| 7. | They all belong to the calc - alkaline island arc series and are closely related to the evolution of the arc - basin systems of the gangdise tectonic belt . based on studies of petrology , litho - geochemistry , tectonic setting , petrogenesis and magmatic evolution , the present dissertation summarized the general evolutionary regularity of the magmatic rocks in time and space . the magmatic rock assemblages are divided into the inter - arc spreading basin t 在对研究区主要矿产分布特征、成因类型系统分析的基础上,总结了措勤地区构造岩浆演化与成矿的关系,并将研究区成矿系统划分为汇聚大陆边缘成矿巨系统、碰撞造山成矿巨系统和陆内汇聚成矿巨系统。 |
| 8. | Based on an integrated analysis of the surface geological , aeromagnetic , gravity , mt and seismic data from the area of mangnai to serteng mountains in the western qaidam basin , the authors think that the qaidam basin is sandwiched between the north kunlun block and serteng tectonic belt , including two first - order tectonic units the qaidam block and the southern margin of the qilian block and four second - order tectonic units the northern margin of the north kunlun block , qaidam basin , serteng tectonic belt and suhai lake basin in the south of the qilian block 摘要通过柴达木盆地西部茫崖赛什腾山地表地质、航磁、重力、大地电磁测深和地震资料的综合分析,认为柴达木盆地夹持在昆北地块与赛什腾构造带之间,其中包括柴达木地块与祁连地块南缘2个一级构造单元和昆北地体北缘,柴达木盆地,赛什腾构造带和祁连地块南部的苏干湖盆地等4个二级构造单元。 |
| 9. | Zijingguan fault zone is the main structure in taihang mountains that are located in the central part of 20 ~ 30 ne - striking daxing ' anling - taihan - wuling tectonic belt . it is composed of two diagonalized faults that are wulonggou - shanghuangqi fault located in the west and zijingguan - lishan fault in the east 紫荆关断裂带是大兴安岭?太行山?武陵山构造带中段太行山地区的主体构造,总体走向20 30 ,由西侧的乌龙沟?上黄旗断裂和东侧的紫荆关?灵山断裂左阶斜列组成。 |
| 10. | Through the gee stress test of finite points and finite element back - analysis , the paper concludes the geo - stress distribution pattern in different tectonic belt and various lithology strata , which will supply references to mining , design and farther decision making 摘要通过对有限个点的地应力测试,结合已知的工程地质条件,进行有限元反演计算,并对结果进行分析,得到不同构造带应力分布规律和不同岩性地层地应力的变化情况,为煤层开采设计和进一步的决策提供重要的参考依据。 |
