"Influence of Volcanism and Associated Magmatic Processes on Petroleum Systems"
Abstract Submission Deadline: 1 July 2016
Review the abstract submission instructions before submitting abstracts to .
The field trip is organized privately by the technical committee and is a non-AAPG activity. AAPG assists with marketing of the field trip. Registration for the field trip is open only to GTW Delegates and should be made when registering for the GTW. Registration fee (when available) will encompass the field trip component; there will be no “workshop-only” fee should a delegate not attend the field trip.
The field trip will visit local outcrops of basaltic pillow lavas, seamounts, and feeder dykes and sills into an Oligocene carbonate shelf. Features similar to those seen in outcrop can be observed in seismic sections and exploration wells offshore in the late Cretaceous and Tertiary Canterbury basin and so are representative of the effects of volcanism on the petroleum system. The pyroclastic deposits around the seamounts may function either as reservoirs or as seals and their emplacement clearly affected the distribution of carbonate reservoir facies around the seamounts on and around the volcanic platform. Local intrusions interact with carbonate minerals and seawater producing local to regional diagenetic changes possibly also affecting maturation. Delegates will be taken to outcrop localities that will show all of these features.
More details will be made available in due course.
