The ore-controlling fault system and its geological significance in Shangshanghe gold belt,Tongbai County in Henan Province

LIU Kuisong;ZHOU Hongxia;The 3th Institute of Geological and Mineral Resources Survey,Henan Bureau of Geo-Exploration & Mineral Development;  
Focusing on the Shang Shang He gold deposit,Through field system geological section survey and mining tunnel observation,The characteristics of ore controlling faults and their relationship with mineralization are summarized preliminarily,The primary and secondary relations of ore controlling structures are determined,and the relationship between different types of structures and mineralization is discussed.Research shows,its ore controlling structure belongs to the R type tensional twist fault in the dextral strike slip system,and has the characteristics of multi-phase activity,The pre-mineralization structure is closely related to mineralization.The gold ore body output and scale are strictly controlled by faults,meanwhile,the strength of gold mineralization is positively related to fracture width,and to a certain extent,determines the type of gold deposits.
