According to the classification petrogenesis

Shore conglomerate : mainly formed in the coastal region and the Lake area , which is carried by the river into the gravel or rock avalanches along the coast by waves and debris down the river repeatedly adapted from. Fluvial conglomerates : Conglomerate mountain rivers and plains of the river called the river into a conglomerate formed , composed of multi- lithic conglomerate . grinding mills for sale The average particle size than the marine gravel gravel large, but poorly sorted gravel . Moraine conglomerate : gravel with silt and mud debris level mainly gravel grade detrital content – like accounting for 5-30 % , poor sorting , particle sizes. Moraine rock identification features are: gravel oddly shaped, forming the so-called Iron pentagonal shaped gravel or gravel , T-shaped surface scratches . Karst breccia ( collapse breccia , cave breccias ) : formed by dissolution of carbonate cave , cave formed by a top wall caving lime , dolomitic breccia accumulation, which in turn is caused by cemented calcareous or clay . Identification characteristics: size difference brecciated hanging beads, clear edges and corners , mostly limestone, dolomite fragments . Fillings carbonate fines , red clay, the pores often crystalline calcite . Karst breccia often lead-zinc enrichment of place , is to find rich lead and zinc , antimony ore prospecting signs.

Volcanic breccia : are pyroclastic material ( cuttings , pulp chips, accounting for more than 30% of the total rock volume ) was formed by a small rock debris ( ash , glass crumbs ) cemented between 0.02-6.4cm . Much higher than those contained in the tuff lava debris was more, but glassy and crystalline flakes crumbs less . Some volcanic breccia how the amount of volcanic slag, gravel multi- block with angular diameter of about 10-30cm in the majority, no significant accumulation of bedding, poor sorting , chosen by volcanic material cement , cement rock that ‘s part of the close , gravel block no obvious boundaries between cements . Volcanic breccia can be distributed on the volcano not far from the crater slopes, the eruption cycle time is often formed in the beginning stages , set after the rock heap . Volcanic breccia bodies and are looking for volcanic volcano-tectonic control of ore deposits sign , because its own good permeability, often for the ore- rock .Cement Clinker Grinding Plant

Fault breccia or tectonic breccia : refers to the stress ( faulting ), the original broken into brecciated rock was crushed fines partially filled with cement or foreign substances cemented rock. Generally considered: brecciated debris content greater than 30% is called the fault breccia , and debris content of less than 30% are called fault gouge . It is the driving force in the fragmentation of moderate metamorphic rocks . Tectonic breccia in fault fracture zone is widely distributed . Its thickness depends on the crushing strength. Sometimes several hundred meters thick , extending tens to hundreds of kilometers . Identification of fault breccia features : 1 ) on both sides of the fault breccia composed of rock , cement powder to rock , fault gouge and hydrothermal substances, such as siliceous , iron, calcium , etc. ; 2 ) has a dynamic metamorphism phenomenon as tectonic lenses , extruded sheet management, fault folds ; 3 ) was linear, consistent with the fracture distribution ; 4 ) fault breccia often associated with fault gouge gouge conglomerate, Loose rocks , broken porphyry, cracked rocks form a complete sequence of zoning ; 5 ) is looking for signs of hydrothermal deposits. grinding mills for sale

Hydrothermal breccia ( hydrothermal breccia ore fluid fracturing breccias ) : If hydrothermal overburden pressure is greater than the static pressure of the volatile parts of catastrophic escape , the rapid expansion of the volume , so that the occurrence of hydrothermal rock blasting and the formation of breccia , called hydrothermal breccia ( hydrothermal breccia ore fluid fracturing breccias ) . Hydrothermal breccia blasting identification characteristics: 1 ) often have a round, oval or broadband -like morphology ( ie blasting breccia pipe ) , and fault breccia different linear form ; 2 ) blasting around hydrothermal centers, was blasting rock powder distribution ring with belt, blasting breccia, shattered rock, shattered rock ; 3 ) blasting is often brecciated breccia rock material , cements hydrothermal material with hydrothermal breccias edge alteration side ( fade side ) , can be put together with a characteristic breccia ; 4 ) outwards , hydrothermal alteration gradually weakened by the blast center , the eventual transition to perforation alteration spot ; 5 ) is looking for gold, silver , copper so good prospecting mark .
