| 摘 要： | 通过室内薄片研究,认为川东北地区长兴组-飞仙关组碳酸盐岩地层中赋存有自生金红石和菱锶矿.应用矿物学理论,并结合电子探针、扫描电镜和能谱成分等测试分析,结果表明金红石为中-晚成岩阶段形成的热水在运移过程中与富含绿泥石质泥土、黑云母碎片的碳酸盐岩围岩发生水岩反应,即从绿泥石、黑云母中析出的Ti元素结晶而成.菱锶矿为中-晓成... |

| Abstract: | Based on the research of slices,the authors consider that there are authigenic rutile and strontianite in Changxing-Feixianguan Formation in the northeast area of Sichuan.The paper indicates that rutile and strontianite are generated respectively by the reactions between the geothermal hot water formed in middle-late diagenetic period and chlorite,carbonate rock in blackmica rich and between that and carbonate rock rich in strontium trough mineralogy theory and analyses including EMP,SEM,and energy spectrum... |
| Keywords: | Northeast Sichuan rutile strontianite mineral characteristics origin analysis |
