Note secondary porosity (V) composed of channels and vughs that feature secondary calcite carbonate growth. XPL; width of photo is ca. mm. DISCUSSION It has not been an easy task to reconstruct the sedimentary history of Gough's Cave, because the micro-sedimentary evidence by neces- sity, has been gathered from the small (max. 40 mm thick) pockets of sediment that remain on the extreme edges of the main cave, and the mainly early Holocene sequence in the Sand Hole. The sequence at Gough's is quite localized and built up from non- continuous exposures within the cave, and so must be considered as yielding only a partial history of the cave. The sedimentary sequence commences with the deposition of the conglomerate, followed by sands and gravels that fine upwards to the red silts, with muds being restricted only to the Sand Hole (Table 1). This Late Glacial accumu- lation lasted from about 12,000 to 10,500 l4C years bp, and seems to be roughly correlated with the Windermere Interstadial (ca. 13,000 to 11,000 l4C years bp) through to the Loch Lomond Stadial (11,000 to 10,000 14C years bp). Human skeletal remains occurred within the red silts and were variably coated with silty clay through to sand and fine gravel (Currant and Stringer, NHM, pers. comm.). The bones (Stringer, 2000) that date to ca. 13,000 to 11,500 radiocarbon years ago would thus appear to be in situ and contemporary with the lower energy deposition of the upward fining sequence. This phreatic period appears to be contemporary with both Upper Palaeolithic activity and the Windermere Interstadial (Table 2). The formation of the conglomerate can perhaps be best related to.
