256 BSN  Basanite - A type of tephritic-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 14 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. Basanite and tephrite are distinguished by the amount of olivine in the CIPW norm: if normative olivine exceeds 10% the rock is basanite.

259 BSNFDI  Basanitic-foidite - A type of foiditic-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 15b of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. Basanitic-foidite and tephritic-foidite are distinguished by the amount of olivine in the CIPW norm: if normative olivine exceeds 10% the rock is basanitic-foidite. British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17a, 19.  R  Basanitic-foidite          GRBA  24-FEB-00  TMCM  22-FEB-19    Fine-grained, av.<0.25mm normal crystalline extrusive/intrusive rock; feldspathoids 60-90% of QAPF, feldspar >50% plagioclase, olivine >10%+B35  C 
260 BSNT  Basanite (TAS) - A type of tephritic-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 basanite (TAS) is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 20.  R  Basanite (TAS)          GRBA  24-FEB-00  TMCM  22-FEB-19    Fine-grained, av.<0.25mm normal crystalline extrusive/intrusive rock; olivine >10%; TAS SiO2 41-49.4wt%, Na2O+K2O 3-9.4wt%  C
