Arenite

Index Arenite

Arenite (Latin Arena, sand) is a sedimentary clastic rock with sand grain size between 0.0625 mm (0.00246 in) and 2 mm (0.08 in) and contain less than 15% matrix. [1]

Arkose

Arkose is a detrital sedimentary rock, specifically a type of sandstone containing at least 25% feldspar.

Cleavage (geology)

Cleavage, in structural geology and petrology, describes a type of planar rock feature that develops as a result of deformation and metamorphism.

Erosion

In earth science, erosion is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth's crust, and then transport it to another location (not to be confused with weathering which involves no movement).

Grain size

Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.

Greensand

Greensand or green sand is a sand or sandstone which has a greenish color.

Greywacke

Greywacke or Graywacke (German grauwacke, signifying a grey, earthy rock) is a variety of sandstone generally characterized by its hardness, dark color, and poorly sorted angular grains of quartz, feldspar, and small rock fragments or lithic fragments set in a compact, clay-fine matrix.

Lamination (geology)

In geology, lamination is a small-scale sequence of fine layers (laminae; singular: lamina) that occurs in sedimentary rocks.

Limestone

Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs.

Lutite

Lutite is old terminology, which is not widely used, by Earth scientists in field descriptions for fine-grained, sedimentary rocks, which are composed of silt-size sediment, clay-size sediment, or a mixture of both.

Matrix (geology)

The matrix or groundmass of rock is the finer-grained mass of material wherein larger grains, crystals or clasts are embedded.

Metamorphic rock

Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form".

Modern Greek

Modern Greek (Νέα Ελληνικά or Νεοελληνική Γλώσσα "Neo-Hellenic", historically and colloquially also known as Ρωμαίικα "Romaic" or "Roman", and Γραικικά "Greek") refers to the dialects and varieties of the Greek language spoken in the modern era.

Pelite

A pelite (Ancient Greek pelos, clay) is a metamorphosed fine-grained sedimentary rock, i.e. mudstone or siltstone.

Psammite

Psammite (Greek psammos, sand) is a general term for sandstone.

Psephite

Psephite (psephos, pebble) is either a sediment or sedimentary rock composed of fragments that are coarser than sand and which are enclosed in a matrix that varies in kind and amount.

Rudite

Rudite is a general name used for a sedimentary rocks that are composed of rounded or angular detrital grains, i.e. granules, pebbles, cobbles, and boulders, which are coarser than sand in size.

Sandstone

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments.

Sedimentary rock

Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water.

Silicate

In chemistry, a silicate is any member of a family of anions consisting of silicon and oxygen, usually with the general formula, where 0 ≤ x Silicate anions are often large polymeric molecules with an extense variety of structures, including chains and rings (as in polymeric metasilicate), double chains (as in, and sheets (as in. In geology and astronomy, the term silicate is used to mean silicate minerals, ionic solids with silicate anions; as well as rock types that consist predominantly of such minerals. In that context, the term also includes the non-ionic compound silicon dioxide (silica, quartz), which would correspond to x.

Turbidite

A turbidite is the geologic deposit of a turbidity current, which is a type of sediment gravity flow responsible for distributing vast amounts of clastic sediment into the deep ocean.
