摘要
Abstract
Variation of geological variables is closely related to characteristics of geological body. Statistics of the geological variables could reveal certain regularity of the geological body. Result of mathematical statistics of multiple geological events is manifested by several generally overprinted mixture distributions. Therefore, statistics of characteristics of the mixture distribution and single distribution is of guiding significance to understanding genesis, process and characteristics of mineralization. The statistical result shows that gold grade of Qiangma gold deposit is distributed in 2 overprinted logarithmic normal distribution overalls and the overalls are correspondent to two major geological events taken place in the are-a. Study on the vertical variation of the characteristic parameter shows that mineralization is intensified to depth and further exploration should be continued to depth of the gold deposit
