Title A name given to the resource Metamorphic Rocks Subject The topic of the resource This collection includes slates, phyllites, schists, gneisses, eclogites, marbles, quartzites, skarns, granulites, and mylonites. 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 BH250-48 Subject The topic of the resource Gneiss Description An account of the resource Major Mineral: Allanite Other Major Minerals: Microcline, orthoclase, biotite, quartz, perthite Mineralogical Comments: Very large allanite crystals are present and show significant alteration. Myrmekite is common in association with feldspars. Alteration: Allanite is extensively altered, displaying patchy zoning, partial replacement rims, and loss of interference colors. Signs of metamictization and radiation damage are evident, including pleochroic halos around radioactive inclusions.
