A hand specimen of Eclogite - a high temperature, high pressure, metamorphic rock formed at great depth, ~ 45 km, at the junction between the lithosphere and the mantle. The red garnet (almandine) and the green pyroxene (omphacite) make this rock particularly striking. Width of specimen: 9 cm. Provenance of specimen: unknown (from rescued, unwanted, university teaching collection) :-(

This is the Near Hearkening Rock, an overhanging outcrop of Upper Devonian Quartz Conglomerate, in High Meadow Woods, an outlier of the Forest of Dean. It is so called because you are supposed to be able hear distant sounds (such as conversations or the horse hooves of an approaching army) which are amplified by the shape of the rock outcrop.

The Buck Stone is a remnant edge tor comprised of the Quartz Conglomerate - the basal part of the upper Old Red Sandstone (Devonian). These cross-bedded sediments were deposited in alluvial fan or flash flood deposits, mostly in high-energy rivers draining an arid, mountainous continental area. There are many quartz pebbles, hence the name, but also rock fragments and more exotic pebbles such as jasper, all set in a medium - coarse sand matrix. Although in located in Gloucestershire, England, the Welsh border is very close by, at the bottom of the slope.

The fields in the middle distance and the far landscape are entirely in Wales.

Originally posted for the Sheffield Guesswhere Group. This is the excavation for what is now the A57 dual carriageway Beighton bypass, south-east Sheffield. The rock face in the picture is made of well-jointed Woodhouse Rock, a sandstone unit in the Coal Measures (upper Carboniferous). See where this picture was taken. [?]

Originally posted for the Guesswhere UK group. This is the boulder at Copt Howe in Great Langdale, just west of Chapel Stile. At its base are what are thought to be Neolithic rock carvings, possibly depicting the location of the Langdale Axe 'factory' on Pike o' Stickle.
