Geological characteristics and prospecting marks of qieergande gold deposit, akesai county,gansu province

且尔干德金矿位于华北塔里木板块裂解闭合过程中形成的祁连山加里东褶皱带,中祁连隆起、南祁连弧后洋盆地接触部位的南祁连区。且尔干德金矿属中低温热液构造蚀变岩型金矿,金矿体赋存于中奥陶统O2（T+Ss+Sl）岩性段中,含矿岩性为碎裂褐铁矿化晶屑岩屑凝灰岩。本文在研究前人工作成果的基础上,结合近两年的普查成果,总结了金矿的地质背景、矿体特征和找矿标志,找矿前景乐观。

Qieergande gold deposit is located in the north China the tarim plate cracking in the process of closing the Qilian caledonian fold belt, the gold orebody occurrence medial and lower Ordovician series O_2(T+Ss+Sl) lithologic section, limonite ore lithology for rupture wafer crumbs debris tuff.Based on the research achievements on the basis of previous work, combining with the census results of nearly two years, summed up the mine geological background, orebody characteristics and ore-prospecting criteria and prospecting prospect is optimistic.
