“…In the east, the outwash terraces in the Kelvin/Carron valleys merge with fossil shorelines in the Forth that have been described and interpreted in Sissons and Smith (1965). In the west, fossil shorelines are developed along the Clyde and the Gareloch, and in the Leven Valley and Loch Lomond (Dickson et al, 1978). Nearly all these shorelines are eroded into ORS bedrock or till, and all are associated with well sorted beach deposits which often form beach ridges.…”

This paper presents a 1:25,000 scale geomorphological map of the Glasgow region, western central Scotland, an area that was glaciated during the Last Glacial Maximum and, in part, during the Younger Dryas glaciation. The text accompanying the map sets out the historical context of the mapping exercise and describes the process of geomorphological mapping at 1:10,560 scale. The text outlines briefly the results of the mapping exercise, in terms of the map evidence recorded and the interpretation of Quaternary landscape evolution. The paper is not designed to provide a comprehensive review of the geomorphology and Quaternary history of the area which can be found in the references cited therein.

“…Kjemperud, 1986;Svendsen and Mangerud, 1987; Bjorck and Digerfeldt, 19911, there has been little concentration on isolation basins in Scotland. Loch Lomond and Loch Shiel are two large basins (each over 25 km long) which have alternated between fresh and marine-brackish conditions during the Holocene (Dickson et a/., 1978; Thompson and Wain-Hobson, 1979). Loch Cill Chriosd, Isle of Skye, is a smaller (1.5 by 0.5 km) basin, and records a relative fall in sea-level during the Late Devensian (Birks, 1973; Birks and Williams, 1983;Walker and Lowe, 1991 1.…”

Pollen, diatom, radiocarbon and lithostratigraphical data from isolation basins in northwest Scotland are used to quantify the reference water (tide) level, indicative range and age of different types of isolation and connection contacts. Tendencies of sea-level movement and relative sea-level changes from the mid-Lateglacial lnterstadial (1 1.8 ka BPI to the late Holocene are constructed from these data.Relative sea-level fell continuously from +17.8 m O D at 11.8 ka BP to ca. +5.2 m OD at 10.1 ka BP. From an unknown minimum between 10 ka and 9 ka BP relative sea-level then rose to f6.3 m O D at 8.3 ka BP. The maximum Holocene sea-level occurred within the range $6.6 m OD to +9.3 m OD between 6.6 ka BP and 4.0 ka BP before falling to present. Isobase, age-altitude and quantitative rebound models for northwest Scotland are tested using these sealevel data, but none of the published models shows close agreement with the new results.Journalof Quaternary Science

SUMMARYA sequence of lake muds and fen peat deposits from Loch a'Mhuilinn, north Arran, contains evidence for the local vegetation history for parts of the Flandrian Interglacial. The main components of this history are as follows:Sedimentation occurred under open-water conditions during early Flandrian times. By around 5000 B.P., fen peat was accumulating, and during the 2nd millenium B.P., an unexplained reversion to open-water conditions occurred.The earliest recorded vegetation immediately predates the Corylus rise and is characterized by Betula-rich woodland with Juniperus and Salix being present in places. The Corylus rise, occurring at around 8600 B.P., marks the beginning of a period of Corylus-r'ich Betula woodland. Subsequent increases of Ulmus, Quercus, Pinus and Alnus pollen represent further forest development. Fluctuations in the composition of this mixed forest are recognized, as can a distinction between areas of Betula-Quercus, Corylus-v'ich and Alnus-rich. woodland.At around 5000 B.P., the vegetational development, previously representing broad regional changes, appears to respond to local processes. Fluctuations in the proportions of trees and Gramineae pollen may reflect vegetational disturbance, although sedimentation processes may be influencing the pollen deposition at this time. This period is followed by apparently greater woodland stability, with minor indications of human activity. By around 4000 B.P., early stages of Calluna-rich heath are apparent. The development of the heath vegetation is not recorded, but by the 2nd millenium B.P., Calluna heath and grassland appear to be well established in north Arran.The history of Sorbus spp. is examined in as much detail as the fossil evidence allows. By around 6500 B.P., Sorbus aucuparia L. is present in the area, and by around 5400 B.P., evidence for non-aucuparia Sorbus species is present. This evidence may represent the former presence of 5. rupicola (Syme) Hedl. and/or one or both of the two endemic species S. arranensis Hedl. and 5. pseudofennica E. F. Warb.
