Abstract:

Along the Taiyangsi-Pangjiahe metallogenic belt，we have found Xi’anhe gold deposit，xiangtanzi gold-silver deposit，Pangjiahe gold deposit，Liushaogou gold-silver-lead deposit and other large-medium sized deposits， and Sihe gold deposit adjacent with Liushaogou gold-silver-lead deposit.Sihe gold deposit is located in the north side of Dongyu-Taiyangsi fracture of Sinian-Ordovician Danfeng Group，nearly EW-NEE trending secondary faults are more development，magmatic activity is significantly，orebody occurrence in the secondary faults.The mineralization and alteration is defined in the tectonic deformation zone，the range of fundamental and orebodies range consistent，and mineralization is most closely connected silicification，pyritization and party lead mineralization.Taking Sihe gold deposit as the breakthrough point，we analyze the ore-controlling factors of Sihe gold deposit and Taiyangsi area，it is considered that the apparent“the trinity” ore-controlling conditions，and we point out the prospecting direction.

Key words: Ore-controlling factor, Trinity, Taiyangsi gold concentration area, Sihe gold deposit, Gansu Province
