武夷地区燕山期成矿特征及找矿方向

METALLOGENIC CHARACTERISTICS OF YANSHANIAN PERIOD AND ORE GUIDE IN THE WOYI AREA

武夷及邻区燕山期成矿作用在环太平洋成矿带中具有四大特色：（１）成岩成矿在时空上从陆内向陆缘发展；（２）岩浆成矿作用具多层次造浆与多层次就位成矿；（３）华夏系列多字型复合构造控岩控矿；（４）成岩成矿具北北东向向洋分带与纬向分带叠加的“双向”分带。武夷地区是寻找火山－斑岩铜、金、锡、银铅锌等矿产的重要成矿带，又是找寻动热变质或花岗岩－剪切带型金矿床的有利地带。

The Yanshanian metallogeny in the Wuyi and neighboring areas of Circum-Pacific Metallogenic Belt has the following three features:(1) magmatism and mineralization developed from the interior to the margin of the continent in space and time;(2)multilayered magma-forming processes and multilayered emplacement characterize the magmatic mineralization;(3)Xi-type(ξ type)compounding structure of Cathaysian series controls magmatic emplacement and mineralization;and (4)rock and mineral zoning shows a “bidirectional”nature demonstrated by NNE-elongated zones arranged towards the ocean superposed by N-S elongated zones. The Wuyi area is an important metallogenic belt favorable not only for prospecting volcanogenic-porphyry copper,gold,silver-lead-zinc deposits, but also for hunting gold deposits related to dynamo-thermometamorphism or granite-shear zone.
