| 150 | B | Boulders [Unlithified Deposits Coding Scheme] - A type of natural superficial deposit. The Unlithified Deposits Coding Scheme was developed as a way of coding unlithified deposits (also commonly referred to as superficial deposits, unconsolidated deposits, or engineering soils) that is consistent with civil engineering industry usage (BS5930). | R | Boulders [UDCS] | AWEL | 09-JAN-02 | TMCM | 13-MAR-19 | Not Available | C | |||||
| 151 | BA | Basalt - A type of basaltic-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 fields 9 and 10 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. Andesite and basalt may be separated chemically using SiO2 content: if wt% SiO2 is less than 52% the rock is basalt. British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17a, 19. | R | Basalt | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | Fine-grained, av. <0.25mm normal crystalline extrusive/intrusive rock; CI >35 vol% >40 wt%; quartz <20% or feldspathoid <10% of QAPF, feldspar >65% plagioclase; TAS SiO2 45-52wt%, Na2O+K2O <5wt% | C | |||||
| 152 | BAALK | Basalt, alkali - A type of basalt (TAS). In the Rock Classification Scheme, the root name basalt (TAS) may be divided into alkali basalt and subalkali basalt according to the state of silica saturation. If the analysis contains normative nepheline the rock may be called an alkali basalt. British Geological Survey Research Report RR/99/06, section 5.2. | U | Alkali basalt | alkali | AWEL | 22-JUL-02 | TMCM | 22-FEB-19 | Fine-grained, av. <0.25mm normal crystalline extrusive/intrusive rock; CI >35 vol% >40 wt%; quartz <20% or feldspathoid <10% of QAPF, feldspar >65% plagioclase; TAS SiO2 45-52wt%, (97% have <48.5), Na2O+K2O 1.4-5wt%, (97%>2.2). CIPW norm with nepheline. | C | ||||
| 153 | BAANDT | Basaltic-andesite - A type of andesitic-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 basaltic-andesite is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 20. | R | Basaltic-andesite | GRBA | 05-MAY-00 | TMCM | 22-FEB-19 | Fine-grained, av. <0.25mm normal crystalline extrusive/intrusive rock: TAS SiO2 52-57wt%, Na2O+K2O <5.9wt% | C | |||||
