DOI: 10.17491/jgsi/2024/174011
Abstract: The Kadavur anorthosite-gabbro complex (10°35′N: 78°11″E), Tamil Nadu, consists of the three distinct rock units which are layered anorthosite-gabbro, schistose anorthosite-gabbro, and sporadic pegmatoidal variant. Based on texture, the layered-type can again be divided into… read more here.
