Divergent boundary: In the oceanic crust, basalt forms near the surface at a divergent boundary, but gabbro forms at depth from slow crystallization. Basalts 8. Pillow Lava 11. GABBRO, in petrology, a group of plutonic basic rocks, holocrystalline and usually rather coarse-grained, consisting essentially of a basic plagioclase felspar and one or more ferromagnesian minerals (such as augite, hornblende, hypersthene and olivine). Granite 2. This has important implications for some current petrological and chemical models of the moon. All Igneous Rocks have similar properties and formation process. The poor development of cryptic layering and the absence of ferro gabbro at Duluth, in contrast to their remarkable development in the Skaergaard Intrusion, can be explained by differing tectonic stability. Granodiorite 25. Geological maps and sections help considerably in planning many engineering projects. Gabbro comes under Igneous Rocks. Also, the metals and minerals found in rock play an important role in our life. Pegmatites 9. The rock gabbro shows the following textures: Cumulus:- Here they are formed by the accumulation of crystals that settled out from a magma by the action of gravity they are in liquid form.It shows euhedral grain size. Gabbro is a mafic plutonic rock with mineralogy and chemistry that spans the range between granitic rocks, which are silicic rather than mafic, and ultramafic rocks. What is Basalt.

This study aimed to determine the differences in morphological, physical, and chemical properties of the soils developing from gabbro, phylitte and chert parent rock. The rock series is similar in many respects to that of the Skaergaard Intrusion, but there are important differences that can be explained by dissimilar tectonic history. Gabbro has more basic cations, especially Ca and Mg, than granitic rocks, and commonly less Al (except gabbro with much hornblende or feldspar); consequently, the cation-exchange complexes of gabbro soils generally have larger percentages of basic cations (greater base saturation) than the cation-exchange complexes of granitic soils.
