Abstract

Joints and other minor structural elements were recorded at 429 stations on the S. Gower coast. A systematic pattern exists comprised of up to 6 sets of joints which strike at 360°, 340°, 290°, 270°, 240° and 200°. Joint set maxima are frequently parallel to the strike of major and minor faults, but no simple geometric relationship exists between joint orientation and fold axis trend. Axial‐trace‐fracturing has been recognized, whilst en echelon gash arrays, mineralized joint sets and their cross‐cutting relationships enable a tectonic sequence of events to be determined. The systematic joints are thought to have developed during the folding under the influence of a N–S compression, but variation in the strike of minor structures suggests a swing in orientation of o through time. Subsequent stress relaxation facilitated dilation and the production of mineralized vein suites.

## 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 360°, 340°, 290°, 250°, and 210°. Minor faults and shear planes exhibit both strike and dip‐slip displacements. The

## Abstract Joints and faults were studied in Mesozoic and Avonian strata along 35 km of coast between Ogmore‐by‐Sea and Lavernock Point, Glamorgan, South Wales. Observations on joint and fault planes were recorded at 22 localities (i.e. approx. 750 stations), an analysis of which suggests the foll
