1·Organic materials were deposited in sequences of sandstone and mudstone, which were then covered by limestones as the environment became progressively more Marine.
无机矿物质按照砂岩和泥岩的顺序沉积着，并随着周围的自然环境演变为海洋性，由石灰石覆盖在了最上层。
2·Low compressive strength of the soft formation, such as mudstone, gypsum, gypsum, soft shale, soft limestone, sandstone.
低抗压强度的软地层，如泥岩。石膏。盐岩。软页岩。软石灰岩。砂岩。
3·The caprock of the hard Slick Rock Member of the Entrada Sandstone is perched upon a pedestal of mudstone.
在硬盘斯利克罗克成员恩特拉德砂岩盖层是建立在对泥岩座栖息。
4·At other hand, the golden content of the sandstone is higher than that of fine grain siltstone and mudstone, and tends to decrease and stabilize upward in the turbidite sequence.
另外，砂质单元金含量比细粒的粉砂岩和泥岩要高，从浊积岩序列的底部旋回至上部回金的含量降低并由不稳定到稳定等规律。
5·The variety of these mudstone and shales is very complex in lacustrinehigh-frequency cycle.
这些泥岩和页岩在湖相高频旋回中的变化相当复杂。
