I remember that (20 years ago!) in the suite of fortran codes for inverting plate kinematic data developped by Ted Chang, Jean-Yves Royer & Bessie Kirkwood one could distinguish between magnetic anomaly picks and fracture zone picks (fracture-zone crossings). Is this possible with GPlates or does GPlates only consider magnetic anomaly picks? Thanks.
