According to incomplete statistics, approximately 69% of the reservoir area suffered rockslide hazard during the impoundment of the Three Gorges Reservoir [10, 11], which is closely related to the rheological effect under water-rock interaction of the
mudstone formation.
[5] studied pore structure characteristics and permeability of seven types of deep sedimentary rocks (i.e.,
mudstone, sandy
mudstone, siltstone, fine sandstone, medium sandstones, coarse sandstone, and conglomerate) based on MIP measurement data.
The lowermost Ragavere Formation (Torremagi Member) is fine-grained, bioclastic wackestone and the upper part (Piilse Member) is composed of calcareous (lime-)
mudstone (cryptocrystalline limestone).
The Curiosity rover has already found proof of ancient lakes in older, lower-lying rocks on Mars, according to reports, as well as a
mudstone above Old Soaker.
This is particularly true when such structures are built in
mudstone and sandstone, which are two most widely distributed rock types encountered in underground mines.
By drilling into Martian
mudstone, the rover was able to identify thiophene, 2- and 3-methylthiophenes, methanethiol and dimethylsulfide that are all also present in Earth
mudstone.

Mudstone would be stored on this land in the next two years - with three proposed on the Grangetown Prairie site, two lined up on the Warrenby landfill area and one of the metals recov-ery site.
Wang said that most people know that mangoes grown in this area of Tainan, with its chalk soil and
mudstone, are the sweetest and most fragrant despite their smaller size, according to the news outlet.
Lithofacies include clast-supported massive boulder conglomerate (Gcm(a)), clast-supported massive cobble conglomerate (Gcm(b)), clast-supported pebble to cobble conglomerate (Gcm(c)), clast-supported pebble conglomerate (Gcm(d)), Matrix-supported pebble conglomerate (Gmm), trough cross-stratified pebbly sandstone (St), horizontally stratified sandstone (Sh), trough cross-stratified sandstone (St), ripple cross laminated sandstone (Sr), massive sandstone (Sm), siltstone (F), massive
mudstone (Fm), massive variegated
mudstone (Fmv).
For the study, 60 oil shale samples and 30 samples of other rocks (sandstone,
mudstone shale, dolostone, limestone) were collected from four drillings: S0501, S1403, S2503 and W7601 (Fig.
For the
mudstone study, Jennifer Eigenbrode (NASA Goddard) and colleagues heated pulverized rock to nearly 900[degrees]C (1,600[degrees]F), catching the gases released as the rock molecules underwent chemical reactions or broke down.
