Title: The mineralization geological characteristics and the deposit comparison of Tuwu largest type porphyry copper deposit in eastern Tianshan Mountain
Abstract: Tuwu largest type porphyry copper deposit is located in the island arc environment in the south margin of Turpan Hami continental segment of eastern Tianshan Mountain Many stages of magmatism and mineralization are the main reason of the copper metal unusual accumulation, the volcanic activity and hot spring which boils and spreads in the sea bottom make the copper metal preceding concentration (source bed), and the enplacement and superimposition mineralization of dioriteporphyrite and plagiclases granitic porphyry in the some space makes the copper metal accumulate further and forms the deposit finally The volcanic rock which is composed of spilite keratophyre mainly erupted in tidal flat littoral environment The diorite porphyrite and plagiclases granitic porphyry are formed in the shallow place of the earth crust The mineralization occurs in the strong oxidation environment, so the pyrite which is the indicator mineral of the high reduction environment is little The ore low tenor, its structure, alteration characters and formation are the typical characters of the porphyry, but the ore high tenor ,the strong silification and the low temperature in which the deposit formed are the characters of the hydrothermal deposit (subvolcanic hydrothermal deposit) Compared the typical porphyry copper deposit and subvolcanic hydrothermal deposit, the Tuwu copper deposit type is also the type of porphyry deposit and has its own character
