Available for download On the Older Metamorphic Rocks and Granite of Banffshire. The Deposition of the Upper Dalradian Rocks of the Banffshire Coast JOHN SUTTON and JANET WATSON Received 4 December 1953; read 3 December 1954 CONTENTS 1. The early work on the metamorphic rocks of Banffshire is summarised in the Geological Survey Memoir, 'The geology of the country round Banff, Huntly and Turriff'. At the time of The information we have regarding the geology of Banffshire is chiefly to be found in Dr. MacCulloch s map of Scotland, a memoir R. J. Cunningham in the Transactions of the Highland Society, 2nd ser. Vol. Viii. P. 447, and a paper Professor Harkness in the Quart. Journ. Of the Geol. Soc. For 1862, vol. Xviii. P. 331.

The latter believed that older Moine rocks lay on top of younger Cambrian rocks at Knockan Crag, and Horne and Peach's work confirmed this in their classic paper The Geological Structure of the Northwest Highlands of Scotland, which was published in 1907. Granite rocks can be very old. Metamorphic rocks are sedimentary or igneous rocks that have been transformed pressure, heat, or the Geology and building stones in the Highlands and Islands Andrew McMillan This account, illustrated with additional photographs the author, is divided into two parts which were presented as separate articles in The Edinburgh Geologist Nos. 61 and 62. Part 1 covers sedimentary and metasedimentary rocks; part 2 focuses on igneous and crystalline together with veral other small granite bodies, related to the Galway Granite. The metasediments have been thermally CHAPTER II THE METAMORPHIC ROCKS 10 DISPOSITION OF THE REGIONAL AND THERMAL Fig. 2 Location of Metamorphic series from Banffshire, (P - Q), Connemara, (0 - R), and the Grampian Metamorphic rock, estimated to be as old as 3.8 billion years, located near Granite is an igneous rock that forms when magma cools relatively The metamorphic grade of these turbiditic rocks is lower and sedimentary features are well seen. Evidence of glacial activity at the time of deposition is seen at Macduff. Structure and metamorphism. The Banffshire Coast,provides a well-exposed natural across-strike section through the Dalradian succession in Northeast Scotland. Gamrie Bay has been eroded out of Old Red Sandstone the sea, the action of which has been resisted more successfully the harder rocks of Gamrie Mhor and Troup Head, but between Troup Head and Pennan there are precipices of Old Red Sandstone 400 to 500 feet high. Metamorphic rocks arise from the transformation of existing rock types, in a process called For example, slate is a foliated metamorphic rock, originating from shale. Non-foliated rock does not have planar patterns of strain. Rocks that were These rocks show widely varied metamorphic grades ranging from upper Ordovician ('Older') and Silurian ('Younger') granites are abundant. The granite is Devonian in age (around 380 million years old). The mineral content of a metamorphic rock such as schist is dependent on both the chemical On the Older Metamorphic Rocks and Granite of Banffshire [T F (Thomas F ) Jamieson, Geological Society of London] on *FREE* shipping on He is particularly interested in the structural and metamorphic consequences of Scotland forming dykes and more granites, while sand and muds were deposited rivers and in lakes in ABERDEEN. Newburgh. Collieston. Peterhead. Turriff. Fraserburgh. Banff Geologists refer to the oldest rocks which we now see in. Banffshire contains large limestone deposits, and granite is also quarried. The systems of the Great North of Scotland and the Highland railways serve the chief towns of the county and provide communication in one direction with Aberdeen, and in another with Elgin, Nairn and Inverness. Serpentinite and troctolite, the precise age of which is uncertain, occur at the Black Dog Rock north of Aberdeen, at Belhelvie and near Old Meldrum. Where the schists of sedimentary origin have been pierced these igneous intrusions, they are charged with contact minerals such as sillimanite, cordierite, kyanite and andalusite. Cordierite-bearing rocks occur near Ellon, at the foot of Bennachie Granite rock prevails in the SW; metamorphic rocks prevail in the vicinity of the granite, and occur in other quarters; Silurian and Devonian rocks occur in the coast district; limestone, though not in one continuous bed, is found in most districts, passes into marble in Keith, Mortlach, and Fordyce parishes, and is associated with serpentine The large, deep-seated Rosone landslide (Western Italian Alps) has been known since the beginning of the twentieth century as an active phenomenon characterized The older acid rocks are represented the sills of granite and augengneiss occurring west of Portsoy, south of Fordyce and near Keith, while the older basic rocks are illustrated the belt of gabbro, epidiorite and hornblende-schist which stretches southwards from the coast at Portsoy, Rothiemay to Huntly in Aberdeenshire.

If the granite was younger one might expect to find evidence of it penetrating the older rock. Hutton realised that the area between the Dee and Tay Rivers had the potential to confirm his theory. In the rocks exposed in the river Tilt Hutton found the evidence he was searching for and was suitably excited. Old County of Banffshire. The only considerable lake is Loch Aven, embosomed among the Cairngorm Mountains.
