Abstract
The low δ18O value of some calcite cements (â11.62â°, â12.66â°, â14.31â° PDB) suggests that an influx of meteoric water may have occurred in the Turonian-Coniacian, although the low value could also result from an abnormal geothermal gradient associated with tectonic activity in the trough. The elemental and isotopic composition of these cements varies as a function of the time of precipitation.
