1. Applied Geodynamics Physical Modeling Lab
This lab studies salt tectonic processes using scaled physical models run under a variety of driving forces, including gravity and differential loading, extension, contraction, and strike-slip. Founded in 1989, this is one of the only laboratories in the world whose sole purpose is the study of salt tectonic processes.
Existing Equipment: Three multifunction deformation rigs can accommodate models up to 2 m long and 1.5 m wide. Models are recorded using standard high-resolution digital cameras (Canon Rebel T1i and T2i). In addition, the upper surfaces of the models are recorded using LaVision Strainmaster stereo digital image correlation system (x2), allowing us to track motions and surface strains in 3D. Additional surface monitoring is done by a Basis Surphaser laser scanner.
