岩性

Rich hydrocarbon accumulation area is usually associated with structure-lithology trap, fault trap and lentoid sand trap.

有利圈闭岩、构造岩、断块及断层。

Sedimentary structures of the storm deposits are:a)hummocky crossstratification are characterized by gentlly curved, low angel cross-lamination.

时指出风暴岩发育区是良好岩或构造一岩圈闭区。

The sediment types and their superimposed features in log data can conversely verify the rangeability of relative accommodation space.

通过录井岩资料中沉积物及其叠加特征可以反推相对可容间的变化幅度。

The main controlling factors of embankment slope stability are engineering geological petrofabric,rockmass structure type and structure of embankment.

在岸坡稳定分析评价中,控制岸坡稳定的主要因素有岸坡岩组合特征、岩体结构和岸坡结构。

The lithologies are dominated by alternating sandstones, shales and limestone, and the sedimentary environment based on shoreland tidal flat with swamp developed in the lower.

岩、页岩-灰岩互层，沉积环境以滨岸潮坪主，下部沼泽发育。

Orebodies in sedirmentary rock hosted Au deposits are discrete hypogene and epigenetic masses usually hosted in a fault zone, breccia mass, or lithologic bed or unit.

沉积岩金矿床的矿体是一些不连续的内生或后生地质体,通常赋存于断裂带、角砾岩体或岩层(岩单位)中。
