| 1. | Geology and genesis of the hercynian - indosinian granitic rocks in zhuluke area , western liaoning province , china 八道卡地区岩金成矿特征 |
| 2. | The thermal events of late hercynian movement and late yanshanian movement has great effects on the maturation of source rocks 晚海西运动、晚燕山运动对盆地烃源岩的成熟具有重要的影响。 |
| 3. | The granitic rocks in zhuluke area , western liaoning , emplaced during late hercynian - indosinian cycle , with rb - sr isochronal dating age of 226 . 8 260 ma 摘要朱碌科地区花岗质岩石侵位时间为二叠三叠纪。 |
| 4. | Based on the distribution and petrochemistry of magmatic rocks , the techonic background of sedimentary basin and the mechanism of magmatic activity at the late hercynian in nanpanjiang depression and its adjacent areas , southern china , have been studied 摘要南盘江坳陷及邻区海西晚期岩浆岩分布显示有从中、西部大规模玄武岩喷发中东部中酸性岩浆活动东南部花岗岩侵入的演化规律。 |
| 5. | 4 ) through making maps of cave section correlation in the pleokast topography of the early hercynian movement , three karstic circle are recognized in tahe oilfield , and each circle were produced one cave layer , the top cave are earlier than the down caves 4 )通过海西早期古地貌条件下的四条洞穴对比的大剖面的制作,认为区内普遍发育三个岩溶旋回,并相应产生三套洞穴层,上部洞穴先形成。 |
| 6. | 3 . it is discussed that the buried hill reservoir in this zone experienced karstification in caledonian - early hercynian , indosinian and mid yenshan movement period , and it is indicated that karst formed in late indosinian and mid yenshan movement period are the key periods to form fine reservoir 3探讨了该区潜山储层形成经历加里东、海西早期、印支和燕山中期运动抬升型岩溶作用,指出印支、燕山中期运动抬升型岩溶是形成良好储集层的关键。 |
| 7. | In the late stage of mineralization occurred in the hercynian period , a widespread strong modification of ores or mineralized rocks of early stage caused by intrusion of parental magma of granite - porphyry leads to further enrichment of gold element and eventual formation of the gold deposit 第二期成矿作用是在海西构造运动中,由于花岗斑岩原始岩浆的侵入活动使早期的矿石或矿化岩石受到较强烈改造,使其中的金得到进一步富集,从而构成了现在的矿体。 |
| 8. | Erlian basin is a rift lacustrine basin developed on the hercynian geosyncline folded base in early cretaceous , is featured by simple sedimentary feature , depositional cycle , small lacustrine transgressive , dry climate , salinization lacustrine water and multi - and - near sources 摘要二连盆地是在海西期地槽褶皱基底上发育起来的早白垩世断陷湖泊群,具有湖盆湖浸规模较小、气候条件干燥、湖水咸化、沉积旋回单一,多物源、近物源和粗碎屑等沉积特征,以及发育岩性地层油气藏为主的油气分布特点。 |
| 9. | This thesis studies each structural layer ' s feature : ( 1 ) structural layer of basement : it is a paleozoic folded basement , whose tectonic deformation and magma intrusion is fiercely , and it is affected by the early hercynian tectonic movement and related to the underthrust and closure ( c1 ) of zhungaer ocean basin and the areal pressing of continents ( c2 - 3 ) ; ( 2 ) structural layer of permian : due to the regional extending and fault depression role in mid - hercynian , it occurred to the combinations of structure and magma in santanghu basin and it ' s periphery area , such as a - granite ' s stock , batholiths and diabase ' s dike . there are many fault depressions possible 按照不同构造层,研究了各构造层的构造特征:基底构造层:受早海西期构造作用的影响,与准噶尔洋盆俯冲闭合、而后陆-陆碰撞的区域挤压构造作用有关,为一构造变形和岩浆侵入活动强烈的古生代褶皱基底。二叠系构造层:受中海西区域性伸展断陷作用的影响,盆地及其周缘地区发育与伸展构造有关的构造-岩浆组合,如呈岩株、岩基状侵位的a型花岗岩以及呈岩墙状侵位的辉绿岩等。 |
| 10. | However , the true reason that markit slope are so steep is due to intense tectonic movement of late himalayan . as concerned as this hydrocarbon source regional evolution , the key tectonic movements for hydrocarbon accumulation can be divided into three stage : ( 1 ) middle - late caledonian movement ; ( 2 ) late - terminal hercynian movement ( 3 ) late himalayan movement 给合本区的烃源岩演化史,对本区油气运聚成藏关键性的构造运动有三期:中晚奥陶的伽里东中晚期运动;早晚二叠的海西晚、末期运动喜马拉雅晚期。 |
