Summary

This chapter focuses on how the thermal evolution of transform margins is controlled by deformation related to ridge migration parallel to the margin, creating pronounced thermal perturbation. It draws from insights provided from the three-dimensional thermal finite element models using a kinematic boundary condition to account for sea-floor spreading center migration. The models are used to quantitatively investigate the complex spatial patterns and temporal changes in the thermal regime of the ocean–continent transform development stage and subsequent transform margin. The models demonstrate the consequences for the uplift history, structural style and crustal structure of a transform margin as lithospheric strength is strongly temperature dependent.
