Progress and records in the study of endogenetic mineralization during collisional orogenesis

To develop and perfect the theory of plate tectonics and regional metalloge ny, metallogenesis during collisional orogenesis should be thoroughly studi ed and wilt attract increasing attention of more and more scientists. This paper presents the main aspects of research and discussions on metallogenes is during collisional orogenesis after the development of plate tectonics, and accordingly divides the study history into two stages, i.e. the junior stage during 1971-1990 and the senior stage after 1990. Beginning with the negation of mineralization in the collision regime by Guild (1971), the foc us of study was put on whether there occurred any mineralization during col lisional orogenesis at the junior stage. At the senior stage, which is init iated by the advance of metallogenic and petrogenic model for collisional o rogenesis, scientists begin to pay their attention to the geodynamic mechan ism of metallogenesis, spatial and temporal distribution of ore deposits, o re-forming fluidization, relationship between petrogenesis and mineralizati on in collisional orogenesis, etc, Abundance of typical collisional orogens such as Himalayan, China has best natural conditions to study collisional metallogenesis. Great progress in the study of metallogenesis during collis ional orogenesis has been made by Chinese geologists. Therefore, we hope th at the Chinese geologists and Chinese governments at various levels to pay more attention to the study of collisional metallogenesis. Some urgent prob lems are suggested to be solved so as to bring about breakthroughs in the a spects concerned.
