| 1. | This lagoon "divider" consist of sand . 泻湖这个“分水岭”是由砂质物构成的。 |
| 2. | The sand forms a continuous transgressive blanket . 砂质物构成一个连续的海进盖层。 |
| 3. | There is sufficient sand available to blanket the unconformity . 这里有充足的砂质物铺盖不整合面。 |
| 4. | Thin layers of sandy shale, and carbonaceous fragments are locally present . 局部出现砂质页岩薄层和碳质碎屑。 |
| 5. | Magnesium deficiency most commonly occurs in acid, sandy soils in areas of moderate to high rainfall . 缺镁常常发生在中雨量或高雨量区的酸性砂质土。 |
| 6. | This sandstone unit is commonly thick-bedded and massive, with silty and carbonaceous laminations . 该砂层单元通常为厚层或块状,具粉砂质和碳质纹层。 |
| 7. | In fact, the available sand is insufficient to form a continuous blanket overlying the unconformity . 事实上,所补入的砂质物不足以在不整合面上形成连续的盖层。 |
| 8. | The thickness of this sheet sandstone is related directly to rate of regression and the amount of sand available . 这种席状砂岩的厚度直接取决于海退速率以及砂质供给量。 |
| 9. | The sand carried outside the bar is spread out over the slope by the expanding head of the rip current . 从砂洲外面搬出去的砂质物,在急流的汹涌水头作用下被展布于整个斜坡上。 |
| 10. | The growth of these bars is limited by the depth at which waves will plunge and prevent further sand encroachment . 这些砂洲的生长仅限于波浪能冲进的深度,并且阻挡了外边砂质物的进入。 |
