GENSIS AND POSSIBLE PROSPECTING AREAS OF NEW TYPES OF GOLD DEPOSITS IN THE NORTHERN MARGIN OF THE NORTH CHINA PLATFORM

The dynamic-metamorphic hydrothermal gold deposit(paishanlou type) occurred in ductile shear zone of Archeozoic greenstone formation, turbidite-hosted gold deposit occured in early or meso-Proterozoic metaclastic for-mation(Maoling type, Baiyun type),and K-altered rocks type of gold deposits related to metasomatic-anatectic granitoid are three new types of gold deposits. They were found out and prospected before bng. There are great potentail gold resources at them The potentail regional gold content and favorable remobilization agents are basic conditions for the formation of gold deposit. The basic mechanism of gold metaliogeny is characterized by double remobilization and concentration of gold in source beds. The study of stable isotope might confirm the remobilization metaliogeny of gold deposit.
