The BGS Rock Classification Scheme (RCS) is a corporate standard setting out a practical, logical and robust system for classifying and naming geological materials as they appear at the scale of a single exposure, hand specimen, or thin section.
Classification helps to place materials in a wider geological context, and allows unambiguous and informative formal names to be assigned.
The RCS provides a comprehensive system for classifying and naming geological materials to act as a corporate standard in support of our digital geological maps, data dictionaries, and numerous other modern geological applications.
In addition to the four rock classification volumes, a scheme for the classification of discontinuities is now available.
|Volume 1||Igneous rocks 663KB pdf||more...|
|Volume 2||Metamorphic rocks 260KB pdf||more...|
|Volume 3||Sediments and sedimentary rocks 459KB pdf||more...|
|Volume 4||Artifical man-made ground and natural superficial deposits 3.1MB pdf||more...||BGS scheme for classifying discontinuities and fillings 4.04MB pdf||more...|
The rapidly increasing use of computers to store geological information and the production of maps from these databases has also driven the formulation of these schemes. Computers can integrate data very rapidly from a wide range of sources from properly constructed databases but it is vital that the data are input with a consistent meaning. This requires a clearly defined comprehensive rock classification scheme with master dictionaries of all the approved rock names.
