造山带斑岩成矿与岩浆铜镍成矿时空共生可能性的探讨
Discussions on the possibility of temporal-spatial coexistence between porphyry deposit and magmatic Ni-Cu deposit
摘要
Abstract
Subduction-related and collisional orogenic belts are the most important geological settings for porphyry mineralization.On the other hand,large magmatic Ni-Cu sulfide deposits have been found in a few orogenic belts,such as the Eastern Tianshan,Eastern Kunlun,and the western margin of the Yangzi Block.It has been proposed that sulfide liquid immiscibility and segregation during magmatic evolution sequestered metals for the formation of porphyry deposits,implying a possible genetic relationship with magmatic Ni-Cu mineralization.However,the comparison,analysis,and discussion in this study demonstrate that there are evident differences between these two deposit types in the petrology of the mineralized intrusions,field relationships of the orebodies,metallic mineral and element assemblages,and the petrogenesis of the related magma.The spatiotemporal coexistence of porphyry deposits with magmatic Ni-Cu deposits has not been documented worldwide.In this paper,the representative geological features,metallogenic processes,and controlling factors of these two deposit types in orogenic belts,as well as related magma origin and evolution,are compared and discussed.We propose that there is no direct genetic link between the two types of mineralization,nor are there shared petrogenetic preconditions for their spatiotemporal coexistence in a single orogenic belt.The conclusions provide some referential foundations.关键词
