Characteristics of Superimposed Structural Haloes and Deep-Seated Ore Prediction in the Baoxinggou Gold Deposit of Heilongjiang Province
摘要
Abstract
Baoxinggou gold deposit is located in Tahe county Heilongjiang Province,and was originally delineated through 1:100000 stream sediment survey in 2002,the first ore-body was discovered by 1:10000 and 1:20000 soil survey and the subsequent trenching in 2007. The ore-bodies are mainly made up by altered sandstones,altered diorites and altered dioritic porphytites,secondly by quartz veins,the alteration of rocks took place at mid-dle-low temperatures. This work collected geological and latest drilling sampling data of the Baoxinggou gold deposit to study its geochemical characteris-tics and analyze superimposed structural haloes. The results show that front haloes are indicated by elements Sb and As, near-ore haloes by Pb, Ag, Au,Zn,and Cu, and tail haloes by W, Mo, and Bi, respectively. A model was established to characterize these superimposed haloes, by which this work predicted deep-seated orebodies in the deposit. It suggested that the I-1-1 orebody may have a greater downward extension or there may exist blind ore-bodies below the I-1-3 and I-2-1 orebodies, respectively.关键词
