| 1. | Geological characteristics of the metamorphic conglomerate in sinian stratigraphy in the luoding area , the western guangdong 罗定地区震旦纪地层中变质砾岩的地质特征 |
| 2. | New observations on phosphatized spheroidal fossils in sinian doushantuoan phosphorites in weng an , guizhou province 贵州瓮安震旦纪陡山沱期磷酸盐化球状化石的新观察 |
| 3. | During the sinian , a series of catastrophic events occurred in the eastern part of the yangtze gorge , including hot , cold and gravity events 摘要长江三峡东部地区震旦纪先后发生了热事件、冷事件、重力事件等突发性灾变沉积。 |
| 4. | The reefs widely developed from sinian to neogene in china , with main reef - forming stages in devonian , permian and neogene , respectively 摘要中国生物礁从震旦纪至新近纪均有发育,分布范围广,并有泥盆纪、二叠纪和新近纪3个主要造礁期。 |
| 5. | The sinian granitoids are immediately related the plate collision , they were formed in the plate collision mounain - building period - post collision elevation period 震旦纪花岗岩类与板块碰撞作用密切有关,是碰撞造山一碰撞后抬升这一过程形成的花岗岩类。 |
| 6. | The main diagenetic stage and relevant rock types are the middle proterozoic assemblage of gneissoid granodiorite - adamellite and the sinean schistosity diorates 主要成岩期及代表性岩类有:中元古界为片麻状花岗闪长岩二长花岗岩,震旦纪为片理化闪长岩。 |
| 7. | The minerogenetic epoch lasted from paleoarchean to sinian , with neoarchean , paleoproterozoic and mesoproterozoic - qingbaikouan being the culmination periods 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。 |
| 8. | Conclusion are obtained as follows : 1 . basin accepted sedimentation since sinian , and strata were well developed . it was marine sedimentary series from sinian to middle - triassic and become continental sedimentary series since late - triassic 主要成果及认识如下: 1 、盆地自震旦纪以来长期接受沉积,地层发育良好,震旦纪至中三叠世为海相沉积体系,晚三叠世以后为陆相沉积体系。 |
| 9. | It agrees with the fact that the gabbro is intruded by late ordovician granitic pluton . the pre - sinian basement strata exposed in the north kunlun massif are later archean - neoproterozoic milan group , changcheng system kaqiang group , jixian system liushui formation and qingbaikou system sulu formation 被蛇绿岩所分隔的昆北地块上出露的前震旦纪基底地层为:晚太古代-新元古代米兰岩群,长城系卡羌岩群,蓟县系流水岩组和青白口系丝路岩组。 |
| 10. | We have concluded that the structural movement of the area can be divided into three stages : the stretching stage from simian to early ordovician , the extrusion and rising stage from middle and late ordovician to jurassic and stable depressed stage of foreland basin slope from cretaceous to neozoic 经研究认为研究区的构造运动,主要分为震旦纪到早奥陶世的拉张阶段、中晚奥陶世到侏罗纪的挤压隆升剥蚀阶段以及白垩纪到新生代的前陆盆地斜坡稳定沉降阶段。 |
