6.1 Clastic Sedimentary Rocks A clast is a fragment of rock or mineral, ranging in size from less than a micron 1 too small to see to as big as an apartment block. Various types of clasts are shown in Figure 5.3.1 and in Exercise 5.3. The smaller ones tend to be composed of a single mineral crystal, and the larger ones are typically composed of pieces of rock.

    Alkali feldspar granite, some varieties of which are called red granite, is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar K-spar. It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue peppered with minor amounts of.

    Other sandstones are a mixture of feldspar, quartz, clay, and small fragments of lithics, dark-appearing minerals and rock fragments, which represent mineralogically immature sediments. Such sandstones are technically known as lithic wackes, although geologists often call them by their old name, graywackes, and the rocks are sometimes.

    SEDIMENTARY ROCK TEXTURES. In clastic sediments the sedimentary texture includes the grain size, rounding, and sorting of the grains, all of which are related to what happened to the sediment during the weathering-to-deposition process.Because the processes that lead to the formation of chemical sedimentary rocks do not involve the weather-to-deposition process, there is no widely agreed-upon.

    Whereas the bulk of minerals making up clastic sedimentary rocks are common rock-forming species, such as quartz, feldspar and mica, both common and minor minerals in an eroding rock may end up in the resulting sediment. Minerals that have been transported as detrital grains, to end up in a sedimentary rock, are referred to as allogenic.

    Quartz is the most stable and has the greatest resistance to the mechanical and chemical abrasion during erosion, so most sand size grains are quartz. Feldspar alters to clay with chemical weathering and erosion, so arkose, which is sandstone with more than 25 feldspar, indicates the sediment was deposited close to the source rock and was not.

    2 As a result though a mineral may be broken out of its surrounding rock-say a grain of quartz or feldspar from a granite rock-no new substance is formed. On the contrary, chemical weathering frequently results in the formation of new minerals, since percolating waters may produce rearrangement of constituent ions or may add or remove substances.

    2 Thus, of the eight common igneous minerals, only quartz, K-feldspar, and muscovite are commonly seen in sedimentary rocks. These minerals are joined in sedimentary rocks by clay minerals, calcite, dolomite, gypsum, and halite. The clay minerals form during mineral weathering. The other four minerals are salts that precipitate as water evaporates.

    What is quartz made of Quartz is an igneous rock made out of molecules of silicon and oxygen atoms held together in a crystal pattern. All of the silica and oxygen that make quartz came originally from the insides of stars, and it shot out of the stars when the stars exploded as supernovas.Then the silica formed part of a nebula, a dust cloud floating in space.
