What is Oligomictic conglomerate?
1. A conglomerate containing clasts of only a few different rock types.
What is Polymict conglomerate?
(also polymictic) Geology. (of a conglomerate) consisting of fragments of several different rock types. ‘polymict eucrites’ ‘Most bodies consist of monomict gabbro breccia resting directly on polymict conglomerate.
What is Intraformational conglomerate?
[¦in·trə‚fȯr′māsh·ən·əl kən′gläm·ə·rət] (geology) A conglomerate in which clasts and the matrix are contemporaneous in origin. A conglomerate formed in the midst of a geologic formation.
What type of sedimentary rock is conglomerate?
Conglomerate is a sedimentary rock made of rounded pebbles and sand that is usually held together (cemented) by silica, calcite or iron oxide. It is a stone similar to sandstone but the rock particles are rounded or angular gravel rather than sand.
What is the difference between a breccia and a conglomerate?
A clastic rock made of particles larger than 2 mm in diameter is either a conglomerate or breccia. A conglomerate has rounded clasts while a breccia has angular clasts. The highly angular boulders and cobbles again indicate a breccia.
Why are conglomerates poorly sorted?
The poorly sorted conglomerates have a matrix of clay or sand. The abundance of unstable minerals with poor sorting indicates rapid mechanical erosion and deposition, as in alluvial fans or in density currents (i.e., highly turbid bottom currents) resulting from gravity flows.
Is conglomerate mature or immature?
Conglomerate is an immature sedimentary rock, with a poorly sorted mixture of clay, sand, and rounded pebbles (gravel-sized) (Figure 11.18). The mineralogy of the clasts (sand and pebbles) varies depending on the original source rock.
What is difference between Orthoconglomerate and Paraconglomerate?
The differences between paraconglomerates and orthoconglomerates reflect differences in how they are deposited. Paraconglomerates are commonly either glacial tills or debris flow deposits. Orthoconglomerates are typically associated with aqueous currents.
What is an example of a conglomerate business?
Real World Examples Examples of conglomerates are Berkshire Hathaway, Amazon, Alphabet, Facebook, Procter & Gamble, Unilever, Diageo, Johnson & Johnson, and Warner Media. All of these companies own many subsidiaries.
What is the source rock of conglomerate?
Conglomerate (/kənˈɡlɒmərɪt/) 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.
How is breccia created?
Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan.
