We interpret that these intervals contain megabreccias (chaotic facies) and sandy turbidites (parallel/laminated facies). One megabreccia is exposed on the sea floor displaying an overall fan shape having individual blocks measuring nearly 300 m across and >110 m high. The source area consists of a <i>scalloped</i> embayment with a headwall scarp 180 m high. Reflections within the platform are sharply truncated by this escarpment. This single megabreccia is ~120 m thick and extends ~27 km along slope and ~16 km out into the basin. Other megabreccias within the basin have individual blocks measuring >400 m across.Rocks from dredge hauls are a mixture of shallow- and deep-water facies. Shallow-water facies consist of mixed, skeletal grain-stones and <i>Halimeda</i> packstones. Deep-water facies are massive chalks, chalks with shallow-water skeletal grains, and chalk-block breccias. This indicates that the megabreccias formed as a result of bank-margin collapse, during which the ensuing debris flow eroded into slope and basin facies, mixing rock types together. We speculate that bank-margin-collapse events, resulting in megabreccia formation, may have been seismically triggered, and we emphasize that these large-scale, mass-wasting events occurred along margins of <i>low-relief</i> carbonate platforms.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Megabreccia shedding from modern, low-relief carbonate platforms, Nicaraguan Rise","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-09 01:31:29.547383","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1992,"MonPub":null,"DateUpdate":"2014-08-22","DateCreate":"2014-08-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1992JG43200002","VABBcode":null,"OpenAcc":0,"DOI":"10.1130/0016-7606(1992)104<0928:MSFMLR>2.3.CO;2"},"refs":null,"anarec":{"AnaID":240769,"PubliDate":1992,"Pagination":"928-943","XtraPublOfAnaID":null,"ISBN":null,"Volume":"104","Issue":"8","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42912,"SerRR":"Geological Society of America bulletin.
