| 1. | The sediments are detrital . 沉积岩为碎屑质。 |
| 2. | The sediments are detrital and largely of greywacke facies . 沉积岩为碎屑质,大部分属于杂质砂岩相。 |
| 3. | Glauconite, detrital carbonate skeletal debris, marine fossils, and collophane are commonly present . 海绿石、碳酸盐骨骸碎屑、海相化石和胶磷矿普遍出现。 |
| 4. | The utilization of detrital carbon, whether autochthonous of allochthonous, may be important in the total metabolic system of lakes . 碎屑碳的利用,无论是资源的或他源的在湖泊的总代谢系统中都可能是重要的。 |
| 5. | Geochemical characteristics of cretaceous detrital rocks and their constraint on provenance in jixi basin 鸡西盆地白垩纪碎屑岩地球化学特征及其对物源的制约 |
| 6. | 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 |
| 7. | 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。 |
| 8. | In the older rocks below these glacial deposits are detrital uraninite and pyrite , two minerals considered evidence for very low levels of atmospheric oxygen 这些冰河沉积物下方的较老岩层,是沥青铀矿与黄铁矿碎屑;这两种矿物被认定为大气中氧气极为稀少的证据。 |
| 9. | Between diagenetic and detrital illites , alkylammonium reacts with detrital illite first . some other approaches such as vacuum encapsulation are applied , which improve the effect of dating 用上述两种方法获得的油气运移和成藏年龄,不仅具有重要的科学意义,也能带来巨大的经济效益。 |
| 10. | The contamination of detrital illite hinders the direct application of isotope ages . in order to separate authegenic illite from detrital , iaa and alkylammonium methods are performed in illite separating 碎屑伊利石往往与自生伊利石共生,导致样品的年龄远远大于自生伊利石的真实年龄。 |
