Title	rhyolitoid (en)
described by	http://www.foodie-cloud.org/about/id/entity/https/inspire.ec.europa.eu/codelist/LithologyValue/LithologyValue.en.rdf
Description	fine_grained_igneous_rock consisting of quartz and alkali feldspar, with minor plagioclase and biotite, in a microcrystalline, cryptocrystalline or glassy groundmass. Flow texture is common. Includes rocks defined modally in QAPF fields 2 and 3 or chemically in TAS Field R as rhyolite. QAPF normative definition is based on modal mineralogy thus: less than 90 percent mafic minerals, between 20 and 60 percent quartz in the QAPF fraction, and ratio of plagioclse to total feldspar is less than 0.65.
