THE PROSPECTING DIRECTION AND METALLOGENICREGULARITY FOR HOT SPRING-KARST-ALTERATIONROCK TYPE GOLD DEPOSIT IN XIQINGSHAN

Xiqingshan region is a newly discoved metallogenic zone for karst hot spring type of gold deposit, which was formed by the pricipitation and crystalization of suddenly emerged siliceous hydrothermal before the formation of "silicon cap".The secondery tectonics (fissures), caused by arcuate tectonics mechanism of Xiqingshan, and the intermediate acid dike or paleokarst tectonics developing in fissures are the main host structure and ore-control tectonics. On the section,from top to bottom,it presented a "three beds" type of metallogenic regularity, that is hot spring type-karst type-metasomatic alteration rock type. Xiqingshan and Likarushan arcuate tectonics zone possess better future for further prospecting.
