27 +#~IPN  Meta-igneous rock based on protolith name - In the Rock Classification Scheme, a meta-igneous rock is classified within this category if its igneous protolith is clearly recognisable. British Geological Survey Research Report RR/99/02, section 5.1 and fig. 1. See also: igneous rock and sediment.  A  Meta-igneous rock based on protolith name          AWEL  22-JUL-02  TMCM  22-FEB-19    Not Available  C 
28 +#~IR  Meta-igneous rock - In the Rock Classification Scheme, a rock is classified within this category if it is considered to be a metamorphic rock derived from an igneous protolith, either because of its lithological characteristics (i.e. preservation of igneous textures and in some cases composition or mineralogy) or its lithological associations. The class includes meta-igneous rock based on protolith name, meta-igneous rock based on modal composition, and meta-igneous rock based on textural attributes. British Geological Survey Research Report RR/99/02, section 5 and fig. 1.  A  Meta-igneous rock          AWEL  08-MAR-00  TMCM  22-FEB-19    Not Available  C 
29 +#~MOD  Meta-igneous rock based on modal composition - In the Rock Classification Scheme, a meta-igneous rock is classified within this category if it cannot be classified according to protolith name. The class includes metafelsic-rock, metamafic-rock, and meta-ultramafic-rock. They are distinguished on the relative proportions of quartz, feldspar, and mafic minerals. Muscovite, carbonate and other generally pale-toned minerals are considered neutral and not used in the modal classification.

This class includes orthoschist, orthogneiss, and orthogranofels. British Geological Survey Research Report RR/99/02, section 5.3 and fig. 1.  A  Meta-igneous rock based on textural attributes          AWEL  09-MAR-00  TMCM  22-FEB-19    Not Available  C 
31 +*CSSR  Carbonate sediment and sedimentary rock - In the Rock Classification Scheme, carbonate sediments and rocks are defined as rocks in which the carbonate component forms more than 50% of the sediment or rock. For a rock to be termed a carbonate sedimentary rock, the 50% carbonate criterion should not include any carbonate cement in an originally non-carbonate rock. The class is divided into lime-sediment and limestone, dolomite-sediment, dolostone and magnesite-stone, and Na carbonate sedimentary rock, defined on the basis of the carbonate composition.

37 +*NCSS  Non-clastic siliceous sediment and sedimentary rock - In the Rock Classification Scheme, these are rocks and sediments which are composed of more than 50% silica of biogenic or chemical origin. The classification is based upon the stage of the mineralogical transformation of silica, the type of silica and, if recognisable, the type of biogenic matter. British Geological Survey Research Report RR/99/03, section 8 and fig. 12.  A  Non-clastic siliceous sediment and sedimentary rock          AWEL  08-MAR-00  TMCM  08-MAR-19    Not Available  C
