In some areas dropped stones are found finely ...Turbidites are deposited from slurries of sediment and water in any standing body of water (lakes, oceans). They can occur in any layer of a water body (near surface, benthic) as long as there is an oversteepened slope. The fluid involved is water, which mixes with sediment. The new sediment and water mixture is denser than the surrounding ...

Rocks are mainly of three types. The change of one rock into another type is known as one rock cycle. Sedimentary rocks are formed from the material obtained by the erosion of Igneous rocks.

An early evidence of one such titillate can be observed in the southern portion of the Atlantic ocean that also provides evidence of continental drift. Two types of till are identified, namely 1.

Sedimentary Rocks. Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth’s surface.Rocks become finer grained and more schistose and the unit becomes thicker toward the southwest, where there is included an isolated subunit which may be a tillite, consisting of cobbles, boulders, and blocks of argillite and carbonate rocks in a fine silty matrix. In any event, the diversity of igneous and metamorphic lithologies within the Sheehan Tillite Member indicates that the clasts were not derived from the Bolla Bollana Tillite, because the Mt Painter and Mt Babbage inliers (the potential source for the crystalline rocks) were covered at the time of deposition of the latter glacial unit (Preiss ...Several features are visible, including sedimentary bedding (gray and tan), mineral veins (orange, perpendicular to bedding; and white, diagonal to bedding), and glacial striations.

In the west is the Zeehan Tillite. The broken fragments of rocks are often faceted and scratched, and can be up to boulder sized. They are embedded in rock flour and silt. The ice that brought the till flowed from the west of Tasmania in an easterly direction. The tillite may have started appearing in the Late Carboniferous. Later the result of this weathering came to the surface resulting in some truly unique looking rock formations. 2. Desquamation – physical weathering. Physical weathering is caused by flat, shell moulded plates that have burst off the rocks due to temperature changes. This can be found fairly easily around the farm house. 3.It is this sequence of deposition that creates the Bouma sequences that characterize these rocks.
