DIC_ROCK_ALL (3677 rows)
Dictionary table based on the entire version 3 of the BGS Rock Classification Scheme and is populated directly from the 3 supplying tables (BGS.ROCK_NAME_V3, BGS.ROCK_COMPOSITE and BGS.DIC_ROCK_DUMMY). It contains both the base rock names and addditional codes required for specific application, eg. composite names for use on digital geological maps. It is formally approved as the official source of ALL database codes to be used in BGS corporate databases and MUST be followed.

| 2519 | OGNSS | RN | Orthogneiss - A type of meta-igneous rock based on textural attributes. In the Rock Classification Scheme, it is defined as a medium- to coarse-grained inhomogeneous rock, commonly with a well-developed preferred orientation of constituent minerals, and characterised by a coarse foliation or layering that is more widely spaced, irregular or discontinuous than that in a schist. Adjacent layers generally exhibit contrasting texture, grain size, and mineralogy. However, there is a continuum between schists and gneisses, with factors such as the spacing of the foliation and the degree of contrast between adjacent layers contributing to the assignment of a rock to either category. Gneiss is distinguished from schist where some layers are over 5 mm thick. Gneisses generally occur in areas of middle to upper amphibolite or granulite facies metamorphism and can encompass a wide range of lithologies. Note the ortho- prefix indicates a rock that is thought to have an igneous protolith, in contrast with paragneiss which has a sedimentary protolith, and gneiss where the nature of the protolith is not defined.
