Add a definition The third stage includes the emplacement of severaldaciticdomes outside of the central crater and at different times. From theCambridge English Corpus This is consistent with the major-element data and a primarily andesitic source, modified bydaciticand more felsic components. From theCambridge English Corpus C9 member is a 500 m thick sequence of moderately dipping (20°), massive, highly welded crystal-richdaciticignimbrites. From theCambridge English Corpus An alternative view holds that a very large crystalrichdaciticchamber may be the product of protracted growth of a shallow magma system that was never near its liquidus. From theCambridge English Corpus Due to the compression of the magma chamber, basaltic lava rose from the bottom to the higherdaciticmagma chamber at 8 km deep.

Thesedaciticmagmas may have evolved by the accumulation of multiple injections of mushy magma sustained over hundreds of thousands of years. From theCambridge English Corpus It must be noted that this algorithm is mainly calibrated for basaltic todaciticmelts and that it is less accurate for granitic liquids. From theCambridge English Corpus The majority of these are rhyolitic/dacitic/trondhjemitic and basaltic, commonly hosting massive sulphide deposits of economic importance. From theCambridge English Corpus The eruptions started with production of rhyolitic magma followed bydaciticto basaltic andesite magma. From theCambridge English Corpus Shortly before eruption, adaciticmagma has evolved into a water-rich melt laden with 40 to 50 % crystals. From theCambridge English Corpus The evolution of adaciticmagma system over an approximately 1 million year time period is shown in this series of cross-sections. From theCambridge English Corpus In contrast, monotonousdaciticmagmas may never have been crystal-free near-liquidus magmas. From theCambridge English Corpus The roof collapses (e) and triggers eruption of the crystal-richdaciticmagma. From theCambridge English Corpus Furthermore, the eruptive characteristics and inferred crystallization histories imply that this type of crystal-richdaciticmagma was never near its liquidus. From theCambridge English Corpus It consists of weldeddaciticignimbrites, which lack quartz crystals and are further distinguished by zoned plagioclase crystal fragments. From theCambridge English Corpus In contrast, most comparable deposits described from the geological record are typicallydacitic-rhyodacitic and contain rhyolitic glass. From theCambridge English Corpus Daciticto andesitic basalts contain phenocrysts of pyroxene, altered feldspar and minor quartz often set in a groundmass of epidote-chlorite-glass. From theCambridge English Corpus Eruption from such a chamber produces a deposit that isdaciticand somewhat variable in composition, but not systematically zoned. From theCambridge English Corpus Several very large volume (> 1000 km of erupted magma) ignimbrites aredaciticand lack the vertical zonation found in many other tuffs.
