中文摘要: |
本文以活动论的大地构造学说为指导,对贵州新元古代至今约870百万年的地质记录进行了构造-建造的划分。以威尔逊旋回及造山作用不整合界面为依据,将其分为武陵、扬子—加里东、海西—印支、燕山和喜马拉雅5个构造层,并简述了它们的基本特征;按控制原型盆地地动力背景的不同,划分出10个亚构造层,分别注明它们在地壳结构中的所处部位——盖层或基底。依据一定地质时期和环境条件下形成的、有成因联系的岩石共生组合不同,分别划分出沉积建造49个、岩浆建造9个,并指出它们的含矿性。从而建立了贵州构造-建造完整体系,为重塑贵州地壳构造演化和探讨成矿规律奠定了基础。 |

In this paper, according to the geotectology of activity theory, structure-formation of about 870 million years geological record from Newprpterozoic to this day are divided in Guizhou. According to Wilson cycle and orogenic uncomfortable plane, it’s divided into 5 structural layers: Wuling, Yangtze-Caledon, Heisey-Indosinian, Yanshan and Himalaya, their basic features are also summarized: for the difference of control prototype basin dynamic background, 10 sub-structural layers are divided, their positions of crustal structure-caprock and basement are marked. According to the difference of genetic relationship rock paragenetic assemblage formed in some geologic period and environmental condition, 49 sedimentary formations and 9 magmatic formations are divided, their ore-bearing potential are pointed out. So the absolute structure-formation system are built up, it will be the base for crustal structure evolution and metallogenic regulation discussion of Guizhou. |
