Indication of heavy minerals of Baiyinnuoertin polymetallicdepositinChifeng

白音诺尔矿田是大兴安岭南段著名的锡、铅、锌、银、铜多金属矿田,至今已开采超过40年。近年来通过自然重砂测量相继发现了哈力黑坝锡矿和腰尔压锡矿,本文介绍了重砂测量的方法过程,自然重砂配合人工重砂方法在哈力黑坝锡矿找矿中的应用,并通过对重砂异常特征的分析指出了矿田北锡南铅锌的矿产分布格局,指出了哈力黑坝-腰尔压异常区锡矿找矿前景以及白音诺尔铅锌矿西部火山岩覆盖区铅锌找矿前景。

Baiyinnuoer ore field is a famous tin,lead,zinc,silver and copper polymetallic ore field in the southern section of the Great Hinggan Mountains,which has been exploited for more than 40 years.In recent years,Haliheba Tin Mine and Yaoeryao Tin Mine have been discovered successively through natural heavy sand survey.This paper introduces the method process of heavy sand survey,the application of natural heavy sand combined with artificial heavy sand method in Haliheba Tin Mine prospecting,and points out the mineral distribution pattern of lead and zinc in the north and south of the ore field through the analysis of abnormal characteristics of heavy sand,The tin ore prospecting prospects in HalihebaYao'er pressure anomaly area and the lead-zinc ore prospecting prospects in the volcanic rock coverage area in the west of Baiyinnuoer leadzinc mine are pointed out.
