斑岩铜矿的勘查模式

EXPLORATION MODEL OF PORPHYRY COPPER

在详细研究斑岩铜矿普查准则的基础上，将其划分为矿化直接标志、矿化间接标志、矿化的有利地质前提和有利地质前提的间接标志４类。并以此与矿床产出的３种类型：地表矿、浅部矿和隐伏矿相联系，作为建立矿产勘查模式的基础。对矿产勘查技术手段区分出专门测试型、综合调查型和探矿工程型，指出了它们在建立矿产勘查模式中的不同作用。在针对不同产出类型建立班岩铜矿矿田和矿床的矿产勘查流程的基础上，提出了斑岩铜矿勘查模式。

On the basis of detailed research of general survey rules of porphyry copper, it can be divided into four types: the mineralization direct mark, the mineralization indirect mark, the beneficial geological premise of mineralization and the indirect mark of beneficial geological premise. Moreover, they are related to the deposit occurrence of three types: surface mine, shallow mine and concealed mine,which is the basis of establishing the minerals exploration model. The paper divides technology methods of the minerals exploration into specialized-test type, synthetical-survey type and prospected-project type, and points out their different function in establishing the minerals exploration model.on the basis of distinguishing different occurrence types which establish the minerals exploration circuit of the porphyry copper mine field and deposit, the exploration model of porphyry copper is advanced.
