888	LMPSST	Lime-pseudosparstone - A type of limestone, classified on the basis of its diagenetic texture. It is a limestone composed almost totally of a divergent radial fibrous calcite cement in which grains or in-situ biogenic material do not constitute a framework. The calcite pseudospar occurs as in-situ botryoidal masses commonly found in the core of algal mounds and probably formed from early diagenetic alteration of aragonite masses. The diagenetic process does not cause any alteration to the depositional or biological texture. British Geological Survey Research Report RR/99/03, section 3.1, table 3 and fig. 6.	R	Lime-pseudosparstone				GRBA	24-FEB-00	TMCM	08-MAR-19	Sedimentary rock, crystals >50% calcite/aragonite. Petrological study shows non-obliterative insitu botryoidal calcite pseudospar masses.

890	LMPT	Lamproite - A type of exotic crystalline igneous rock. There is no universally accepted definition for lamproites, however they occur characteristically as lavas, pipes and dykes. Some lamproites have a fragmental origin (i.e. they are volcaniclastic). In the Rock Classification Scheme they are classified on the predominance of phlogopite, richterite, olivine, diopside, sanidine and leucite. British Geological Survey Research Report RR/99/06, section 6.5.

891	LMPY	Lamprophyre - A type of exotic crystalline igneous rock. Lamprophyres are mesocratic to melanocratic igneous rocks, usually hypabyssal, with a panidiomorphic texture and abundant mafic phenocrysts of dark mica (biotite or Fe-phlogopite) and/or amphibole, with or without pyroxene, with or without olivine, and sometimes melilite, set in a matrix of the same minerals. Any feldspar, usually alkali feldspar, is restricted to the groundmass. British Geological Survey Research Report RR/99/06, section 6.7.

893	LMSD	Lime-sediment - In the Rock Classification Scheme, these are carbonate sediments in which the dominant carbonate mineral is calcium carbonate in the form of calcite, aragonite and/or vaterite (vaterite is a metastable hexagonal form of calcium carbonate. It is exceptionally rare and it is unlikely that it would ever occur as the main mineral). British Geological Survey Research Report RR/99/03, section 3 and fig. 6.

895	LMSND	Lime-sand - A type of lime-sediment. In the Rock Classification Scheme, it is a lime-sediment in which clasts are predominantly 32 µm to 2 mm, with less than 75% of the clasts smaller than 32 µm and less than 25% larger than 2 mm. The grain size classes are defined in the same way as the siliciclastic sediments. British Geological Survey Research Report RR/99/03, section 3.1, table 2 and fig. 6. See also: silicate-sand.	R	Lime-sand				GRBA	24-FEB-00	TMCM	08-MAR-19	Sediment with components >50% calcite/aragonite. Components >50% or predominantly sand-grade, 0.032 to 2mm.	C
896	LMSPT	Lime-sparstone - A type of limestone, classified on the basis of its diagenetic texture. It is a limestone composed of obliterative sparry calcite crystals, typically in inequant, blocky mosaics, with a crystal size larger than 32 µm. British Geological Survey Research Report RR/99/03, section 3.1, table 3 and fig. 6.	R	Lime-sparstone				GRBA	24-FEB-00	TMCM	08-MAR-19	Sedimentary rock with components >50% calcite/aragonite. Petrological study shows obliterative sparry calcite >0.032mm in inequant blocky mosaics. Component size not defined.	C
897	LMST	Limestone - In the Rock Classification Scheme, these are carbonate sedimentary rocks in which the dominant carbonate mineral is calcium carbonate in the form of calcite, aragonite and/or vaterite (vaterite is a metastable hexagonal form of calcium carbonate. It is exceptionally rare and it is unlikely that it would ever occur as the main mineral). Two classification schemes are available to give root names to limestones: the first scheme is based on texture; the second scheme is designed to classify limestones composed dominantly of one constituent. Textural classification includes use of depositional (i.e. matrix-supported versus grain-supported), biogenic, and diagenetic textures.
