Carbon and oxygen isotopic survey of diagenetic carbonate deposits in the Agardhfjellet Formation (Upper Jurassic), Spitsbergen: preliminary results
ABSTRACT: Diagenetic carbonate deposits (concretions, cementation bodies and cement− stone bands) commonly occur in organic carbon−rich sequence of the Agardhfjellet Forma− tion (Upper Jurassic) in Spitsbergen. They are dominated by dolomite/ankerite and siderite. These deposits originated as a resu...
