The Path of Condie is a very old established collecting site. It is intruded by numerous dykes of micridiorite of Silurian/Devonian age which form a part of the North Britain Siluro-Devonian Calc-alkaline Dyke Suite. The Ochil Fault is the geological feature which defines the southern edge of the Ochil Hills escarpment in Scotland. Ochil Volcanic Formation and the Quaternary of Glen Devon August 9th 2003. Castle Campbell was built at the head of Dollar Glen in the late 15th century (an earlier castle on the site had been called "Castle Gloom") mainly as a very visible symbol of the Campbell domination of the area. The deepest deposits of coal measures are obviously found in this region, but this has not been mined to its full extent, probably due to the great depth involved. To put this in perspective, the prominent hill Dumyat which defines the western extremity of the Ochil Hills has a height of 418 metres. The plateau is undulating with no prominent peak, the highest point being Ben Cleuch at 721m The south-flowing burns have cut deep ravines including Dollar Glen, Silver Glen and Alva Glen, often only passable with the aid of wooden … References: British Geological Survey Photographic Archive (website) Francis, E.H. A notional boundary for the Ochil Hills is shown in Map 2, bounded by roads, and stretching from Dunblane in the west to Glen Farg in the east. The Ochil Fault has produced one of the best examples of a fault line scarp to be seen in Britain. Fault Scarp - Ochil Hills The line of the Ochil Fault can be traced across this image, which shows the sheer scarp slope of the Ochil Hills rising up over the downthrown plain below. The minerals, including ores of silver and cobalt, were probably emplaced by hydrothermal solutions percolating upwards through various minor faults and fractures, in the Tertiary period. Our latest film, narrated by Dr Kirsty McAlister, explores the various ways in which people's lives have been influenced by the Ochil Hills. In what was called "the fairest portion of the northern kingdom" by Sir Walter Scott, Gleneagles, the glamorous 850-acre retreat set beneath the Ochil Hills of Scotland in the heart of Perthshire, is introducing a trio of new meeting & events spaces for jaw-dropping gatherings.

Castle Craig, a ruined ancient fort above the village of Mill Glen destroyed by industrial quarrying, was mentioned by local historian William Gibson in 1883 as being "a round Pictish fortress, the traces of which can still be distinctly seen. Glacial till covers much of the lower ground around and within the range and peat accumulations occur on the plateau surface particularly in the west.[7]. Path of Condie and the Ochil Hills The andesitic lavas continue in a broad arc around Perth, and agate bearing localities are found to the south-west around the Path of Condie and along the southern face of the Ochil Hills. Peaks over 3,000 ft (914.4 m) are known as Munros. [3], The Ochils are formed from a thick wedge of Devonian age volcanic and volcano-sedimentary rocks, rising up from below the lower Old Red Sandstone sedimentary rocks to the north and terminated to the south by the major southerly downthrowing Ochil Fault. Edinburgh : HMSO, 1970 The plateau is undulating with no prominent peak. [6] Parts of the lower slopes on the northern side around Blackford and Auchterarder are formed from a volcanic conglomerate. The Ochil Faultis the geological feature which defines the southern edge of the Ochil Hillsescarpment, Scotland. The Ochil Fault was active from the earliest part of the Carboniferous period, allowing the marine swamps in which the coal-producing vegetation flourished to be periodically overlain by layers of sand, forming sandstone, or silt, forming shale, in a number of cyclic subsidences. These occurred in the form of basins, and the pattern of movements was complex, however it is known that the greatest vertical movement was centred about 1 km east of the town of Alva, and almost certainly exceeded 5 km vertically. The extent of the Ochils is not well-defined but by some definitions continues to include the hills of north Fife.[3]. Mountains in Scotland are categorised by their height. Modern movements of the fault are very minor but occasionally give rise to discernible earthquakes,[3] particularly in the village of Menstrie, and the town of Tillicoultry. North of the fault, The geology of the Stirling district. There were several excellent locations but the most productive, Borland Glen (7), yielded gold with a distinctive telluride signature in … There has also been swarm activity in the Central Valley of Scotland by the Ochil Hills (near Stirling). The Ochil Fault remained active throughout geological time, and some later movements allowed intrusive eruptions of diorite or quartz-dolerite to rise at various places along its length. Boyle, R. W., 1962, Geology of the Barite, Gypsum, Manganese, and Lead Zinc-Copper-Silver Deposits of the Walton-Cheverie Area, Nova Scotia: Geological Survey of Canada, Paper 62-25, 26 p.

The Ochil Fault is one of Britain's finest examples of a fault line scarp,[4] and can be best appreciated from vantage points such as the Wallace Monument near Stirling. The formation comprises over 2000m of subaerial basaltic and andesitic lava flows with interbedded terrestrial debris-flow conglomerates. These are in part overlain by Old Red Sandstone rocks formed later in the Devonian period. [2] The nearest colliery, Manor Powis, approximately 2 km south of the fault, was approximately the same depth, in carse land that is scarcely above sea level, and was mining coal from Carboniferous strata at least many hundreds of metres above the top of the Devonian deposits.
