云南会泽县金牛厂磷矿地质特征及找矿方向
|
摘要
金牛厂磷矿赋存于寒武系下统渔户村组第三段,属海相沉积型磷块岩矿床,矿体延伸稳定,其产状与地层产状一致,矿体受层位控制明显,生物成矿作用贯穿始末。该矿区地质构造简单,含矿岩层出露完整,具有较好的找矿潜力。
Jinniuchang P deposit is in Lower Cambrian Yuhucun Formation Member 3,belonging to the marine facies sedimentary phosphorite deposit. The extension of orebody is stable,and the occurrence is consistent with that of the strata. The orebody is controlled clear by the horizon. The biological metallogenesis takes place from the beginning to the end. The geological structure in this orefield is simple. The ore-bearing bed is complete,with good prospecting potentiality.
