Regoliths are formed from the erosion of rock and it's transportation to a site where it resides temporarily, geologically speaking.
Regoliths and boulders.
A sedimentary rock is formed by the gradual and contineous accumulation, stratification, compactation, sedimentation, cementation, and lithification of transported and deposited debrises, detrituses, regoliths and other earths disintegrated materials, over a long period of time.
Ridges, rilles, craters and regoliths
Levees and regoliths.
Regoliths in the Alluvium subcategory, that is loose rocks and soils which cover a layer solid rocks, found on the ocean floor are in part the result of glacial rafting. As a glacier calves into the ocean, it creates ice burgs. Because glaciers are so erosive, they often carry pieces of broken rock within their ice. As they float out to sea, they melt, and drop any debris that they are carrying. These form regoliths known as "drop stones" on the ocean floor, and are indicative of cold conditions. Alluvium may also be from volcanic activity, turbidite, or other weathering events. Rocks exposed on the ocean floor, that are not regoliths, can indicate the direction of magnetic north when that rock formed.
Sandstone often contains sedimentary structures such as cross-bedding, ripple marks, and mud cracks that indicate deposition in a shallow water or terrestrial environment. Additionally, the presence of rounded grains in sandstone suggests abrasion and transport by water or wind, supporting the theory that it formed at the Earth's surface.
it was formed by being formed
