| 1. | Parent material, whether residual or transported, is the basis of all soils .
母岩物质无论是残积的，或是搬运的，是所有土壤的基础。 |
| 2. | Kerogen analyses, however, require preliminary isolation of the kerogen by hydrochloric and hydrofluoric destruction of the inorganic minerals .
但是，油母岩分析需要使用盐酸和氢氟酸破坏无机物以便初步分离出油母岩。 |
| 3. | Effects of soil - forming rocks and sprout ages on the bark quality of pteroceltis tatarinowii
成土母岩和条龄对青檀檀皮质量的影响 |
| 4. | Among these , yellow soil account for 80 % of the total area soil depth has negative relation with slope
土层厚度与坡度呈负相关，而在母岩倾角大的地带，由于坡度大的增大以薄层土壤居多。 |
| 5. | Once formed , zircon crystals are so durable that they can persist even if their parent rock is exposed at the surface and destroyed by weathering and erosion
但是，这些锆石所蕴含的讯息似乎隐晦不清，部份原因是地质学家无法确定它们的母岩。 |
| 6. | Most soils in pakistan are derived from water - transported ( alluvium ) or wind - blown ( loess ) material , yet some have been formed by in - situ weathering of rocks
巴基斯坦大多数土壤由水成（冲积）或风成（黄土）母质发育而来，也有一些是当地母岩风化而成。 |
| 7. | There is a closely retationship between the formation of gold deposit and the tectonics , stratigraphy , petrological character , intrusive rocks , uolcanic rocks and ductile shear zone
中酸性火山岩是本区主要成矿母岩，韧脆性剪切带是金矿形成的重要导矿构造。 |
| 8. | The third - deepest soil zone in abc soil , unaltered by weathering and made up of the parent rock from which the two uppermost layers derive as well as other mineral materials
剖面层abc土壤剖面层中深度排第三的剖面层，不受风化的影响，由上两层及其他矿物组成的母岩所构成 |
| 9. | The zircons we studied were depleted in oxygen 18 relative to the mantle , and such depletion occurs only if the crystals formed from rocks that interacted with rain or snow
因为相较于地函，我们所研究的锆石，氧18含量偏低，而这种情形只有可能是晶体的母岩曾经和雨水或雪发生交互作用。 |
| 10. | The feldspathic sandstones belong to this formation of composite sources metamorphic , sedimentary , and igneous sources , but mainly from metamorphic source due to the high abundance of brown cl colors of quartz
上述情况表明，研究区长石砂岩物源母岩包括变质岩、沉积岩与火成岩，但从发育大量棕色石英颗粒来看，物源以变质岩为主。 |
