摘要
上庄磷矿为一大型低品位磷灰石矿床,伴生有益组分有铁、蛭石化黑云母及稀土元素。矿床产于黑云母单斜辉石岩体中,含矿岩体由多岩相带组成。通过对该矿床地质特征研究认为,该矿床严格受断裂构造及岩相带的控制,深部的岩浆沿断裂运移过程中不断分异、分次侵入和结晶再分异,导致有益组分磷、铁和稀土富集成矿,属岩浆晚期分异磷灰石矿床。
The Shangzhuang apafite deposit is a low - grade apafite deposit associated with Fe, vemiculitizated biotite and REE. The deposit is confined to the biotite clinopyroxenite. The ore - beating rockbody consists of several lithofacies. The geological features indicate that the deposit is controlled by fracture and lithofacies. This deposit is a late magmatic differentiated one.
