Clastic vs crystalline.

Primary porosity in clastic and some carbonate rocks (such as oolites) is a function of grain size, packing, shape, sorting, and amount of intergranular matrix and cement. [8] In theory, porosity is independent of grain size. Changes in grain size, however, affect grain shape and sorting.Only some sedimentary rocks have a clastic texture. It is essential that you are able to recognize these textures (Figure A). They form the major division between many rocks. Failure to differentiate between a crystalline versus a clastic texture could result in you being responsible for drilling through granite instead of sandstone! 1.Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that …View Notes - Geology Test Review from GEOL 1121K at Georgia State University. Test Review: Chapter 1: - Formation of universe - Age of universe - Age of earth - Heliocentric vs. geocentric model -Clastic rocks are classified based on their grain size. The most common clastic sedimentary rocks are shale (grains less than 1/256 mm in diameter), siltstone (1/256 mm-1/16 mm), sandstone (1/16 mm-2 mm), and conglomerate (greater than 2 mm). Chemical or crystalline sedimentary rocks form from mineral solutions.

There is some overlap between the two because almost all clastic sedimentary rocks contain cement formed from dissolved ions, and many chemical sedimentary rocks include some clasts. ...

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 sedimentary rocks. Other chemical sedimentary rocks include: banded-iron formations Sedimentary rock is classified into two main categories: clastic and chemical. Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. Limestone that consists of crystals of calcite or microcrystalline masses of calcite is called crystalline limestone. Alternatively, limestone can be formed biologically with the most …Chert is as hard as crystalline quartz with a hardness rating of seven in the Mohs scale — maybe a bit softer, 6.5, if it still has some hydrated silica in it. Beyond simply being hard, chert is a tough rock. It stands above the landscape in outcrops that resist erosion. Oil drillers dread it because it’s so hard to penetrate.

Textures of carbonate rocks are extremely variable. Textures can vary from those similar to clastic sediments, showing characteristic grain sizes, sorting, and rounding, to those produced by chemical precipitation. In carbonates the matrix can range from fine grained carbonate mud to crystalline calcite or dolomite.

Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock.

The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments.The clastic sediment is often referred to as “siliciclastic” because it is derived from the rocks of the crust which, as we have learned, is largely composed of silicate minerals of igneous rock. Clastic (or detrital) rock is classified and named based on the size and composition of the clasts.

1) Clastic -- discrete fragments cemented and compacted together; all detrital sedimentary rocks have clastic texture. 2) Nonclastic or crystalline -- minerals form a pattern of interlocking crystals. Clastic. Rocks with a clastic texture consist of discrete fragments and particles that are cemented and compacted together.
