Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. It takes a strong water current to transport and produce a rounded shape on particles this large. ... Conglomerates often begin when a sediment consisting mainly of pebble- and cobble-size clasts is being deposited.
How do you identify a conglomerate rock?
The key characteristic of conglomerate is the presence of readily visible, rounded clasts bound within a matrix. The clasts tend to feel smooth to the touch, although the matrix can be either rough or smooth. The hardness and color of the rock is highly variable.Jun 15, 2018
What is the description of conglomerate?
conglomerate, in petrology, lithified sedimentary rock consisting of rounded fragments greater than 2 millimetres (0.08 inch) in diameter. ... Conglomerates are usually subdivided according to the average size of their constituent materials into pebble (fine), cobble (medium), and boulder (coarse).
How are conglomerate rock formed?
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 lithification of gravel.
Where do you find conglomerate rocks?
Conglomerate rock occurs where gravel can become rounded by traveling distances or being subjected to tumbling. Beaches, riverbeds, and glaciers can produce conglomerate. The properties of conglomerate rock depend on its composition. It can be found in any color and may be either hard or soft.Jun 15, 2018
What is conglomerate stone?
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.
What rock type is a conglomerate rock?
sedimentary rock
What would conglomerate be used for and/or in what industrial process?
Properties and Uses When the matrix is soft, conglomerate may be crushed for use as a fill material in the construction and transportation industries. Hard conglomerate may be cut and polished to make dimension stone for interesting-looking walls and floors.Jun 15, 2018
What is the texture of conglomerate?
Type Sedimentary Rock
------------- ------------------------------------------------------------
Texture Clastic; Coarse-grained (2 – 64 mm)
Composition Quartz, Feldspar
Color Tan to brown
Miscellaneous Rounded clasts in a fine- to medium-grained matrix; Immature
Would a conglomerate be well sorted or poorly sorted?
In turbidites, the basal part of a bed is typically coarse-grained and sometimes conglomeratic. In this setting, conglomerates are normally very well sorted, well-rounded and often with a strong A-axis type imbrication of the clasts.
What is the rock cycle of conglomerate?
A Sedimentary Rock. Conglomerate is characterized by rounded pebbles cemented together. The pebbles can be most any kind of rock. ... After the pebbles have been deposited they are compacted by the sediments that pile up on top of them. Over very long periods of time the pebbles become cemented together by other minerals.
When was conglomerate formed?
How Does Conglomerate Form? Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. It takes a strong water current to transport and produce a rounded shape on particles this large. Wind transport is unlikely to produce a conglomerate.
