292	CANL	Cannel-coal - A type of sapropelic-coal. It is a dull black, has a waxy lustre, is homogeneous, has concoidal fracture, and is rich in miospores with very little alginite. Macroscopic examination shows no stratification. Microscopic examination shows that compared with humic coals the macerals are more intimately mixed and at the same time are finer and more uniformly grained. Moreover cannel-coal frequently shows a uniform microstratification and is more homogeneous in structure than humic coals. Siderite is commonly abundant in cannel-coal. There is a continuous range of transitional stages between cannel-coal and boghead-coal with both alginite and miospores present. Intermediate types can be called boghead-cannel-coal and cannel-boghead-coal. British Geological Survey Research Report RR/99/03, section 6.2 and fig. 10.

Microstratification & siderite common. Microscopically macerals finer, more uniform & intimately mixed than in humic coal.	C
293	CAOCBT	Calciocarbonatite - A type of carbonatite. In the Rock Classification Scheme, this term may be used when a chemical classification is necessary because the rock is too fine grained for an accurate mode to be determined, or if the carbonate minerals are complex Ca-Mg-Fe solid solutions. The definition of calciocarbonatite is as shown in British Geological Survey Research Report RR/99/06, section 6.1 and figs. 25, 26. See also: calcite-carbonatite.

R	Cataclasite			GRBA	24-FEB-00	TMCM	22-FEB-19		Deformed (brittle), unfoliated rock with primary cohesion (protolith undefined) comprising 10-50% fragments in a finer grained matrix, grain size reduction by mechanical fragmentation +/- recrystallisation of matrix. Porphyroclasts monomineral fragments	C
305	CATR	Cataclastic-rock - A type of unfoliated mechanically broken rock with primary cohesion. These rocks are formed at higher confining pressures than those without cohesion. The nature of the rocks depends on factors such as confining pressure, original lithology, amount and duration of movement, and the availability of fluids. Cataclastic rocks exhibit grain size reduction by fragmentation of grains during deformation. In the Rock Classification Scheme, they are classified as protocataclasite, cataclasite, and ultracataclasite on the relative proportions of fragments and matrix. British Geological Survey Research Report RR/99/02, section 7.2 and table 4.	R	Cataclastic-rock			AWEL	12-MAY-00	TMCM	22-FEB-19		Deformed (brittle), unfoliated rock with primary cohesion (protolith undefined) comprising 10-50% fragments in a finer grained matrix, grain size reduction by mechanical fragmentation +/- recrystallisation of matrix.
