| 摘 要： | 北冲高岭土矿床位于萍乐拗陷带的西端南缘,矿区地质构造简单。矿体主要赋存于石炭系下统大塘组梓门桥段(C1d3)的中下部,矿体呈似层状、透镜状产出。矿体走向长600~1 200 m,厚2.60~16.97 m。矿石质量纯正,白色,矿石为隐晶质、微晶质结构,角砾状、花斑状、块状及条带状(条纹状)构造;对北冲高岭土矿床中的主要组成矿物进行了化学成分,X-射线衍射仪、差热、红外吸收光谱、扫描电镜等系统分析,证明主要矿物成分为埃洛石,并对其成因进行了简要的讨论,认为北冲高岭土矿床中埃洛石粘土岩应属于风化淋滤后残余堆积而成。

| Abstract: | Kaolin deposits in Beichong area is located in the south and west margin of the geological depression belt of the Pingxiang-Leping,and the geological formations simple.The host rock of main orebody is mid-lower of the Xinmenqiao member(C_1d~3) of Datang formation of Carboniferous.The orebody presents in bedded-like,lens-like.The length of orebody trend is 600~1200 meters,thickness is 2.60~16.97 meters.The quality of orebody is very pure,colour is snow white to white.And the texture of orebody is crytocrystalline and microcrystalline,the structure looks as brecciated;massive and porphyritic;the banded shape(streaked shape).The major mineral is confirmed of Halloysites by the analysts to the major mineral composition of kaolin deposits,such as chemical elements,X-ray diffraction device,differential thermal analysis,infrared absorption spectrum,scanning of a mirror,etc.The Halloysites in kaolin deposits is caused by the stone clay rock remnants and left after weathering drip filter. |
