摘要
对小热泉子铜矿进行了一系列物探找矿方法的试验研究工作 ,其中包括 :重力、井中充电激发极化法、高精度磁测、地 -井方式激发极化法、甚低频电磁法、瞬变电磁法、天然电磁场测深、可控源音频电磁法、分布式被动源阵列电磁法及中间梯度激发极化法等。
The Xiaorequanzi copper(zinc)deposit is a newly\|discovered promising copper\|rich deposit.Based on a series of tests on geophysical and geochemical ore\|prospecting work conducted in the ore district,it is found that the gravity method,the borehole“mise\|a\|la\|masse” IP method and the high\|precision magnetic method are most effective ore\|prospecting techniques.The ore deposit occurs in tuffaceous sedimentary rocks of Lower Carboniferous Xiaorequanzi Formation.Therefore,the integrated ore\|prospecting model of the Xiaorequanzi copper(zinc) deposit should be as follows:The ore deposit is closely related to volcanic apparatuses and volcanic depressions; wall rock alterations are composed mainly of chloritization,silicification, limonitization, jarositization and carbonatization; gradient zones of the regional gravity field,aeromagnetic low value zones and Cu,Zn,Pb,Cd composite anomalies in the high copper background area constitute regional geophysical and geochemical anomalous indicators in search for the ore deposit;composite anomalies characterized by high gravity,low magnetic values,high polarizabilities and low resistivities make up direct indicators and important ore\|prospecting clues for discovering and delineating deep primary copper(zinc)orebodies.
