APTICORE Cismon Well Data
The APTICORE program was designed to document the global oceanic anoxic events and understand the causal linkages among various geological processes that led to the mid-Cretaceous “greenhouse” climate state. The well drilled in 1996 in the Cismon Valley penetrated 131.8 m of limestones, marlstones and “black shales”, extending from the Upper Aptian down to the lower Upper Hauterivian (about 117-130 Ma) and can be considered a “reference section” for low latitudes. The hole was continuously cored and logged with a complete suite of logging tools (excerpt from
