This northwestwards widening splay of Late Carboniferous – Early Permian fault zones in the Danish region emanates from the Teisseyre-Tornquist Zone in northern Poland. Seismic reflections and velocity anomalies image collisional fault zones that formed during the Proterozoic and Palaeozoic amalgamation of the crust. Re-equilibration of Moho appears to have taken place before late Palaeozoic rifting and magmatism initiated the main phase of basin formation that continued into the Mesozoic. The resulting, strong Moho topography, with variation between depths of 26 and 48 km, has been practically “frozen in” since then, although the late Cretaceous – early Cenozoic inversion tectonics may have formed a crustal keel underneath part of the Sorgenfrei-Tornquist Zone which cuts across the Proterozoic crust of the Tornquist Fan region.","PeriodicalId":55310,"journal":{"name":"Bulletin of the Geological Society of Denmark","volume":"46 1","pages":"145-160"},"PeriodicalIF":1.2,"publicationDate":"1999-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69889173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of bioerosion on the calcification/dissolution budget of reefal waters and on particulate calcium car-bonate fluxes was investigated. Studies on bioerosion were performed in order to assess: (a) eroding activity of grazers through the gut content analysis of echinoids and scarid parrot fish, (b) eroding activity of micro- and macroborers from ex-perimental substrates exposed for one year, and (c) role of sponges in total bioero-sion on reefal and experimental substrates.
