In general, the greater the flow, the more sediment that will be conveyed. Water flow can be strong enough to suspend particles in the water column as they move downstream, or simply push them along the bottom of a waterway 11.What is the name of the process that turned granite into sediment? Weathering and Erosion: 7. Over time, the sandy sediment has become a sedimentary rock called sandstone. What process turns sand into sandstone? Compacting and cementing: 8. Next, the sandstone gets pushed underground and transforms inti a metamorphic rock called quartzite. Fossil leaf fragments occur in all deep-water sandstone packages from the upper slope to the basin floor. Fossil leaf fragments were apparently carried into deep water by turbidity currents during lowstands of sea level. Within turbidite sandstones, fossil leaf fragments are concentrated in layers with up to 50 wt.% total organic carbon (TOC).formation.

Clastic sedimentary rocks are made from the fragments of eroded bedrock and sediment, which is usually derived from physical weathering.t. e. River discharging sediment into the ocean. Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. chancellor's merit scholarship The ancient sand dunes were similar to dunes in modern deserts, probably reaching several hundred feet at their greatest height. Only the bottom portion of a dune is preserved in the sandstone, but layer upon layer of dunes built up, until the total thickness of the pile of sand grew to be over 2,000 feet thick (although most of this thickness would have been underground).The channel sandstone is disconformable to the sediment of the underlying cyclothem. In stage 3, the cyclothem has gone through deep burial and subsequent uplift. It is once again proximal to the surface and is overlain by only a thin section of younger Pennsylvanian strata and a shallow veneer of Pleistocene sediment.
