Abstract:

Luerba gold deposit is a large carlin type deposit occurred in the epimetamorphic sedimentary rocks of the Middle Triassic in western Qinling mountain.Through studing geological characteristics,hydrothermal activity and wall-rock alteration,analyzing ore-controlling condition,we consider that clasolite-carbonatite construction of Middle Triassic are parent rocks of gold mineralization.The ore-controlling structure  role of EW-trending is obvious,and rich orebody always occurs in the zones where NW and EW-trending fractures intersect.The quartz dioritic porphyrite,which likely provides energy to the gold bearing solution transportation,plays a significant role in gold ore-forming process.Further analyzation shows that Luerba gold deposit is a large carlin type deposit,which formed under epithermal to mesothermal environment.Besides,the carbonates bearing clastic rock formation,the intersect zone of NW and EW trending fractures,and the quartz diorite porphyrite are beneficial prospecting indicators,the ore belt has the characteristics of equidistant parallel distribution,so we regard these factors can be as the focus of next prospecting.

Key words: Geological characteristics, Genesis, Metallogenic regularity, Luerba gold deposit, Gansu Province
