	Research in Structural Geology & Tectonics
	As well as extensive R&D involving digital mapping, laser-scanning and virtual outcrop models, we also committed to core research in structural geology and tectonics, with a focus on the complexities of oblique extension and collision (i.e. transtension and transpression).
	See here for recent publications and conference presentations related to digital geological mapping and construction and interpretation of virtual outcrop models.
