Grain size is largely a function of the distance the particle was transported. In general, the greater the distance traveled, the smaller and more rounded the sediment particles will be.

Rock gypsum can be easily scratched with a fingernal Chemical rocks are made of fragments of pre-existing rocks c. A siltstone and a ciaystone can be distinguished by licking or chewing the rock d Carbonate rocks react to acid e The most important property in identifying a clastic rock is grain size Question 4 How can you distinguish a chert ...Detrital Rocks • Detrital Sedimentary Rocks ‐ material mainly classified on grain size & composition in the sandstones Examples: Conglomerate (rounded gravels/poorly sorted with gravels to clays etc.)‐can indicate steep slopes, strong currents or glacial origin Sedimentary Breccia(angular gravels/poorly sorted)‐indicates that material did not travel farThe specific gravity of gypsum grains is about 2.32 (Kifae 2010), which is significantly smaller than those of soil solid grains (Gs) which typically varies within a range of 2.6 to 2.8. Therefore, it is expected that in situ soils containing gypsum crystals will have smaller grain specific gravity as gypsum crystal content increases.34.Which symbol represents the sedimentary rock with the smallest grain size?

7) Because of its rock cleavage, slate makes a better roofing material than rock gypsum. 8) Coal is a sedimentary rock that is made of organic matter. 9) Mud cracks and ripple marks are common features of igneous rocks. 10) Compaction and cementation are the most common forms of lithification.Table 4-1.—Igneous and metamorphic rock grain size descriptors Descriptor Average crystal diameter Very coarse-grained or pegmatitic Coarse-grained Medium-grained Fine-grained Aphanitic (cannot be seen with the unaided eye > 10 mm (3/8 in) 5-10 mm (3/16 - 3/8 in) 1-5 mm (1/32 - 3/16 in)Lithographic limestone is a dense rock with a very fine and very uniform grain size. It occurs in thin beds which separate easily to form a very smooth surface. In the late 1700s, a printing process known as lithography (named after the stones used) was developed to reproduce images by drawing them on the stone with an oil-based ink, then using ... ….

In the rare cases where natural gypsum was used for tests, the gypsum was crushed, sieved and washed before compacting the fractions with a known grain size to form the test samples (De Meer and Spiers, 1995). The overall properties of the samples so obtained are expected to be closer to gypsum rock than to synthetic gypsum.Grain Size: Very Fine Sand Shape: Rounded Sorting: Well Components: Chemical Minerals/Rock Fragments present (Approximate %): Gypsum Rock History: Water/River (Fluvial) Clues to Identify: Clear to whitish-pale gray or pinkish; soft, can be scratched with a fingernail
