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

有利圈闭为、构造、块及类型。

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

同时指出风暴发育区是良好或构造一圈闭区。

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

通过录井资料中积物类型及其叠加特征可以反推相对可容间的变化幅度。

4.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组合特征、体结构类型和岸坡结构类型。

5.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.

为砂、页-灰，积环境以滨岸潮坪为主，下部沼泽发育。

6.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.

积金矿床的矿体是一些不连续的内生或后生地质体,通常赋存于裂带、角砾体或(单位)中。
