## Abstract Observations on joints, minor faults and mineral veins at 47 localities along the south and south east crop of the S. Wales Coalfield indicate the presence of a joint system comprised of up to 6 sets of fractures striking at 350Β°, 330Β°, 290Β°, 270Β°, 250Β° and 210Β°. The joint sets are para

β¦ Synopsis
Small-scale thrust faults are described from the North Crop of the South Wales Coalfield in strata of Avonian age. Two main sets occur which strike at east-west and north-south respectively. and show apparent stratigraphic zonation. It is suggested that the sets were initiated during the early stage of deformation of the area in response to primary and secondary resolved compressional forces.

## Abstract Joints, minor faults and mineral veins were recorded at 334 stations between Kidwelly and Black Mountain, S. Wales. A systematic pattern occurs with joint sets striking at 360Β°, 340Β°, 290Β°, 250Β°, and 210Β°. Minor faults and shear planes exhibit both strike and dipβslip displacements. The
## Abstract Three gravity traverses across the eastern half of the South Wales Coalfield indicate a local, elongate, negative Bouguer anomaly of a few milligals amplitude bordering the southern rim. The anomaly has a maximum amplitude of 4 mgal near Maesteg and attenuates eastward, dying out in the
