sequences of primary halo in China. It is conducted that there are prospecting prospects in deep part of T31 ore body and T32 ore body, while there is little potential in the deep part of S39 ore body.
