对于火山岩中块状硫化物矿床的勘探涉及到识别象绿岩带这样有利的地质环境和确认其岩带中最有利于进行详勘的地区.经常用路线地质和地球物理测量来确定有利的地质环境,还经常可以用蚀变矿物学和成矿元素地球化学的知识,参照已知矿床周围出现的模式来确定靶区.热液成因的绿泥石的出现以及许多火山岩矿床下部补给带内异常富的铜含量就是这种特征的例子.热液绿泥石和铜的高含量出现在矿体附近,且范围局限.它们一旦在初期钻孔中 Exploration of massive sulphide deposits in volcanic rocks involves the identification of favorable geologic environments such as greenstone belts and the identification of the most favorable areas for detailed surveying of the lithosphere.The route geology and geophysical surveys are often used to determine the favorable geology Environment, the target area can often also be identified using alteration mineralogy and knowledge of ore-forming elemental geochemistry, with reference to the patterns occurring around known deposits, the occurrence of chlorites of hydrothermal origin and the presence of anomalies in the lower recharge zones of many volcanic deposits An example of such a feature is the rich copper content, and the high levels of hydrothermal chlorites and copper occur near the ore body and have a limited range, and once they are in the initial borehole
