Elemental geochemistry of sedimentary rocks at Yellowknife Bay, Gale crater, Mars.
Sedimentary rocks examined by the Curiosity rover at Yellowknife Bay, Mars, were derived from sources that evolved from an approximately average martian crustal composition to one influenced by alkaline basalts. No evidence of chemical weathering is preserved, indicating arid, possibly cold, paleoclimates and rapid erosion and deposition. The absence of predicted geochemical variations indicate...
متن کاملSedimentation and Sedimentary Rocks
Sedimentary rocks are one component of the modern threefold classification of rocks. They derive from the lithification of sediments, which are produced in basically two ways: by the mechanical deposition of grains derived from the alteration of other rocks (detrital or clastic rocks), or as chemical precipitates or grains formed organically or inorganically from an aqueous solution. The whole ...
متن کاملPattern formation in sedimentary rocks: Connectivity, permeability, and spatial correlations
Sedimentary rocks have complicated permeability patterns arising from the geological processes that formed them. We concentrate on pattern formation in one particular geological process, avalanches (grain flow) in wind-blown or fluvial sands. We present a simple experiment and numerical model of how these avalanches cause segregation in particle size that lead to characteristic laminated patter...
متن کاملHypotheses for the origin of fine-grained sedimentary rocks at Santa Maria crater, Meridiani Planum
En route to Endeavour crater, the Mars Exploration Rover Opportunity embarked on a short but significant campaign at Santa Maria crater during sols 2450–2551. Santa Maria crater is a relatively young impact crater, approximately 100 m in diameter and 11–17 m deep. Opportunity performed detailed analyses on several ejecta blocks and completed an extensive imaging campaign around the crater. Many...
متن کاملReliability assessment of Needle Penetration Index for estimating compressive strength of some sedimentary rocks from the Qom Formation, Central Iran
In this paper, the needle penetrometer test was utilized to explore the reliability of the Needle Penetration Index (NPI) for estimating the Unconfined Compressive Strength (UCS) of sedimentary rocks including gypsum, marl, siltstone and sandstone collected from the Qom Formation. Following the UCS and NP test, regression analyses were carried out to control the predictive performances of NPI. ...
