我国的硫化矿床和其他一些含方铅矿的金属矿床,大部分形成于中生代,少数形成于古生代、新生代或先寒武纪。它们主要分布于南岭地区、长江中下游云贵高原和东北地区,在秦岭、西北和青藏高原也有一定规模的出露。在我国东部环太平洋带广泛发育的含硫化物多金属矿在成因上往往与燕山期的花岗岩侵入或火山活动密切相关。但在全国各地也有不少产于碳酸盐和含有机质地层中的铅锌矿或多金属矿与岩浆活动没有明显关系,并且受一定地层层位控制。为了查明这些矿床的物质来源和成矿机制,历年来已对这些矿
Most of the sulphide ore deposits and other galena-bearing metallogenic deposits in China were formed in the Mesozoic, with a few formed in the Paleozoic, Cenozoic or Precambrian. They are mainly distributed in the Nanling area, the Yunnan-Guizhou Plateau and the northeast region in the middle and lower reaches of the Yangtze River, and also have some exposures in the Qinling, Northwest and Qinghai-Tibet Plateau. In the eastern Pacific Rim, the sulfide-bearing polymetallic deposits, which are widely developed, are often closely related to granite intrusions or volcanic activities in the Yanshan Period. However, there are also many lead-zinc ore or polymetallic ores produced in carbonate and organic-bearing formations across the country that are not significantly related to magmatic activity and are controlled by certain formation layers. In order to identify the material sources and mineralization mechanisms of these deposits, these mines have been available over the years
