Match the environmental depositional shift to its correct description.

Sedimentary rocks are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle in place.Names of Rocks in Trays (Underline the rocks on p.42-43) Sedimentary rocks listed in black are clastic sedimentary rocks. Those listed in blue are chemical sedimentary rocks. Breccia (consists of coarse, angular grains w/poor sorting) Conglomerate (coarse, rounded grains w/poor sorting)These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff. Pictures and brief descriptions of some common igneous rock types are shown on this page. Dacite is a fine-grained, extrusive igneous rock that is usually light in color. It has a composition that is intermediate between rhyolite and andesite.

Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic material. There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Metamorphic Rocks: Photos, descriptions and facts about foliated and non-foliated metamorphic rocks.

Shale is a rock composed mainly of clay-size mineral grains. These tiny grains are usually clay minerals such as illite, kaolinite, and smectite. Shale usually contains other clay-size mineral particles such as quartz, chert, and feldspar. Other constituents might include organic particles, carbonate minerals, iron oxide minerals, sulfide ...Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the “Earth’s Minerals” chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure below. The evaporite, halite, on a cobble from the Dead Sea, Israel.Use this printable infographic to learn about the rock cycle. There are three main types of rocks: sedimentary, igneous, and metamorphic.

Sedimentary Rock # 1. Arkose: This is a sedimentary rock with a high feldspar content (usually orthoclase or microcline), derived from weathering of feldspar-rich rocks like granites and gneisses. It contains some rock fragments and micas in a fine grained matrix. Red colouration is caused by the presence of hematite and iron staining.blocks, and bombs) and list in decreasing order after rock name. Preceed rock name with the term "welded" for pyroclastic rocks which retained enough heat to fuse after deposition. Rock names for such deposits are usually selected from the lower right portion of the classification diagram above. (Modified from Fisher, 1966rock fragments; fossils (e.g. fossiliferous limestone) ooliths; pellets; In contrast, the chemically-precipitated limestones consist solely of crystalline carbonates (e.g. microcrystalline limestone). The clastic limestones can be further subdivided according to their grainsize, much like other clastic sedimentary rocks. Other chemical ...Fine-Grained Clastic Rocks. Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row). If a mudrock shows evidence of fine layers (laminations) and breaks into sheets, it’s called shale.Otherwise, it’s siltstone (dominated by silt), mudstone (a mix of silt and clay), or claystone (dominated by clay). The fine-grained …Igneous rock, any of various crystalline or glassy rocks formed by the cooling and solidification of magma, which is a hot (600 to 1,300 °C, or 1,100 to 2,400 °F) molten or partially molten rock. Igneous rocks constitute one of the three principal classes of rocks, the others being metamorphic and sedimentary.Detrital Sedimentary Rocks.
