Fife and Angus Geology was first published in 1968, a second edition appearing in 1973. These early editions owed much to the encouragement of the late Professor C. F. Davidson and the critical appraisal of R. Johnston, both of the St Andrews University Geology Department.
By 1985, however, Fife and Angus Geology was out of print and much new work on the geology of the area had been published. The opportunity was therefore taken to re-write completely the introductory chapters, incorporating new information into all the itineraries, omitting from the guide book the excursions to the area between Stonehaven and Aberdeen and to South Queensferry since both are very well covered by the Aberdeen and Lothian guides respectively, and combining or modifying some of the previous itineraries. Two new itineraries have resulted, one for the North Fife Hills and the other for the area lying between Dundee and Perth.
Over the years gentle but persistent encouragement to produce a new edition came from Douglas Grant and many other friends and colleagues and I am grateful to them all for this, as I am to my wife for reading and rereading the manuscript over a considerable period. The manuscript was put on the word processor by Sue Canfield and Margaret Connolly with patience and understanding. The maps and tables were entirely redrafted or are new, the work of Graeme Sandeman and Janet Mykura of the Cartographic and Graphic Services of the School of Geography and Geology, University of St Andrews.
Scope of the guide and further references
The whole-day and half-day excursions are designed to illustrate the geology of the area. Most of them are or were excursions run from the Department of Geography and Geology, St Andrews University. Two can be reached from St Andrews on foot; the remainder require transport and in a number of cases it is helpful to be dropped at one point and picked up at another.
References to the appropriate maps and literature are included with each itinerary, but for the area as a whole the 1/250,000 Tayforth Solid Geology Sheet 56N 04W of the British Geological Survey is useful. One-inch to the mile or 1/50,000 Geological Survey maps are available for most of the area and are listed at the beginning of each itinerary with the prefix GS. Six-inch to the mile or 1/10,000 geological maps of some of the coalfields are published; others are available for inspection at the office of the British Geological Survey in Edinburgh. Out of print maps may also be consulted there. Ordnance Survey maps are also listed for each itinerary with the prefix OS and refer to the 1/50,000 maps of Scotland.
The British Regional Geology Handbooks The Midland Valley by I. B. Cameron and D. Stephenson (1985) and The Grampian Highlands by G. S. Johnstone (1966), both published by HMSO, contain abundant references and are revised from time to time. For a treatment of the whole country the Geology of Scotland edited by G. Y. Craig (1991) is comprehensive and has long lists of references. Readers not familiar with geological terminology are referred to the Penguin or other geological dictionaries. The names of fossils have been kept to an elementary level deliberately in the belief that names such as Productus are more meaningful to the non-specialist. Full faunal lists for most of the fossil localities in Fife are to be found in the publications of the Geological Survey, e.g. Geology of East Fife (Forsyth and Chisholm 1977).
Map 1 indicates the location of the 18 excursions. Coastal excursions almost all require mid- to low tide and for Excursion 15 (Kincraig) low tide is essential for access.
To determine the time of high tide on any particular day, note how many days after new moon or full moon it is. New moon is marked on the chart as day zero and full moon as day 15. Then read along the bottom of the chart to the day in question and follow the column up. The time of high tide lies between the two heavy black lines which cross the chart obliquely. Spring tides, those with the greatest range, occur approximately 2 days and 16 days after new moon; while neap tides, those with the least range, occur approximately 9 and 23 days after new moon.
- High tide is 60 minutes earlier at Stonehaven.
- High tide is 50 minutes earlier at Fife Ness.
- High tide is 40 minutes earlier at Methil.
More precise times can be obtained from the Admiralty Tide Tables.

The eighteen excursions in the guide are designed to cover the salient features of the geology of the area extending north from Kinghorn to Stonehaven. They are numbered from north to south and are intended as whole day and half day excursions, the approximate timing being indicated with each itinerary. Each excursion is illustrated by one or more maps on which the localities to be visited are indicated by numbers. There is a brief description in the text for each locality and each itinerary starts with an indication of the walking distance, purpose of the excursion and the route from St Andrews to the area to be examined.
The section on the geology of the area indicates which excursions serve to illustrate the different aspects of the geology. Metamorphic rocks can be seen on Excursions 2 and 4, and the Highland Boundary Fault together with the Highland Border Complex on Excursions 1 and 2. Among igneous rocks, plutonic rocks can be seen on Excursion 4, sills on Excursions 3, 8, 16, 17 and 18; dykes on Excursions 1, 2, 3, 10, 13, 14 and 15; while lavas are well exposed on Excursions 3, 5, 7 and 18. Volcanic necks are abundant in Fife and are magnificently exposed on the coast; they can be examined to advantage on Excursions 7, 10, 13, 14, 15 and 16.
Sedimentary rocks can be seen on almost all the excursions, those of the Lower Old Red Sandstone on Excursions 1, 2 and 3 in particular. The Upper Old Red Sandstone can be seen on Excursions 1, 8 and 17 mainly; the lowest Carboniferous on Excursions 9, 10, 11, 12, 13 and 17 and the Carboniferous Lower Limestone Formation on Excursions 12 and 18. Quaternary sediments are well displayed on Excursions 3 and 6.
A number of itineraries lead over high ground and these provide good views of the regional geology extending over the north-east part of the Midland Valley of Scotland. Such views are found on Excursions 3, 7, 16 and 17.
Two excursions are particularly suitable as introductory ones. Excursion 9 introduces common sedimentary rock types plus folding and faulting, while Excursion 10 displays particularly straightforwardly volcanic necks and their stages of development.
Which excursions anyone will choose will depend on their interests and time available together with the state of the tide since many excursions are inter-tidal, but the remarks of Sir Archibald Geikie, then Director of the Geological Survey, remain apposite: 'If I were asked to select a region in the British Isles where geology could best be practically taught by constant appeals to evidence in the field, I would with little hesitation recommend the East of Fife as peculiarly adapted for such a purpose. Every teacher of the science appreciates the value of a shore-section where the rocks have been dissected and washed clean and bare by the tides. Round its long stretches of coast-line, the East of Fife presents an almost continuous succession of such sections which for variety, instructiveness, and accessibility have hardly any rivals in the country.' (Geikie, 1902, p iv).
