526	DLSPT	Dolomite-sparstone - A type of dolostone, classified on the basis of its diagenetic texture. It is a dolostone composed of obliterative sparry crystals, with a crystal size larger than 32 µm. British Geological Survey Research Report RR/99/03, section 3.2, table 8 and fig. 7.	R	Dolomite-sparstone					GRBA	24-FEB-00	TMCM	08-MAR-19		Sedimentary rock with crystals >50% magnesium carbonate. Dolomite >50% of magnesium carbonate crystals. Petrological study shows obliterative sparry dolomite >0.032mm in inequant blocky mosaics. Crystal size not defined.	C
527	DLWST	Dolomite-wackestone - A type of dolostone, classified on the basis of its depositional texture. In the Rock Classification Scheme, it is a matrix-supported dolostone composed of less than 75% matrix (mud-grade material smaller than 32 µm).

529	DMTN	Diamicton - A type of siliciclastic sediment and sedimentary rock. Sediments that are poorly sorted and contain a wide range of clast sizes can be given this root name. The strict descriptive definition relates to range of particle size and not to relative abundance of any or all size classes. These sediment types therefore traverse the boundary of siliciclastic rudaceous, arenaceous and argillaceous sediments. This is the unconsolidated equivalent of diamictite. British Geological Survey Research Report RR/99/03, section 2 and figs. 2, 3 and 5.	R	Diamicton					GRBA	24-FEB-00	TMCM	08-MAR-19		Poorly-sorted sediment with wide clast size range, clasts >50vol% from pre-existing siliceous rocks. May be rudaceous, arenaceous or argillaceous grade.

538	DOLO	Dolostone - In the Rock Classification Scheme, sedimentary rocks which are composed dominantly of dolomite or ankerite are given this group name.
