Cluster Meeting: Interpretation of Tectonics of Passive Margin of NE Greenland

Date: Thursday, 4th October 2012

Venue: Royal Cambrian Academy in Crown Lane, Conwy @ 6:30.  Refreshments @ 6:00.

Speaker Biography:

Dr Menno G. Dinkelman joined ION-GX Technology in 2005. He is Chief Geologist BasinSPAN Programs with primary focus on the interpretation of the Arctic, North Atlantic and SE Asia programs. Prior to joining ION-GXT Dr Dinkelman was principal geologist at Gaffney, Cline & Associates. Throughout the 1980’s he was a senior research scientist /geologist Conoco and ARCO, and exploration advisor for the Ministry of Oil and Mineral Resources in the Yemen Arabic Republic.  From 1973 to 1980 he was on the faculty of the Department of Geology at Florida State University. He has intermittently worked as an independent consulting geologist in Europe and the US. Dr Dinkelman holds degrees in the Natural Sciences and Geology from the ETH in Zürich and a PhD in Geological Oceanography from Oregon State University.  He is a member of HGS, GCAGS, SEPM and SEG.

 

Abstract:

Three phases of deep 2D seismic acquisition and PSDM processing over the past 4 years provide regional coverage of the NE Greenland Atlantic passive margin.  It is a Tertiary volcanic-rich passive margin developed upon a Caledonian orogenic crust and its cover. A foundation of Late Paleozoic successor basins, Mesozoic extensional basins, and earliest Tertiary transpressional zones are characterized by complexity now inherited in the segmentation and geometry of the passive margin prism. The array of basins and their deep architecture suggests a west to east, chronological progression of pre-rift, sag and oceanic rift basins in the NE Greenland shelf and slope. This presentation reviews the geology of the NE Greenland margins, one of the few remaining, completely undrilled major petroleum basins, incorporating the knowledge from recent seismic imaging.
