成矿时代从古太古代到震旦纪，但以新太古代、古元古代、中元古代青白口纪3个地质时期为成矿高峰期。 |
| 6. | The paleoproterozoic wangjiahui granitoid intrusion , west segment of wutai mountains , consists mainly of quartz monzodiorite , granodiorite , monzogranite and adamellite
五台山西段王家会古元古代花岗岩侵入体主要由石英二长闪长岩花岗闪长岩和二长花岗岩组成。 |
| 7. | Integrated with other late paleoproterozoic granitoids within the central tectonic zone , it indicates that there was a tectonic transitional process from extension to compression during late paleroproterozoic in the southern segment of the central zone of ncc
岩石学和地球化学研究表明王家会花岗岩属于后碰撞花岗岩，结合区域上古元古代地质特征，表明华北克拉通中部带南段古元古代晚期的花岗岩构成了与正常造山过程花岗岩浆演化相反的序列。 |
| 8. | 2 . 6 2 . 7ga , these granitoids are most likely to be derived from the partial melting of hybrids both 2 . 6ga metavolcanic materials in archean wutaishan magmatic arc and older continent crustal materials under lower than 1 . 2gpa . petrological and geochemical characteristics of wangjiahui granitoid intrusion suggest that is probably fored under post - collisional tectonic background
2 . 1ga在- 3 . 82 - 2 . 80范围，表明王家会古元古代花岗岩最有可能形成于大约2 . 6ga五台山大洋岛弧火山岩物质和更老的陆壳物质在 |
| 9. | Based on the studies of the " bedding " and " sedimentary relic " of granite in the proterozic strata at huangqikou of the middle part of helanshan , the authors think that the proterozoic granite in the area was produced by metasomatic metamorphism , which formed during the time when the earth crust became thinner
对贺兰山中段黄旗口元古代地层中存在于花岗岩中“层理” 、 “残留体”等地质现象进行研究，认为该地区花岗岩是由元古代沉积岩经过变质交代作用而形成的，这种变质交代作用可能发生在古元古代，在秦祁贺三叉裂谷活动之前地壳变薄的大地构造环境下形成。 |
| 10. | Some conclusions are listed as follows : the plateform cover cap of ordos basin and its circumference areas can be divided into five tectonic sequences . the tectonic evolution of ordos basin can be classified in six stages : the basement formation phase ( from archeozoic to paleoproterozoic ) ; the aulacogen phase ( from mesoproterozoic to neoproterozoic ) ; the north china continental sea phase ( from sinian to early - paleozoic ) ; the north china intracratonic depression phase ( from late - paleozoic to early mesozoic ) ; large ordos inland basin phase and the formation of independent ordos basin ( mid - late mesozoic ) ; fault basin phase around the ordos basin ( cenozoic )
通过研究有以下成果及认识：鄂尔多斯盆地及其周缘地区沉积盖层可划分为五大构造层序，盆地的形成和演化分为六大构造阶段：太古代至古元古代基底形成阶段、中新元古代克拉通内裂陷槽或坳拉槽演化阶段、震旦纪?早古生代华北陆表海盆演化阶段、晚古生代?早中生代华北克拉通坳陷演化阶段、中生代中晚期大鄂尔多斯内陆盆地演化阶段及独立鄂尔多斯盆地的形成、新生代周缘断陷盆地演化阶段。 |
