Wuyi-Yunkai area is located in the central part of cathaysia block

is an important magmatic belt in southern China

and the magmatic during early Yanshan period distributes widely

it have experienced 170

165-150

145-130 Ma three magmatic activity stage

and have an important impact on mineralization during the early Yanshanian. The geological significance is extraordinary here

and Wuyi-Yunkai area is the space-time region that many geological scholars continue to explore

magmatic source region is deep in the earth’s mantle

so it promotes many geological scholars do researches on mantle plume. Recently the Jurassic magmatite are changed to Cretaceous geological magmatite

that also makes "the late Jurassic eastern plateau" issue become a hot topic. This area enriches Ag

Pb

Cu and other elements

and metallogenic was affected by multiphase of magma

deep and hypabyssal intrusive rocks promoted to form different deposits.
