摘要
Abstract
According to the origin of molybdenum deposit in China,it can be divided into three categories:porphyry molybdenum deposit;skarn type molybdenum deposit;pulsed molybdenum deposit.Various types of deposits have different characteristics of surrounding rock and ore body characteristics.But all types of deposits in the cause and material sources have their own evolution process,all belong to the granite porphyry magmatic hydrothermal deposits.The porphyry-type molybdenum deposits are the same as those of the skarn-type molybdenum deposits.They belong to the high-temperature strong acid granite porphyry series.Only the skarn-type molybdenum deposits Card rock or carbonate rock series.The porphyry-type molybdenum deposits are all chemically stable rocks,such as volcanic rocks,quartzite and schist.No matter what type of ore deposits,most of its ore-bearing strata is the Precambrian old strata.In the metallogenic age,the age of the ore parent rock is the late Jurassic-Late Cretaceous Yanshanian period,which is the main mineralization period or storm period of China's molybdenum deposit.While the pulsed molybdenum deposit is only a collection of ore-like mineralized bodies that are converted into mineralized hydrothermal fluids along the larger fissures during the process of ore-rock massation of porphyry-type molybdenum deposits.Accounting for only 1％ of the total amount of molybdenum ore in China.It can be seen that the main direction of geological workers is porphyry-type molybdenum deposits,followed by skarn-type molybdenum deposits.关键词
