THE PROSPECTIVE BELTS OF THE METALLOGENIC AREA OF THR VOLCANIC ROCK REGION IN EAST FUJIAN

Comprehensive analysis and study of the data of geological structure and regional geophysical and geochemical survey in East Fujian, as well as inter- pretation of the computerised image of remote sensing from Land Satellite, this paper advances several well-connected synthetical exploring indications and distinguishes the best prospective belts of the whole region. The result of the synthetical interpretation of the above data indicates that the intersects of two series of fracture setting on both sides of Fu An-Nan Jing fracture slantways running through the volcanic rock region in NNE direction and the fractures in EW, in NE, NW, NEE, and N N W direction, compose a sequence of active centres of volcanic eruption, magmatic intrusion and mineralization in late mesozoic era and facilitate the development of diversified movement of miscellaneous volcanic-intrusive tectonic depression. These have provided favourable sources and surroundings of mineralization and thus the prospective belts have been formed.
