Investigation of diagenesis in sediment core CRP-1 from the Ross Sea, Antarctica, supplement to: Baker, Julian C; Fielding, Christopher R (1998): Diagenesis of glacimarine Miocene strata in CRP-1, Antarctica. Terra Antartica, 5(3), 647-653

Julian C Baker & Christopher R Fielding
A diagenetic study was carried out on the cored Miocene section in CRP-1 by thin-section, X-ray diffraction, scanning electron microscope, electron microprobe and stable isotopic analysis. Carbonate (calcite, siderite) microconcretions occur locally within intergranular pores and open fractures, and some sands are cemented by microcrystalline calcite. Calcite cement at 115.12 mbsf (metres below sea floor) and possibly microconcretionary calcite at 44.62 mbsf record infiltration of meteoric waters into the section, consistent with sequence stratigraphic evidence...
