Chemical Sedimentary Rocks form from the inorganic precipitation of minerals from a fluid. If the ions present within a fluid (water) become very concentrated either by the addition of more ions or the removal of water (by freezing or evaporation), then crystals begin to form. In this case, the identification of the type of sedimentary rocks is ... Rocks. There are three main categories of rocks, which are defined by how the rocks are formed. Sedimentary Rocks. Sedimentary rock is often found in layers. One way to tell if a rock sample is sedimentary is to see if it is made from grains. Some samples of sedimentary rocks include limestone, sandstone, coal and shale.

Three Types of Rock. Rocks fall into these three groups: Igneous , Sedimentary , and Metamorphic. Igneous rocks are formed from melted rock deep inside the Earth.

Rock identification is a systematic process, requiring concise, accurate descriptions of physical characteristics. This process is called petrography. Geologists use petrographic descriptions to communicate the essential features of rocks in writing (with illustrations / photographs if appropriate). Geologists working in the field carry a rock hammer, so they can break off the weathered, outer parts of rocks to see the “fresh,” unweathered rock inside. If you can see and identify the minerals in an igneous rock, you can gain further information about the igneous composition.

Some of the key characteristics are visible, but others rely on physical and chemical tests and knowing the rock’s origin. Color and Composition: Light-colored rocks (high in silica) suggest a felsic composition (e.g., granite, rhyolite).Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.. Igneous rocks can have many different compositions, depending on …
