The OCTek-Mediterranean study has investigated the rifted margins and offshore basins of the Mediterranean, Black Sea & Caspian Sea. It covers the region defined by 20° - 55°N, 20°W - 60°E and joins onto the existing OCTek-Atlantic & OCTek-Indian Ocean studies.
The OCTek-Mediterranean results will be of interest to those exploring or evaluating the offshore basins of:
• The whole of the Mediterranean Sea
• The Caspian Sea
• The Black Sea
• Offshore Morrocco & the Bay of Biscay
The primary output from OCTek-Mediterranean is a comprehensive suite of digital grids for the Mediterranean, Black Sea and Caspian Sea region which show :
1 Depth to Moho
2 Total crustal thickness
3 Residual continental-basement crustal thickness
4 Crust and lithosphere thinning/beta factor
5 The residual thermal gravity anomaly at the present-day
The results have been tuned to local breakup/rift ages within the basins and to local crustal reference thickness. They also explore a range of plausible scenarios for the amount of volcanic addition during rifting and breakup as well as a sensitivity to sediment thickness.
The suite of digital grids is available for unrestricted use by purchasing companies and institutions and is supported by an atlas of maps, which documents the techniques and data used together with a map-plot from all of the supplied grids.
OCTek-Mediterranean is based on analysis of data available in the public domain. OCTek gravity inversion is proven technology which has also delivered the OCTek-Atlantic, OCTek-Indian Ocean, OCTek-Asia/Pacific, OCTek-Arctic & N.Atlanic, OCTek-Australasia and OCTek-Gulf of Mexico studies together with confidential results on a proprietary basis from rifted margins worldwide.
A study applying the OCTek gravity inversion methodology to the conjugate South Australia – Antarctic margins has been made available for free public download by Geoscience Australia.
