Clastic Sedimentary Rocks CliffsNotes

Clastic sedimentary rocks are classified according to the grain size of the sediment and the kinds of rock fragments that make up the sediment (Table ).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.

Shale is a finegrained sedimentary rock that forms from the compaction of silt and claysize mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as "mudstones." Shale is distinguished from other mudstones because it …

Rock (geology) Wikipedia

The proportion of silica in rocks and minerals is a major factor in determining their names and properties. Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size.

Soils Part 2: Physical Properties of Soil and Soil Water

A close look at soil will clearly indicate that the makeup of the mineral portion is quite variable. The soil is composed of small particles. These small particles are the result of massive rocks of different mineralogy that have weathered to produce smaller rock fragments and finally soil particles.

Particle Wikipedia

In the physical sciences, a particle (or corpuscule in older texts) is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass. They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials.

Sedimentary Rocks Tulane University

Sedimentary Rocks. Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation.

10(f) Characteristics of Sedimentary Rocks

Most sedimentary rocks are formed by the lithification of weathered rock debris that has been physically transported and deposited. During the transport process, the particles that make up these rocks often become rounded due to abrasion or can become highly sorted.
