| 1. | There are four principal types of limestones . 石灰岩有四种主要类型。 |
| 2. | The channel is overlain by siltstone and lenticular beds of limestone . 河道上面覆盖着粉砂岩和石灰岩透晶体。 |
| 3. | A thin, resistant limestone escarpment is present just basinward . 薄层状的坚硬的石灰岩山崖正好位于靠盆地一侧。 |
| 4. | The isotopic signatures of most ancient limestones indicated the same process . 大多数古代石灰岩的同位素特征说明了同样的过程。 |
| 5. | Calcareous sediments accumulated on a sea floor and eventually were compacted and cemented to form limestone . 钙质沉积物堆积在海底,最后压紧并胶结形成石灰岩。 |
| 6. | This characteristic has been shown to be particularly true in limestone areas where cracks and crevices occur . 在有断裂和裂隙的石灰岩区域,这种物性表现得特别清楚。 |
| 7. | Material illustrating detailed structure of graptolites has been etched from limestone by means of hydrofluoric acid . 表明笔石详细构造的物质是利用氢氟酸从石灰岩中侵蚀出来。 |
| 8. | Dolomite also occurs in this mode as replacement of limestone along major fractures and belts of enclosed breccia . 沿包围角砾岩的主要裂隙带,以交代石灰岩的方式,也能形成白云石。 |
| 9. | Chemical analysis of limestons for free silica 石灰岩中游离二氧化硅化学分析方法 |
| 10. | Determination of total organic carbon in limestone 石灰岩中有机碳总量的测定 |
