| 摘 要： | 永安小陶锰矿床形成于闽西南坳陷带次级构造单元胡坊-永定隆起东侧。矿体产于石炭系下统林地组上部含锰岩系中。主要矿体均受含锰岩系、后期构造变动、风化作用的控制，矿体呈似层状、透镜状。矿石具独特的风化淋滤型矿床的结构和构造。矿物组分简单，品位富，但矿体规模小。锰质来源于陆源碎屑，为风化淋滤型矿床。

| Abstract: | The Xiaotao manganese deposit in Yongan is situated on the eastern side of Hufang-Yongding uplift which belongs to the secondary tectonic unit of Southwestern Fujian Geotectogene and its orebodies are found in the manganese-bearing rock series of Lower Carboniferous.The main orebodies are controlled by the manganese-bearing rock series, post-stage tectonic events and weathering and show the form of stratoid and lenticular.The ores are in possession of structures of weathering-leached deposits.They are simple in mineral composition and high in grade but smaller in scale.The manganese in the Deposit is derived from the terrigenous fragments.The Deposit belongs to the weathering-leached deposit. |
