The Alveston Bone Fissure is the remnant of a cave system. Stalagmite was formed on the basal silt. Later boulder falls opened the roof of the cave to the surface and it became a pitfall for animals during the eemian inter-glacial. The bone-bearing cone of dejection was truncated by erosion followed by deposition of thermoclastic scree, presumably of Weischelain age, and finally by post-glacial red loam. The site was mined for lead and quarried in the 1750s. Excavations were made in 1960-1963. A report on the soils forms part 2.

An attempt is made to describe these collections in general terms and to assaess their significance. The collections have been derived from surface finds. There have been no excavations. The periods represented by the typology of the implements range from Late Upper Palaeolithic/Mesolithic through Neolithic to Bronze Age.

In 1968 the surface stream, cave stream and certain drip inlets of G.B. Cave, Somerset, were studied. Chemical and physical charcteristics were measured weekly from February until the great flood of 10th July 1968 and irregularly for the rest of the year. This paper presents statistical summaries of site charcteristics and their inter-relationships and a statistical examination of measurements of limestone solution between the surface swallet and the cave. Several smaller sections discuss the relevance of the results to a number of different branches of limestone studies, such as temperature variations in drip inlets and the significance of infilled depressions in the drainage of limestone on the Mendip Hills. Some hydrological side-effects of the July flood are also examined.

The area of the central Burren including Aillwee Hill and the Kilcorney-Carran closed depressions is charcterised by a series of dry valleys and closed depressions, often with remnants of ancient phreatic caves preserved. These features may have been developed since Pliocene times by runoff from the former shale cover together with later modification by glacial and periglacial activity.
