The mineralogy at both locations is qualitatively very similar, with quartz and phyllosilicates dominating the assemblages and calcite, dolomite, K-feldspars, plagioclases, and halite present in varying amounts. Ankerite (iron-rich dolomite) was observed in only one sample. Although the composition of the sediment is relatively monotonous, trends in the percent occurrence of each fraction are observed and can be linked to changes in the lithostratigraphic units and core descriptions from Expedition 308. The data presented here will help establish a link between geomechanical behaviors of the sediments and matrix effects driven by mineral composition.completedGeochemistry of rocks, soils, and sedimentsOceanographyankeriteAtlantic OceanboreholesBrazos-Trinity BasincalcitecarbonateschloridescoresdolomiteExpedition 308feldspar groupframework silicatesGulf of MexicohalideshaliteIntegrated Ocean Drilling ProgramIODP Site 1320IODP Site 1324marine sedimentsmineral assemblagesmineral compositionNorth Atlanticnorthern Gulf Of Mexicoquartzsedimentssheet silicatessilica mineralssilicatesUrsa BasinvariationsX-ray diffraction dataurn:org.iodp:exp:308urnlargerWorkCitationcampaignurn:org.iodp:exp:308:site:U1320urnlargerWorkCitationstudyurn:org.iodp:exp:308urnlargerWorkCitationcampaignurn:org.iodp:exp:308:site:U1324urnlargerWorkCitationstudyurn:org.iodp:exp:308urnlargerWorkCitationcampaignEnglishgeoscientificInformation-94.2300-89.080027.180028.0500application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://publications.iodp.org/proceedings/308/ERR/CHAPTERS/308_214.PDFdownload
