The submarine morphology is related clearly to the tectonic setting. Complex transform faulting has ruptured the crust seaward of the Honduras continental margin into a series of deep grabens separated by irregular submarine ridges. Because of the proximity of the Cayman Trough, the western continental margin is a faulted platform characterized by an irregular shelf as narrow as 10 km and a steeply dipping slope; both shelf and slope have been modified substantially by the growth of thick reef masses. Further east, tectonism is reduced as a result of the divergent trends of the Cayman Trough and the Honduras continental margin. Consequently, the eastern margin sector is a depositional platform consisting mostly of a broad, smooth shelf and gentle slopes. Submarine erosion and local slumping have steepened the slope throughout the area.</p></div>","PeriodicalId":11253,"journal":{"name":"Deep Sea Research and Oceanographic Abstracts","volume":"23 9","pages":"Pages 839-847"},"PeriodicalIF":0.0,"publicationDate":"1976-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0011-7471(76)90851-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90862705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
