镇宁顶红铅锌矿地质特征

Geological characteristics of Dinghong Pb Zn deposit in Zhenning

镇宁顶红铅锌矿自1957年发现至今,由于以往的工作程度较低,区内仅发现了一个矿(化)体。经收集资料并结合现场踏勘,认为矿体多产出于上石炭统马平组(C_(2)m)与下二叠统垭口田组(P_(2)y)接触带中,岩性以砾状灰岩、薄层灰岩为主。区内铅锌等矿产的形成与岩浆热液活动密切相关,该矿床应属于中低温裂隙充填交代铅锌矿。

Since the discovery of Dinghong Pb Zn deposit in 1957,only one ore body has been found in the area due to the low degree of previous work.Based on the data collected and field survey,it is considered that the ore bodies mainly occur in the contact zone between the upper Carboniferous Maping formation(C_(2)m)and the lower Permian yakotan formation(P_(2)y),and the lithology is mainly gravel limestone and thin limestone.The formation of lead-zinc and other minerals in the area is closely related to magmatic hydrothermal activity,and the deposit should belong to medium low temperature fissure filling metasomatic lead-zinc deposit.
