| 2. | Geochemistry of the mesozoic and cenozoic detrital rocks and its constraints on provenance in the southeast foot of dabie mountains 大别山东南麓中新生代碎屑岩地球化学特征及其对物源的制约 |
| 3. | Based on the authigenic and clay mineral assemblage , two types of diagenetic ambient have been recognized in the meso - cainozoic detrital rocks in tarim basin 根据自生矿物与粘土矿物组合,在塔里木中新生界碎屑岩中可以识别出两种成岩环境。 |
| 4. | The lamellibranchiiiata fossils and coral fossils of upper carboniferous period had been discoveried in the detrital rock and carbonafite rock by the geologic survey of the area of yishenjilike mountain 摘要通过对伊什基里克山特克斯达坂一带地质调查,首次于该区发现了一套含晚石炭世双壳、珊瑚、腕足及植物化石的碎屑岩。 |
| 5. | It is considered that the sequence evolution in the palaeozoic went through the following three stages , the filling of evaporate platform , the filling of carbonate and detrital rock mixed deposits in epiric sea , and the filling of detrital deposits of lake - deltas in paralic inland sag 认为研宄区古生界层序演化经历了以下三个阶段:蒸发台地充填阶段、陆表海碳酸盐岩与碎屑岩混合沉积阶段,以及近岸内陆坳陷的湖泊三角洲碎屑岩沉积阶段。 |
| 6. | The lower paleozoic strata in the south kunlun massif are kulafuhe group of cambbrian - ordovician . they consists of metamorphic detrital rocks , limestone , magnetite - bearing basalt , quartzite ( meta - silicalite ) , which suggests that they might form at active continent margin . the geochemical characteristics of volcanic and detrital rocks do indicate that they might form at an active marginal environment such as island arc etc . associated with the qimanyuter ophiolite suit , there are lots of early paleozoic granitic plutons 在昆南地块上的早古生代地层为寒武?奥陶系库拉甫河岩群,由变碎屑岩、灰岩、含磁铁矿玄武岩、石英岩(变硅质岩)等组成,显示其比昆北地块有较大的活动性,火山岩和碎屑岩的岩石地球化学特征也反映为岛弧及活动边缘环境。 |
| 7. | 5 . based on the analysis of their source rocks , the mesozoic detrital rocks in feixi area are mainly derived from metamorphic rocks of fuziling and luzhengguan groups , and the provenance of fenghuangtai formation is a disappeared ultra - high pressure metamorphic rock unit characterized with inland arc eclogites 物源分析表明,位于肥西地区中生代碎屑岩主要来自佛子岭群和卢镇关群变质岩,凤凰台组的源区来自于一个已经消失的以岛弧榴辉岩为代表的含超高压变质岩单元。 |
| 8. | The formation of a petrofabric is mainly composed of volcanics interlated with minor detrital rock , that of b petrofabric mainly detrital rock inter lated with minor volcanics , and that of c petrofabric mainly carbonate rock . the evidences in geochemistry character demonstrate that metamorphic volcanic rock of the a petrofabric belong to calc - alkaline volcanic rock 在代表性岩石原岩研究的基础上确立了各岩组的原岩建造类型,它们分别是: a岩组主要为一套火山岩夹碎屑岩沉积建造; b岩组主要为一套碎屑岩夹火山岩建造; c岩组主要为一套碳酸岩建造。 |
