摘要
斑岩型铜矿床是重要的铜矿类型 ,在已探明的铜储量中斑岩型铜矿居首位。研究认为 ,在板块构造的敛合带上 ,斑岩铜矿发育地区 ,常见有角砾状地质体和角砾岩筒。这些角砾状地质体和角砾岩筒对矿化与富集起着重要作用 ,是斑岩铜矿的重要找矿标志 ,有时其本身就是铜矿体。本文中从理论与野外工作相结合的角度 ,总结了与斑岩型铜矿床有关的角砾状地质体和角砾岩筒的类型及地质特征 ,通过具体实例介绍了与斑岩铜矿有关的角砾岩筒的找矿思路与方法 ,适宜野外工作的实际应用。
Porphyry copper deposit belongs to the important type of copper deposits and heads the list of demonstrated reserves in all types of copper deposits. The research results show that the porphyry copper deposits are mostly associated with the breccia body and breccia pipe. The breccia pipe plays an important role in metallogenesis and enrichmant for the porphyry copper deposits and is an important prospecting indication, and some time the breccia pipe itself is ore body. In this paper, from the view of the combination of theory and field practice, the author summed up the types and geological characteristics of the breccia pipe associated with porphyry copper deposit, and introduced the mineral prospecting methods of the breccia pipe by example, all of which are suitable for the practical application of field work.
