Sedimentary rocks provide records of past surface and subsurface processes and environments. The first step in the study of the sedimentary rock record of another world is to learn to recognize their occurrences in images from instruments aboard orbiting,

The Age and Erosion Rate of Young Sedimentary Rock on Mars [PDF]
The Medusae Fossae Formation (MFF) is an enigmatic sedimentary unit near the equator of Mars, with an uncertain formation process and absolute age. Due to the heavily wind-eroded surface, it is difficult to determine the absolute model age of the MFF ...

Early thinning, late persistence, diachronous boundaries, and a regional dichotomy in Mars' young sedimentary rocks [PDF]
Mars’ sedimentary rocks record Gyrs of environmental change. New data enable global analyses of paleo-environment relevant physical properties of these rocks, including layer thickness and accumulation rate.

Natural Radioactivity Measurements and Radiation Dose Estimation in Some Sedimentary Rock Samples in Turkey [PDF]
The natural radioactivity existed since creation of the universe due to the long life time of some radionuclides. This natural radioactivity is caused by γ-radiation originating from the uranium and thorium series and 40K.

Depositional environment of Jurassic deposits in the Binalud basin, according to the provenance and paleo-tectonic setting, northwest of Mashhad, Iran [PDF]
The thick Jurassic fluvial coarse-grained sediments rest non-conformably on older metamorphic rocks to the northwest of Mashhad. Two sections, 300 and 400 m thick, were measured and studied through the Jurassic deposits.

Study on sedimentary facies characteristics of Xujiahe Formation in Sichuan Basin [PDF]
Sedimentary facies is the summation of all primary sedimentary features in a sedimentary unit, which is the product of sedimentation in a specific environment. It emphasizes the material performance of sediment formation conditions, including mineralogy,
