白牛厂矿区成矿模式与深部成矿预测

The Metallogenic Model and Deep Metallogenic Prediction of Bainiuchang Mine

为了认清白牛厂矿区深部矿体分布规律,基于矿床地质特征及成矿模式开展了深部成矿规律与成矿预测研究。结果表明,白牛厂矿床属于沉积—改造—岩浆热液叠加综合作用形成的矿床,主要控矿地质因素有构造作用、岩浆作用及沉积作用。矿区主要有燕山期花岗质岩、中寒武统田蓬组地层岩石等6类深部找矿标志。此外,得到了4个深部成矿区域,分析了预测区的地质条件、主要参数及工程条件,并通过钻孔工程验证了成矿预测区的准确性。

Based on geological characteristics and metallogenic model,metallogenic rules and mineroge-netic region predictions were carried out to understand the distribution of Bainiuchang mine in deep are-as.Results show that the deposit is formed due to the coupling effect of sedimentation,transformation and superposition of magma hydrothermal solution.There are mainly Yanshanian granitic rocks,the Middle Cambrian Tianpeng strata and 6 kinds of deep prospecting marks.Furthermore,four minerogenetic re-gions in deep area were obtained.The geological conditions,parameters and engineering environments were analyzed.The accuracy of the predicted minerogenetic regions was confirmed by borehole prospec-ting.
