Yunnan Yi The Door Fongshan Copper Deposit To Pierce Constructed Ore-controlling Law

Yimen Shifengshan Copper deposit is an important copper ore production base, which has a long history. Fengshan deposit is main part of the mining. Based on teacher's commitment of Yimen copper mine reconnaissance in deep and peripheral technologies and the Southwest stratabound polymetallic deposit summary of the law. The research group had to construct the main line by piercing the spatial relationship between the piercement structure and the ore body, in place mechanisms and the genesis for study. Through field observations, large scale catalog, various geological and structural elements of tectonic measurements in addition to microscopy on tectonic micro-cracks interspersed relationship.Studies have shown that from diapir to dolomite, alteration, structural deformation intensity, mineralization strength changed in regulations. Ore body piercing mainly in the crack dolomite of silicified and limonite. Copper mineralization, the development of diaper and the structural deformation intensity, altered strength showed a positive correlation. Through the main ore-controlling structures of the deposit we found that the NE ore-controlling fault have the left transtension display characteristics, resulting in ore bodies show the direction of southwest side along the fault Piercing structures formed in the tensile region of the contraction to the conversion phase, which the frequent and strong volcanic activity influence on the formation of ore bodies. The activity has bring transformation, enrichment and provide good conditions for ore bodies. The process of piercing structures pierced up with spiral movement feature, resulting in different morphological changes in the each mining plane.. Based on research results of the law of Pierce structural control, to predict Fengshan ore deposit in depth, whichi have achieved remarkable results.
