Silicate Immiscibility in the Ancient “Basalts” of the Barberton Mountain Land, Transvaal

Nature Physical Science volume 235, pages 86–89 (1972)Cite this article

Abstract

The presence of spherical bodies in basaltic rocks strongly suggests that they are globules produced by liquid immiscibility of silicate fractions. Chemical analyses and experimental work support the concept that some of the rock types found in the Barberton Mountain Land, Transvaal, owe their origin to an unmixing of magmas.
