摘要
研究区位于粤北拗陷及赣中南隆起区,属贵东岩体中部。矿区内矿体为陶瓷土矿及瓷石矿,主要赋存于侏罗世侵入体强风化花岗岩及中风化花岗岩中,矿体均规模属大型。陶瓷土矿中Al_(2)O_(3)含量平均为17.91%,Fe_(2)O_(3)含量平均为0.97%,TiO_(2)含量平均为0.07%,Fe_(2)O_(3)+TiO_(2)含量平均为1.04%;瓷石矿中Al_(2)O_(3)含量平均为14.83%,Fe_(2)O_(3)含量平均为0.80%,TiO_(2)含量平均为0.06%。通过矿石质量综合评价,矿床属优质风化残积型陶瓷土矿及瓷石矿。
The research area is located in the northern Guangdong depression and south-central Jiangxi uplift,which belongs to the middle part of Guidong pluton.The ore bodies in the mining area are ceramic-clay ore and porcelain stone ore,which mainly occur in the Jurassic intrusive strongly weathered granite and moderately weathered granite,and the ore bodies are all large-scale.The average content of Al_(2)O_(3),Fe_(2)O_(3),TiO_(2) and Fe_(2)O_(3)+TiO_(2) in ceramic ore is 17.91%,0.97%,0.07% and 1.04% respectively.The average content of Al_(2)O_(3) in porcelain ore is 14.83%,the average content of Fe_(2)O_(3) is 0.80% and the average content of TiO_(2) is 0.06%.Through comprehensive evaluation of ore quality,the deposit belongs to high-quality weathering residual ceramic clay ore and ceramic stone ore.
