Conglomerate (geology) - Wikipedia

Conglomerate is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. A conglomerate typically contain a matrix of finer grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form by the consolidation and lithificationof gravel. They can be found in sedimentary roc

Conglomerate - Sedimentary Rocks

Conglomerate is a sedimentary rock formed by the lithification of rounded or sub-rounded gravel (grains larger than 2 mm in diameter). Conglomerate is strongly related to sandstone.It is actually a type of sandstone, although it may not be technically correct to say so.

Mar 04, 2016  5.1 Conglomerate Composition as a Proxy of the Average Igneous Crust Composition at Gale Crater. Conglomerates provide information about igneous parent rocks at the source of the transported sediments, i.e., from the north rim of Gale Crater. Gale Crater's walls reach 3–4 km in height, suggesting exhumation of crustal rocks from that depth.

The erratic and low gold and uranium contents of the investigated pre-Witwatersrand conglomerates, to a large extent, is explained by the inefficiency of the operating sedimentary reworking processes. The detrital chromites of all studied conglomerates have an identical chemical composition which points to an origin from the same provenance areas.

Clastic rock - Wikipedia

Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering. Geologists use the term clastic with reference to sedimentary rocks as well as to particles in sediment transport whether in suspension or as bed load, and in sediment deposits.

Igneous Rocks Classified by Composition

Igneous rocks are classified according to their mineral content: Ultramafic rocks are dominated by olivine and/or pyroxene.; Mafic rocks are dominated by plagioclase and pyroxene (even if you can't see them with the naked eye) and smaller amounts of olivine.; Intermediate rocks are roughly even mixtures of felsic minerals (mainly plagioclase) and mafic minerals (mainly hornblende, pyroxene ...
