From theCambridge English Corpus As noted, the naturaldaciteignimbrites are phenocryst-rich. From theCambridge English Corpus For pressures < 0.5 kbar, the bulk density of the replenishing magma is typically lower than that of the hostdaciteon injection. From theCambridge English Corpus The viscosity of the waterpoor but silica-rich rhyolite magma is about 0.5 log units higher than for the water-richdacitemagma at a given temperature. From theCambridge English Corpus These important rheological transitions occur near the crystallinity of the very large volume dacites considered here. From theCambridge English Corpus For systems lying above the line, the replenishing magma will become less dense than thedacitewhile it is still hotter than the resident magma. From theCambridge English Corpus The calculations were carried out at 1 kbar, using an average enclave composition and an averagedacitecomposition from the 1940 flow.
