IgRoCS is a computer program for igneous rock classification and is fully consistent with the International Union of Geological Sciences (IUGS). See in the paper published in Episodes. IgRoCS is an updated version of the well-known computer program SINCLAS (Verma et al., 2002, 2003).


Note that the IUGS scheme is only for fresh or relatively less altered igneous rocks.
