Comment on 40Ar/39Ar age constraints on low-grade metamorphism and cleavage development in the Transvaal Supergroup (central Kaapvaal craton, South Africa): implications for the tectonic setting of the Bushveld Igneous Complex (South African Journal of Geology, 109, 393 410), by Alexandre et al. (2006)

South African Journal of Geology, 2007
Alexandre et al. (2006) recently presented the results of a detailed structural study of brittle-ductile deformation, which could, as they state, be seemingly coincident with regional low-grade metamorphism of the pre-2.15 Ga Transvaal Supergroup strata between the Vredefort impact structure of ~2.02 Ga age (Kamo et al. , 1996; Gibson et al.

The Geology of a Portion of the Santa Monica Mountains with a Section on Rock Cleavage

, 1931
A section of the Santa Monica Mountains lying in the eastern third of the Reseda Quadrangle and a portion of the western third of the Van Nuys Quadrangle comprises the geological mapping investigated by this report. The occurrence of a very thick section of pre-Jurassic metamorphic sediment interested the writer to make a study of the rock fracture ...
