New data on the stratigraphy, structure and petrology of the Precambrian/Cambrian inlier at Martley, Worcestershire
A disused Victorian gravel pit [SO 7450 5956] 1 km west of Martley, Worcestershire formerly exposed an inlier of Neoproterozoic meta-igneous rocks and early Palaeozoic quartz arenite. The pit is back-filled, but trenching at the site between 2010 and 2014 re-exposed the rocks of the inlier and the surrounding Silurian and Carboniferous cover rocks. The site lies on the East Malvern Fault (EMF) and the work has proved the relationships between the meta-igneous rocks, quartz arenite and cover rocks, and revealed a complex of thrust faults in the footwall of the EMF. The thrusts are interpreted as footwall shortcuts and provide evidence of the Variscan inversion and compressive events resolved along this fault line (the Malvern Lineament) which has a prolonged and complex history of activation and reactivation. The structures at Martley provide a model in microcosm for other Variscan compressional structures along the Malvern Lineament.
期刊介绍：
The Proceedings of the Geologists'' Association is an international geoscience journal that was founded in 1859 and publishes research and review papers on all aspects of Earth Science. In particular, papers will focus on the geology of northwestern Europe and the Mediterranean, including both the onshore and offshore record. Following a long tradition, the PGA will focus on: i) a range of article types (see below) on topics of wide relevance to Earth Sciences ii) papers on aspects of Earth Science that have societal relevance including geoconservation and Earth management, iii) papers on palaeoenvironments and palaeontology of the Mesozoic and Cenozoic, iv) papers on aspects of Quaternary geology and climate change, and v) papers on the history of geology with particular reference to individuals that have shaped the subject. These topics will also steer the content of the themes of the Special Issues that are published in the PGA.
