Only the treatments added with 40% green mudstone and 8% fly ash had no obvious effect on moisture content of potted media.

Except for the treatment adding 15% green mudstone, the other treatments promoted maize germination.

The igneous and mudstone fragments in the sandstones were attributed to the uranium resources.

The main rocks are sandstone, mudstone and muddy siltstone or silty mudstone.

The fractured mudstone reservoir with salt interbred is a special reservoir type.

In recent years, lots of reservoirs of thin sand and mudstone interbedding in Kailu area have high output.

and the Cretaceous marine mudstone and coal-bearing formations of transitional facies.

Using the ground-penetrating radar technology, the authors studied the strong punning effect of mudstone filling embankment.

The South Tianshan Basin and East Tarim Basin were siliceous rock-limestone-mudstone basin.

The variegated mudstone belongs to the Jurassic Xishanyao Formation and the Toutunhe Formation is generally absent in the Shinan area.

Wuytak Fm regression phase, the formation of variegated mudstone, siltstone sandstone and mudstone of tidal cream-supratidal sedimentary.

thick abnormal pressure mudstone in lower Tertiary is the cap, or "quilt" .

The cracky mudstone as well as may become reservoir.

In the zones deposited in the river to delta there are less abundance and the worse types in the source rocks like green grey mudstone.

The two main clay minerals in prodelta and lacustrine mudstone are illite and chlorite.

The thick mudstone can control the sealing features of traps.

Mudstone, muddy limestone and gypsum act as good seals.

In order to demonstrate the applicability of red-mudstone as subgrade bed filling, static and dynamic triaxial tests are performed.

and the seepage coefficient decreases when the mudstone content in rockfill increases.

Undercompaction mudstone appears in the Shuangyang Formation and it enhances the seal of oil-gas.

In other areas, the K1d2 mudstone cap-rock has good sealing ability.

Mudstone of Qingl member in Wangfu depression is the best oil source rock, Qing2 and Qing3 members are relatively poor oil source rock.

The results show that the creep rate of mudstone is not only related to stress state, but also to time.

Due to some reasons such as geological structure, usually there are mudstone interlayers in rock.

Mudstone geological conditions are distributed broadly in our country.
