Gabbro | SpringerLink
Definition. Gabbro is a medium- to coarse-grained, mafic intrusive igneous rock, mostly grayish to greenish in color, and is the most abundant rock in the oceanic crust. Oceanic gabbros are mainly composed of three minerals: olivine, plagioclase, and clinopyroxene, sometimes associated with orthopyroxene, amphibole, and Fe-Ti oxides.

Basic hornfels at a gabbro contact near Carlingford, Eire
Thermal metamorphism of Silurian sediments at a gabbro contact took place under pyroxene-hornfels facies conditions. The most common hornfels is essentially composed of pyroxene and labradorite; its chemical composition compares with that of average gabbro. The hornfels is believed to have been metasomatically altered, probably basified, during ...
