. See the
main article on faults for a fuller treatment of fault types and nomenclature but in brief, the main types are normal faults, reverse faults, thrusts or thrust faults and strike-slip faults. Many faults may have acted as both normal faults at one time and as reverse or thrust faults at another and may or may not have also incorporated some degree of strike-slip movement too. Fault zones, fault belts and fault complexes typically describe assemblages of faults which have a common origin and history and whose alignments tend to be sub-parallel to one another.
There are also a number of
'disturbances', notably in
South Wales
South Wales ( cy, De Cymru) is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards ...
. These linear features are a combination of faults and
folds - the relative importance of faulting and folding varying along the length of each disturbance.
Key to tables
*Column 1 indicates the name of the fault. Note that different authors may use different names for the same fault or a section of it. Coversely the same name may be applied to more than one fault, particularly in the case of smaller faults which are widely separated. Names are as they appear in the literature and do not necessarily conform to the commonly accepted modern spelling or form of the place-names with which they are associated.
*Column 2 indicates the OS grid reference of the approximate midpoint of certain faults. Note that the mapped extent of a fault may not accurately reflect its actual extent.
*Column 3 indicates the
county

in which the fault occurs. Some traverse two or more counties of course.
*Column 4 indicates on which sheet, if any, of the

's 1:50,000 / 1" scale geological map series of England and Wales, the fault is shown ''and'' named (either on map/s or cross-section/s or both). Also listed are a handful of BGS maps at other scales, where the fault is both shown and named.
*Column 5 indicates a selection of publications in which references to the fault may be found. See references section for full details of publication.
