Terrane correlation between Antarctica, Mozambique and Sri Lanka: Comparisons of geochronology, lithology, structure and metamorphism
Summary Analysis of lithological, structural, metamorphic and geochronological data from mapping in Mozambique permits recognition of two crustal blocks separated by the Lurio Belt. Comparison of the data, with data from Sri Lanka and Dronning Maud Land (DML) permits recognition of similar blocks in...
