X-ray diffraction analyses data indicate varying carbonate compositions. Pure calcites are rare but were found at Sites 1246 and 1252. Low- and high-magnesium calcites are the dominant carbonate mineralogies and occur at all sites. The presence of dolomite is characteristic for the slope basin sites. The sampling depth of the carbonates varies from near seafloor to deep within the accretionary complex, suggesting different modes of carbonate formation. The summit, flank, and slope basin sites show characteristic carbonate compositions with different carbonate contents in distinct depth intervals.completedOceanographyMineralogy of non-silicatesaccretionary wedgesauthigenic mineralscarbonatesCascadia subduction zonedolomiteEast PacificgeochemistryHydrate RidgeLeg 204marine sedimentsNorth PacificNortheast PacificOcean Drilling Programocean floorsPacific OceansedimentsX-ray diffraction dataurn:org.iodp:exp:204urnlargerWorkCitationcampaignEnglishgeoscientificInformation-125.0900-125.040044.340044.3500Data report; available only on CD-ROM in PDF format and on the Web in PDF or HTMLapplication/pdfunknownSEDIS Publication Catalogue
