2735	TR	Trachyte - A type of trachytic-rock. In the Rock Classification Scheme, this name is used for a fine-grained crystalline igneous rock when the modal mineralogy is available, and the mineral mode plots in field 7 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17a, 19.	R	Trachyte			GRBA	24-FEB-00	TMCM	22-FEB-19		Fine-grained, av. <0.25mm normal crystalline extrusive/intrusive rock; quartz <5% of QAPF, feldspar 65-90% alkali feldspar, TAS SiO2 57.6- 69wt%, Na2O+K2O >7wt%; normative quartz <20%	C
2736	TRAND	Trachyandesite - A type of trachytic-rock, classified using the total alkali silica (TAS) classification. The TAS classification may be used if the mineral mode of a normal fine-grained crystalline rock cannot be determined due either to the presence of glass or to the fine-grained nature of the rock. The definition of trachyandesite is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 20.	R	Trachyandesite			GRBA	24-FEB-00	TMCM	22-FEB-19		Fine-grained, av. <0.25mm normal crystalline extrusive/intrusive rock; TAS SiO2 53-63wt%, Na2O+K2O 5.9-11.7wt%	C

2739	TRBA	Trachybasalt - A type of trachytic-rock, classified using the total alkali silica (TAS) classification. The TAS classification may be used if the mineral mode of a normal fine-grained crystalline rock cannot be determined due either to the presence of glass or to the fine-grained nature of the rock. The definition of trachybasalt is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 20.
