Introduction
The increased availability of high-quality seismic and potential field data has shown that extensional processes can lead to complex crustal configurations, depending on lithospheric composition, thermal structure and heat transfer, far-field stresses, extension rate and duration, mantle flow, and structural inheritance.
This study aims to understand the factors controlling margin structure by analyzing the evolution of the central west Greenland margin. This area is located northeast of the Ungava transform zone and sits at the junction of two Precambrian orogenic belts that affect the basement (Figure 1).
The large mantle melting during the Paleogene and the subsequent development of a volcanic passive margin make the margin's structural and thermal evolution complex.
Aim of the study
- Understand the early sedimentary evolution and kinematic history of the area
- Improve constraints on the transition from the sedimentary basin to the volcanic passive margin
- Investigate the effects of the Ungava transform system and structural inheritance on the margin structure
Data and Methods
This study will incorporate seismic data interpretation combined with previous field observations. Additionally, we will utilize magnetic and gravimetric data to enhance our understanding through an integrated seismic-gravity and magnetic interpretation approach.
