Title A name given to the resource Igneous Rocks Subject The topic of the resource This collection covers both volcanic and intrusive rocks, including rhyolites, granites, diorites, andesites, basalts, gabbros, diabases, pumices, obsidians, syenites, phonolites, peridotites, carbonatites, dacites, trachyte, dunites, xenoliths, ignimbrites, and pegmatites. Creator An entity primarily responsible for making the resource Bereket Haileab Source A related resource from which the described resource is derived Housed in Anderson Hall, Carleton College. Format The file format, physical medium, or dimensions of the resource Thin sections, thin section scans, hand samples, hand sample images, photomicrographs, chemical analyses (major elements, trace elements and REE analyses for selected samples). Thin section and hand sample Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections. For more information see, http://dublincore.org/documents/dces/. Title A name given to the resource BH250-206b Subject The topic of the resource Ijolite Description An account of the resource Major Minerals: augite (clinopyroxene), titanoaugite (clinopyroxene), hypersthine (orthopyroxene), plagioclase Minor Mineral: biotite, sphene (titanite), oxides Optical Features and Texture: Hypersthene exhibits faint pleochroism, while clinopyroxene display anomalous interference colors. The rock shows a characteristic subophitic texture, in which larger plagioclase crystals partially to completely enclose smaller pyroxene grains.
