According to tectono stratigraphical division principle, different units in Kangguertage Huangshan collision zone, Eastern Tianshan, are divided into order and disorder two types of stratum rock associations, which belong to two kinds of different tectono volcanic activity belts. The collision ororeny and ductile shear zone have a strong space time coupling. Based on the island arc bearing volcanic rock on both sides of the collision zone, time of ore forming and rock forming, characteristics of collision granit, geochemical province, special multistage collision orogeny and intracontinental orogeny basin forming developed features have been found. Gold and copper deposits, with the relation to the collision orogeny, are divided into seven genetic types. The ten metallogenic zones are classified into two kinds of ore forming system of paleo continental margin. Metallogenesis of gold deposits can be classified into five stages. Gold and copper deposits are distributed in belts with the relation to the development of the collision orogeny. The distribution of main large scale copper deposits in the north part of the collision zone and most large middle scale gold deposits in the south part of the collision zone can direct the prospecting for gold and copper deposits. The actual targets are put forward. 展开更多
