花岗岩浆热液矿床成因研究的困局与突破
Predicament and breakthrough in the metallogenic study of granite-related magmatic—hydrothermal deposits
摘要
Abstract
A large amount of granite and its derived magmatic-hydrothermal deposits are contained within the continental crust,providing a rich resource of rare metal minerals.The traditional metallogenic theory believes that after the granite magma emplaces,it can produce a high-temperature ore-containing aqueous solution through crystal fractionation,which is transported and stored in an extensional tectonic space to form a magmatic-hydrothermal deposit.However,there are serious application problems in the two deciding elements of this mineralization mechanism(fractional crystallization and gas-liquid metamictization),which has led to the inability of this theoretical model to effectively guide mineral exploration to date.This study uses the deep-seated magma chamber that lasts for a long time(>20 Ma)as the breakthrough point to elaborate on the complete and self-consistent mineralization process related to this(ore material)"source-transport-storage",and then clarify the prospecting indicators in space and time of the magma-hydrothermal deposit.The metallogenic model proposed in this study not only enriches the mineralization theory,but also has particularly important guiding significance for deep exploration of rare metal deposits.关键词
