These are coarsegrained plutonic rocks of basic character. Plagioclase felspars of limesoda composition ( labradorite and anorthite) are the chief constituents of gabbros. Besides these, the mafic minerals like augite, hornblende, olivine, biotite and iron oxides are also common as accessory minerals. Texture:

Abstract: The supremacy of the mineral industry added to the necessity to supply the world market demand justifies the continuous research efforts for optimizing of the activities of mineral resource utilization. In an approach of mineral characterization, a grainsize analysis study of coarse and fine aggregates of verdete rock was presented in this work.
· Classifiion of Igneous Rocks. Igneous rocks are CLASSIFIED according to their mineral composition and texture.. Minerals form as molten rock crystallizes. A generalized order of crystallization of minerals is shown in the Bowen's Reaction the magma cools, first olivine, then pyroxene, then amphobole, etc. will be crystallized (assuming the proper .

Name a fine grain, vesicular igneous rock which contains Plagioclase feldspar, Biotite, and Olivine. The only rocks that have fine grain AND are vesicular are Vesicular Rhyolite, Vesicular Andesite, and Scoria/Vesicular Basalt. Now we have to look to the mineral content to narrow the possibilities. The key is the Olivine which is found in only ...
