摘要
肥城钾长石矿属钾长伟晶岩型脉状矿床 ,由元古宙末期壳源岩浆侵入活动晚期冷却时形成的硅酸盐残余熔融体沿构造裂隙侵入形成。矿脉具有成群分布的特点 ,较大矿体具有伟晶岩矿床特有的环带状构造。该区钾长石矿资源潜力较大。矿体裸露地表 ,适宜露天开采。矿体内部的块体状矿石质量好、易分选 ,是玻璃、陶瓷等工业领域较理想的生产原料。
Potassium deposit in Feicheng city belongs to potassium-pegmatite vein type. It was formed by residual molten mass intrusion along cracks in later period of magma intrusion in later protogean period. Deposit vein distributes in groups. Large ores have circle-type structure. Potassium resource is very rich in this area. Ores bare in surface which is suitable for mining openly. Block ores in deposit has good quality and is easily chosed, which are good production materials in glass and pottery lines.
