This void space consists of pore space between grains or crystals, in addition to crack space.
Well-sorted indicates a grain size distribution that is fairly uniform.
geotechnical engineers examine the nature and behaviour of the materials on, in, or of which such structures as buildings, dams, tunnels, bridges, and underground storage vaults are to be constructed; reservoir engineers analyze the response measured on well logs or in the processes of deep drilling at elevated temperature and pressure. The pore-filling fluid is usually briny water, often indicative of the presence of seawater when the rock was being deposited or lithified.
Since rocks are aggregates of mineral grains or crystals, their properties are determined in large part by the properties of their various constituent minerals. It should be noted that the bulk density is less than the grain density of the constituent mineral (or mineral assemblage), depending on the porosity.
Most are deposited from the land surface to the bottoms of lakes, rivers, and oceans.
Sedimentary rocks are generally stratified—Metamorphic rocks are those formed by changes in preexisting rocks under the influence of high temperature, pressure, and chemically active solutions.
The rock cycle illustrated in Diagenesis is, as previously explained, the process of forming sedimentary rock by compaction and natural cementation of grains, or crystallization from water or solutions, or recrystallization.
The conversion of sediment to rock is termed Rocks have many different textures.
In contrast, obsidian tends to have a smooth glassy feel, whereas serpentine may feel platy or fibrous, and talc schist often feels greasy.
On the other hand, the texture of gneiss is often described by its distinct banding.
Depending on the type of close-packing of the grains, porosity can be substantial.
It should be noted that in engineering usage— Total porosity encompasses all the void space, including those pores that are interconnected to the surface of the sample as well as those that are sealed off by natural cement or other obstructions.
Analysis of texture can yield information about the rock’s source material, conditions and environment of deposition (for sedimentary rock) or crystallization and recrystallization (for igneous and metamorphic rock, respectively), and subsequent geologic history and change.
