| 摘 要： | 通过对康山固体可燃脉体产状、脉石矿物性质、构造发展史的综合分析,认为其成因很可能是下寒武统荷塘组中的软沥青和有机质,在加里东运动期间,由于区域应力体系的变化而爆炸运移形成的。康山脉石矿物是沥青和有机质,不是煤和无机物。沥青的源岩为下寒武统荷塘组富有机质的黑色泥岩、硅质泥岩、硅质岩。康山脉中的固体沥青和有机质,当初挤入时应呈塑性流动状态,康山沥青系由石油经热演化而成。

| Abstract: | According to the comprehensive study of the occurrence, character- istics and structural evolution history , it is considered that Kang- shan combustible lode is a bitumen and organic matter evolved from petroleum, not a coal. The source rock of the bitumen is a black shale, siliceous shale and silicalite of Hetang Fro., Lower Cambri- an, rich in organic matter. Studying its origin, it is believed that it was a soft pitch or organic matter of Hetang Fm., Lower Cambrian. In view of regional stress change during Caledonian movement it ex- plosively migrated into structural fractures. It was once a plastic and movable substance before being squeezed into the shear-frac- tured structural plane. |
