摘要
Jiagongtai gold mine is located at the Caledonian fold belt in Qilian Mountain,the contact part between rise in the middle Qilian and back-arc basin in the south Qilian.Gold bodies are hosted in the Lower Ordovician upper rock group,lithologically,gold-bearing rock are tectonic breccias and biotite plagiogranite.By analyzing the metallogenic condition and ore-controlling factors,it is believed that it is a lower-moderate thermal alteration cataclasite gold deposit,the source of gold formation mineral is the porphyritic granite intruded during Variscan Period.
