compaction and cementation
Conglomerate rocks are formed from rounded particles, while breccia rocks are formed from angular particles. This difference in particle shape is due to the transportation and deposition processes that these sediments undergo before forming rocks.
The conglomerate rock you're describing likely formed from the deposition of large, angular fragments that were transported by water or ice and then fused together during the lithification process. The angular nature of the fragments suggests that they were not significantly transported from their source, indicating a nearby origin for the rock.
Metaconglomerate gets its name from its composition and formation process. It is a type of metamorphic rock that originates from conglomerate, which consists of rounded clasts or gravel-sized particles. During metamorphism, the original conglomerate undergoes changes due to heat and pressure, resulting in the recrystallization of the clasts and the surrounding matrix, thus earning it the prefix "meta-" which means "change" in Greek. The term reflects its origin as a transformed version of conglomerate rock.
No because Conglomerate is made by sediments that are eroded by other rock or by dead plants and animals. The sediments are pushed or smooshed together by the pressuer sitting on top of it. This process is called compacton. This process turns the sediments into clasti sedimentry rocks. So Conglomerate is a clastic sedimantary rock.
The protolith of metaconglomerate is a sedimentary rock called conglomerate. Conglomerate is composed of rounded gravel-sized clasts that are cemented together. Through the process of metamorphism, this sedimentary rock undergoes changes in temperature and pressure to form metaconglomerate.
Conglomerate rocks are formed from rounded particles, while breccia rocks are formed from angular particles. This difference in particle shape is due to the transportation and deposition processes that these sediments undergo before forming rocks.
Lithification is the process by which loose sediment is transformed into solid rock through compaction and cementation. It involves the squeezing together of sediment grains and the binding of these grains by minerals dissolved in the groundwater, resulting in the formation of sedimentary rocks.
Compaction would likely be more significant as a lithification process for shale and sandstone due to their fine-grained composition, which is conducive to compaction. Conglomerate and breccia are coarser and have less room for compaction due to their larger grain sizes and irregular packing.
If the process of cementation is volcanic you get a "tuff". If the cementation post sedimentation of rock clasts you get a sedimentary rock which may be a breccia or a conglomerate.

A clump. Unless they have undergone compaction and cementation in a process known as lithification. Then they would be classified as a sedimentary rock, maybe conglomerate, breccia, or sandstone.
Pegmatite is a type of igneous rock that can have two different grain sizes of the same mineral present. This is due to the slow cooling process of the magma, allowing for the growth of large crystals (phenocrysts) within a finer-grained matrix.
The process is called 'lithification'. ----------------------------------------------------------- Another word you could use is 'diagenesis' which is any chemical, physical, or biological change undergone by a sediment after its initial deposition and during and after its lithification. ----------------------------------------------------------- The combined process of, accumulation, stratification, sedimentation, compaction, cementation, and lithification, of deposited materials and detritus to form sedimentary rocks is called diagenesis.
The process that could directly lead to the formation of pumice rock is volcanice eruptions (explosive eruption of lava from a volcano).
Breccia is a clastic sedimentary rock composed of various sized visible pieces of other rock, cemented together by the processes of lithification.The pieces of rock that are visible are angular fragments, meaning they have somewhat jagged edges. This means that the fragments in the breccia did not travel far before they were deposited. If they had traveled longer and further they would have become rounded, in which case the resulting sedimentary rock would have been called conglomerate.
