In accretionary margins, the estimation of peak heating through the thermal maturity of organic material reveals differentiated deformational pathways in the adjoining sections of the wedge. As the thermal maturity of the deformed structures is a function of both the geothermal gradient and the duration of time it has been exposed to different gradients, the distribution of vitrinite reflectance (the measure of thermal maturity) in the wedge does not necessarily reveal the temporal deformational pathway of the individual pockets. As a result, the different portions of the accretionary wedge exhibit different correlations between the thermal maturity and a unique deformational pathway. These different correlations can be explored through the means of geodynamic modelling which can then be used in the field to ascertain a more holistic picture of deformation in an accretionary wedge. Therefore, in this study, we use a 2D plate subduction thermomechanical model, to simulate formation o...
