2100	MYLO	Mylonite - A type of mylonitic-rock. In the Rock Classification Scheme, it is one in which porphyroclasts comprise 10 - 50% by volume of the rock. British Geological Survey Research Report RR/99/02, section 7.3 and table 5.	R	Mylonite			GRBA	24-FEB-00	TMCM	22-FEB-19		Deformed (ductile), intensely foliated rock (protolith undefined) with primary cohesion, containing 10-50% porphyroclasts(commonly lensoid with tails indicating shearing sense) in a finer grained dynamically recrystallised matrix	C

2102	MYLTIC	Mylonitic-rock - A type of foliated mechanically broken rock with primary cohesion. Mylonitic rocks represent the products of dominantly ductile deformation. They generally occur within restricted zones related to faults, thrusts or shear zones. These foliated rocks develop as a result of grain size reduction by a combination of breakage and plastic strain of grains. Plastic deformation increases the aspect ratio of affected minerals producing textures such as quartz ribbons and a foliated fine-grained matrix. Other minerals, for example feldspar and garnet, may resist ductile deformation or fracture in a brittle manner and remain significantly larger than the foliated matrix. These are commonly lens shaped and termed porphyroclasts. As mylonitisation proceeds, the porphyroclasts are progressively wrapped by and then become isolated within the foliated matrix. They also become smaller, either by fracturing or by marginal erosion. Porphyroclasts may develop asymmetrical tails which can indicate the sense of shearing (dextral or sinistral) within the mylonitic rocks. Mylonitic rocks are classified into protomylonite, mylonite, and ultramylonite based on the percentage of visible porphyroclasts within the streaky, platy, fine-grained matrix.

2103	MZ	Monzonite - A type of syenitic-rock. In the Rock Classification Scheme, it is a coarse-grained crystalline igneous rock whose mineral mode plots in field 8 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. British Geological Survey Research Report RR/99/06, section 5.1 and figs. 9, 11, 12.	R	Monzonite			GRBA	24-FEB-00	TMCM	22-FEB-19		Coarse-grained, av. between 2-16mm normal crystalline intrusive rock; quartz <5% of QAPF, feldspar 35-65% plagioclase, +/- mica/amphibole	C

2105	MZDI	Monzodiorite - A type of dioritic-rock. In the Rock Classification Scheme, it is a coarse-grained crystalline igneous rock whose mineral mode plots in field 9 of the quartz - alkali feldspar - plagioclase - feldspathoid (QAPF) diagram. Monzodiorite and monzogabbro are separated according to the average composition of their plagioclase: if An (the anorthite content of plagioclase) is less than 50% the rock is monzodiorite. British Geological Survey Research Report RR/99/06, section 5.1 and figs. 9, 11, 12.	R	Monzodiorite			GRBA	24-FEB-00	TMCM	22-FEB-19		Coarse-grained, av. between 2-16mm normal crystalline intrusive rock; quartz <5% of QAPF, feldspar 65-90% plagioclase (<50% An), +/- mica/pyroxene/amphibole/olivine	C
