| 1. | Authigenic mineral assemblage formed in different ambients is distinct to each other 两种环境下形成的自生矿物组合截然不同。 |
| 2. | The data of fluid inclusion analysis showed that the filling of minerals mainly happened during the burial period 各种自生矿物充填的不均匀性揭示了岩石与孔隙水之间相互作用的复杂性,以及岩溶水在不同时期是变化的。 |
| 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. | Authigenic minerals and their occurrence in the meso - cainozoic reservoir sandstones were observed and analyzed by optical microscope , sem , epma and xrd 采用光学显微镜、扫描电镜、电子探针及x射线衍射观察分析了塔里木盆地中新生界储层砂岩自生矿物及其在岩石中的产状。 |
| 5. | The diageneses which are destructive to the reservoirs are mainly the filling of minerals in secondary pores , the fissures and the dissolved caverns 对储层起到破坏作用的主要是充填作用,表现为次生溶蚀孔隙、裂缝、溶洞中充填自生矿物,它们的包裹体测温数据证明充填作用发生在埋藏时期。 |
| 6. | Under the hydrodynamitic condition in the outshelf heavy minerals are enriched to a certain extent . they are of horablede - epidote assemblage and contain some authigene ( pyrite and glauconite ) . the content of stable mineral is small and mineral maturity index ( trzg / hp ) is low 在外陆架水动力的作用下,重矿物有一定富集,重矿物以角闪石?绿帘石矿物组合为特征,含有一定量自生矿物(黄铁矿和海绿石) ,稳定矿物少,矿物成熟度低。 |
| 7. | So the effect of eutrophication of dianchi lake of sediment ca n ' t be ignored . based on the research of modern sediemnt of dianchi lake , the thesis is concerned about some physical and chemical characteristics ( including magnetic susceptibility , ammoniac nitrogen and effective phosphprus etc . ) and thermodynamics analysis of spontaneous mineral of iron 本论文主要以滇池现代沉积物为研究对象,对滇池现代沉积物的主要物理和化学性质(包括氨氮、有效磷、磁化率等) ,进行基础性地分析研究并对滇池现代沉积物铁的自生矿物进行了热力学分析。 |
| 8. | The pattern of diagenetic and porosity evolution are established . the primary porosity of the reservoir rocks was 35 % , which was reduced by 21 . 7 % by compaction and pressure solution and 8 . 2 % by cementation . the secondary pores were produced by organic acids " dissolution during organic matter maturing stage , resulting an increase of porosity by 5 % 预测本区砂岩原始孔隙度为35 ,经机械压实和化学压溶作用孔隙度损失了21 . 7 ,后经自生矿物的胶结作用,孔隙度损失了8 . 2 ,当进入有机质成熟阶段,有机酸的溶解作用产生次生孔隙,使孔隙度增加5 ,现今保存的平均孔隙度为10 . 1 。 |
| 9. | According to the thermodynamics analysis of spontaneous mineral of iron , we assumed : when sewage disposal , if sulphur is eliminated prior , this makes the consistency of iron ' s ion keep high relatively , it will react with phosphorus , produce heterosite , vivianite precipitate . this will decrease the interior load of the phosphorus in sediment , and reduce the consistency of the phosphorus in the dianchi lake 根据铁的自生矿物的热力学分析,提出设想:如果在污水处理时,优先脱硫,就使铁离子的浓度保持较高,与磷生成磷铁矿、蓝铁矿沉淀,就可以减轻沉积物中磷的内源负荷,进而降低滇池湖水中的磷的浓度。 |
