Work commenced June 2014 (Phase 1) and will continue according to the broad plan described below. Note that quite often research can produce interesting results that were not originally conceived. For example, results might indicate that additional field trips are needed. Therefore, the plan may be modified with appropriate notification of consortium members.
Phase 1
- Carry out a literature study to define focus areas of study, including comparisons with other rifted margins where similar igneous activity and vertical movements have been reported.
- Initiate construction of an interactive database of existing geophysical, geological, geochemical and stratigraphic information to target critical study areas and prepare for field work and analyses.
- Geophysical and geological data modeling (reflection and refraction seismic, earthquake receiver functions, potential fields, geodynamic, geochemical etc.) to examine stratigraphic relationships as well as sedimentary and crustal structures.
Phase 2
- Field trip to collect field data (geochemistry, stratigraphy), samples and analyses.
- Continued geophysical and geological data modeling.
- Geochemical analysis of samples collected to determine their thermal history, composition, mantle sources and age.
- Generate project-specific geologic maps and horizons specifically related to the regional and local structures and igneous bodies.
- Begin developing potential model setups for Geodynamic modeling.
Phase 3
- Update igneous database with new samples and analyses.
- Continued geophysical and geological data modeling.
- Continued geologic mapping related to the regional structures and igneous activity.
- Identify sets of geodynamic models that best explain the basement structure, magmatic history of the margin.
