武定地区区域矿产资源极丰富，矿区经过40多年的勘查，共发现各类矿点百余个，综合研究表明，武定县平地耀左所铜矿床类型以“东川式”铜矿最重要，分布在金钟罩、鸡冠山、油基田、周家箐、走马地、黄龙河、牛德庄等地；次为稀矿山式，主要在蒿枝地，走马地等地。“东川式”铜矿：落雪组底部过渡层，“稀矿山式”铁铜矿：因民组下部，同生断裂旁侧，古火山机构中的火山洼地，火山旋回的中上部，富含Na2O的细碧角斑岩系，硅质岩、萤石岩、钠长岩等喷流岩以及黑云母、绿泥石火山凝灰岩的分布区。%Regional mineral resources of Wuding region are extremely rich, after 40 years of mining exploration, all kinds of hundred mines were found. Comprehensive studies show that, "Dongchuan style" copper mine is the most important mine in Wuding Pingdi-Zuosuo copper deposits, which located in Jinzhongzhao, Jiguanshan, oil-based fields, Zhoujiaqing, Zoumadi, Huanglong River, Niudezhuang etc.;Dilute mine type is the second important, mainly in Artemisia sticks, Zoumadi and other places. "Dongchuan style" copper mine: bottom snow group buffer layer; "dilute mine type" iron-copper: due to the lower part of the public group, contemporaneous faults flanking the ancient volcano volcanic depressions institutions, volcanic cycles in the upper rich Na2O of spilite porphyry system, chert, fluorite rock, rock and other jet albite rock and biotite, chlorite volcanic tuff distribution.
