Geochemical study shows that 12 trace elements related gold mineralization can be divided into 5 metallogenic factors （element assemblages）. The high values of F1 , F2 and F4 together indicate overlapped of multiple stages of gold mineralization, revealing high potential of gold mineralization at depth ; the single high value of F4 represents the root of an existing ore body while high values of F3 and F4 show the intervals of barton sectors in the lode. Comprehensive geochemical studies show the high prospeetion potential below the 14^th level and between lines 39-71. It is also prospective to look for blind ore-bodies between lines 15-29 and below the 10^th level.展开更多

There are a reasonable amount of fluid inclusions in the gold deposit,including three types: CO2-H2O-Na Cl inclusions,pure CO2 inclusions and Na Cl-H2 O inclusions,of which most of them are CO2-bearing inclusions. The fluid salinity is 1. 43%- 9. 08%,mainly concentrated in the range of 4. 69%- 5. 41%,the density of CO2 is 0. 69- 0. 80 g / cm3,indicating that the mineralization fluid is low-medium salinity and low density fluid. A series of studies on gold-bearing quartz vein and fluid inclusions show that there exists a positive correlation between the degree of the gold mi-neralization and the amount of CO2 in the inclusions,which means the more CO2-bearing inclusions there are,the higher the content of gold is. CO2 is mainly derived from mantle fluid,and the ore-forming fluid should be derived from mantle fluid and the crust shallow fluid. The conclusions have important denotative meaning on the metallogenic mechanism of orogenic gold deposit and the deep prospecting on metal deposit.展开更多

The potential and the ore-searching direction of the province are also considered. The Haigou gold metallogenic province occurs as an independent province with low denudation degree and high ore-producing potential. Regional fault belts and small basic intrusions are two ore-constrains and could serve as the ore-searching indictors in the province.展开更多
