Modern carbonate sediments are generated in a variety of environments: continental, marine, and transitional, but most are marine.Alice Springs Orogeny: The Alice Springs orogeny was an intraplate orogeny, meaning it occurred within a tectonic plate rather than at the edge as a result of a collision with another tectonic plate. It was a slow process that occurred over 150 million years from 450

Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.

Nov 17, 2021 · They are usually located at or near where the land meets the sea. Transitional sandstone environments include deltas beaches, lagoons, tidal flats, salt marshes, and barrier islands. Delta is a sandstone marine depositional environment located at the mouth of a river. Possible cross-beds and ripple marks characterize it. They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow sea floor.
