Coarse sandstone
Jan 23, 2019 · Sandstone is a clastic sedimentary reservoir rock composed of mainly quartz and/or feldspars, and typically deposited by relatively high-energy processes, which winnow out much of the fine particle size fraction while transporting and depositing the coarser (sand-sized) particles. The upper Moscovian Illinka sandstone is very coarse and poorly-sorted, but shows well-developed current-induced large-scale cross-bedding. The basal and top parts of the sandstone show slightly ...
