Editing Breccia (section)

===Sedimentary===
Sedimentary breccia is breccia formed by sedimentary processes. For example, [[scree]] deposited at the base of a cliff may become cemented to form a talus breccia without ever experiencing transport that might round the rock fragments.{{sfn|Jackson|1997|loc="sedimentary breccia", "talus breccia"}}
Thick sequences of sedimentary ([[colluvial]]) breccia are generally formed next to fault scarps in [[graben]]s.<ref name="LonghitanoEtal2015">{{cite journal |last1=Longhitano |first1=S.G. |last2=Sabato |first2=L. |last3=Tropeano |first3=M. |last4=Murru |first4=M. |last5=Carannante |first5=G. |last6=Simone |first6=L. |last7=Cilona |first7=A. |last8=Vigorito |first8=M. |title=Outcrop reservoir analogous and porosity changes in continental deposits from an extensional basin: The case study of the upper Oligocene Sardinia Graben System, Italy |journal=Marine and Petroleum Geology |date=November 2015 |volume=67 |pages=439–459 |doi=10.1016/j.marpetgeo.2015.05.022|bibcode=2015MarPG..67..439L |hdl=11586/139746 |hdl-access=free }}</ref><ref name="MasonEtal2017">{{cite journal |last1=Mason |first1=J. |last2=Schneiderwind |first2=S. |last3=Pallikarakis |first3=A. |last4=Wiatr |first4=T. |last5=Mechernich |first5=S. |last6=Papanikolaou |first6=I. |last7=Reicherter |first7=K. |title=A Multidisciplinary Investigation at the Lastros-Sfaka Graben, Crete |journal=Bulletin of the Geological Society of Greece |date=27 July 2017 |volume=50 |issue=1 |pages=85 |doi=10.12681/bgsg.11704|s2cid=134862302 |doi-access=free }}</ref>

Sedimentary breccia may be formed by submarine [[debris flow]]s. [[Turbidite]]s occur as fine-grained peripheral deposits to sedimentary breccia flows.<ref name="Moore1989">{{cite journal |last1=Moore |first1=P.

In a [[Karst topography|karst terrain]], a collapse breccia may form due to collapse of rock into a [[sinkhole]] or in [[cave]] development.<ref>{{cite book |last1=Demiralin |first1=A.S. |last2=Hurley |first2=N.F. |last3=Oesleby |first3=T.W. |title=Paleokarst Related Hydrocarbon Reservoirs |chapter=Karst Breccias in the Madison Limestone (Mississippian), Garland Field, Wyoming |year=1993 |pages=101–118 |publisher=Society for Sedimentary Geology |doi=10.2110/cor.93.18.0101 |isbn=1-56576-004-2 |url=https://archives.datapages.com/data/sepm_sp/CW18/Karst_Breccias_in_the_Madison.htm |access-date=2 April 2022}}</ref><ref name="Lopes2020">{{cite journal |last1=Lopes |first1=Tuane V. |last2=Rocha |first2=Aline C. |last3=Murad |first3=Marcio A. |last4=Garcia |first4=Eduardo L.
