A STUDY ON GEOLOGICAL REMOTE-SENSING FOR THE METALLOGENIC CONDITIONS AND PROSPECTING ORIENTATION OF ZHAO-YE GOLD BELT IN JIAODONG DISJRICT

Gold ore deposits of Jiaodong district are principally distnduted at Zhaoyuan-Ye County area, that is so-called Zhao-Ye gold beld whlch is an important gold resource in China.Some advances have been achieved in the metallogenic conditions, prospecting orientation and prognosis for gold ore deposits in Zhao-Ye district through the combinative research work in geology and remote-sensing. Consequently, the author proposes a primary idea which concerns Mesozoic structure-granite metallogenic model, two tectonic phases and metallogenic evolution. The favourable ore-forming structurat types and mineralization zoning teatures are also discussed here, and regional geological environments similar to the known gold ore zones analysed. So as a result, six metallogenic zones and seven favourable mmeralization sectors and a placer gold prospect are outlined wittiin the working area.
