Mixed sedimentation is mainly a phenomenon by which siliciclastic and carbonate are mixed under a similar sedimentary environment. The study of the composition of mixed rock can reflect the sedimentary environment.

Mars sedimentary rock erosion rates constrained using crater counts, with applications to organic matter preservation and to the global dust cycle [PDF]
Small-crater counts on Mars light-toned sedimentary rock are often inconsistent with any isochron; these data are usually plotted then ignored. We show (using an 18-HiRISE-image, >10^4 crater dataset) that these non-isochron crater counts are often well-fit by a model where crater production is balanced by crater obliteration via steady exhumation.

A preliminary study on the Earth’s evolution and condensation
Through many field geology observations, the authors find that sandstone and carbonate rocks, which were originally thought to be sedimentary, have magmatic characteristics and should classified as magmatic rather than sedimentary rocks.

A Study on Rock Mass Classifications and Tunnel Support Systems in Unconsolidated Sedimentary Rock
This paper presents new valuable field data and a comprehensive approach to the determination of the rock mass classification and tunnel support systems for tunnels in unconsolidated sedimentary rocks as a special soil condition.

Evolution of major sedimentary mounds on Mars [PDF]
We present a new database of $>$300 layer-orientations from sedimentary mounds on Mars. These layer orientations, together with draped landslides, and draping of rocks over differentially-eroded paleo-domes, indicate that for the stratigraphically-uppermost $\sim$1 km, the mounds formed by the accretion of draping strata in a mound-shape.

The shale oil and gas exploration potential of the Jurassic Qianfoya Formation in the Sichuan Basin is promising. However, there is still a lack of understanding regarding the basic sedimentary characteristics and development patterns of fine-grained ...
