Recognition of Sedimentary Rock Occurrences in Satellite and Aerial Images of Other Worlds—Insights from Mars [PDF]

Remote Sensing, 2021
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,

Silicic volcanism on Mars evidenced by tridymite in high-SiO2 sedimentary rock at Gale crater. [PDF]

Proc Natl Acad Sci U S A, 2016
Significance Tridymite, a SiO2 mineral that crystallizes at low pressures and high temperatures (>870 °C) from high-SiO2 materials, was detected at high concentrations in a sedimentary mudstone in Gale crater, Mars.

The Age and Erosion Rate of Young Sedimentary Rock on Mars [PDF]

Planetary Science Journal 3 246 (2022), 2022
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 using a one-parameter model based on the crater size-frequency distribution function with existing ...

Seasonal melting and the formation of sedimentary rocks on Mars, with predictions for the Gale Crater mound [PDF]

, 2012
A model for the formation and distribution of sedimentary rocks on Mars is proposed. The rate-limiting step is supply of liquid water from seasonal melting of snow or ice. The model is run for a O(10^2) mbar pure CO2 atmosphere, dusty snow, and solar luminosity reduced by 23%.

A Growth Model for Porous Sedimentary Rocks [PDF]

, 1997
A growth model for porous sedimentary rocks is proposed, using a simple computer simulation algorithm. We generate the structure by ballistic deposition of particles with a bimodal size distribution. Porosity and specific surface area are calculated varying the proportion of small and larger particles.

Quantitative Analysis of Experimental and Synthetic Microstructures for Sedimentary Rock [PDF]

, 1999
A quantitative comparison between the experimental microstructure of a sedimentary rock and three theoretical models for the same rock is presented. The microstructure of the rock sample (Fontainebleau sandstone) was obtained by microtomography. Two of the models are stochastic models based on correlation function reconstruction, and one model is based

Rupture cascades in a discrete element model of a porous sedimentary rock [PDF]

Phys. Rev. Lett. 112, 065501 (2014), 2014
We investigate the scaling properties of the sources of crackling noise in a fully-dynamic numerical model of sedimentary rocks subject to uniaxial compression. The model is initiated by filling a cylindrical container with randomly-sized spherical particles which are then connected by breakable beams.

Depositional environment of Jurassic deposits in the Binalud basin, according to the provenance and paleo-tectonic setting, northwest of Mashhad, Iran [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2021
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.
