It also showsdependence in Zn-Fe and Zn-Mn. Microelement analysis indicates genetic type of Furong tinallotment is nearly magmatic hydrothermal deposit by content of In, Ga and Cd and thetemperature of mineralization is speculated about 235～248℃ by the value of LogGa/Ge, Zn/Cd,which means sphalerite occurred under mesothermal temperature.

According to crystal shape and color, 4 types of zircon in metarhyolite have been identified: inherited, magmatic, metamophic and mixed zircon.

1根据锆石的晶形和颜色，将本区流纹岩中的锆石分为继承锆石、岩浆结晶锆石、变生锆石以及它们之间的混合锆石。

All of these charac-teristics are similar to those of continental crust transformation series granite in South China,implying that their parent magma may be derived from the unexposed Proterozoic metasedimentary rocks.

这些特征都相似于华南陆壳改造系列花岗岩，它们的母岩浆可能来源于

They are mica, lithium beryllium tantalum and gem bearing peg matite, marine volcanic massive sulfide, magmatic copper nickel, metasedimentary iron, gold bearing low grade metamorphosed carbon clastic rocks and gold bearing ductile shear zone. A great progress has been made in recent exploration of porphyry copper.

已知矿床的主要类型有伟晶岩型矿床、与海相火山岩有关的块状硫化物矿床、岩浆铜镍硫化物型矿床、沉积变质型铁矿、浅变质含碳细碎屑岩型金矿和韧性剪切带型金矿床，近年来在斑岩型铜矿床的找矿工作有了新进展。

If magma is involved, metasomatic skarn can be formed, but this kind of skarn is obviously later than the stratified skarn formed under a closed circumstance.
