Ochil Volcanic Formation and the Quaternary of Glen Devon August 9th 2003. The Ochil Hills (/ˈoʊxəl/ (listen);[1] Scottish Gaelic: Monadh Ochail[2] is a range of hills in Scotland north of the Forth valley bordered by the towns of Stirling, Alloa, Kinross, Auchterarder and Perth. To the NE, the scarp of the West Ochil Fault, one of the most spectacular in the Midland Valley, is well seen. Alluvial gold is wide-spread and locally abundant in the central Ochil Hills, but the bedrock sources have not been identified. Ochil hills over 600m PDF. 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. The Path of Condie is a very old established collecting site. 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]. The geology of the Stirling district. [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. 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. Mining and Minerals This project showcases the importance of the industrial heritage in the Ochils area's development, which is closely linked to its geology. Such ranges include the Ochil Hills, near Stirling, the Campsie Fells outside Glasgow, and the Lomond Hills in Fife. Northern Ochil hills PDF. Black Hill (North-West) near Sherrifmuir is marked on OS Maps as “Black Hill", but has no distinguishable peak or summit, more of a slop leading onto Glentye Hill. The plateau is undulating with no prominent peak. THE GEOLOGY OF THE COUNTRY ROUND STIRLING. The Ochil Fault, one of the most prominent tectonic features in the Midland Valley of Scotland, juxtaposes Lower Devonian volcanic rocks against late Westphalian strata, implying a possible vertical displacement of … North of the fault, The Ochil Faultis the geological feature which defines the southern edge of the Ochil Hillsescarpment, Scotland. Marked as 350 metres. The whole massif is heavily faulted with some valleys such as Alva Glen and Glen Sherup having been eroded along these lines. 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.

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. Historically, the hills, combined with the town's site at the lowest bridging-point on the River Forth, led to Stirling's importance as a main gateway to the Highlands. The only major roads crossing the hills pass through Glen Devon/Glen Eagles and Glenfarg, the latter now largely replaced except for local traffic by the M90 Edinburgh-Perth motorway cutting through the eastern foothills. Since 1846 small shocks have been observed at Comrie on a regular, if infrequent, basis. Geography and geology The hills are part of a Devonian lava extrusion whose appearance today is largely due to the Ochil Fault which results in the southern face of the hills forming an escarpment. Some of the mills are open today as museums. The Ochil Fault, one of the most prominent tectonic features in the Midland Valley of Scotland, juxtaposes Lower Devonian volcanic rocks against late Westphalian strata, implying a possible vertical displacement of … We take a look at the early Iron Age settlement on Dumyat, the possible medieval hunting lodge behind Castle Campbell in Dollar, the Ochils' contribution to local industries - not least textiles, urbanisation, and recreation.

Berry Hill and The Shank (near NN 9591 0456) are marked as hills on OS maps, but fail to have distinguishable peaks. [5], The Ochil Volcanic Formation, a sub-unit of the Arbuthnott-Garvock Group, consists of basaltic andesite and trachyandesite lavas and related rock types erupted during the Early Devonian epoch. The south-flowing burns have cut deep ravines including Dollar Glen, Silver Glen and Alva Glen, often only passable with the aid of wooden walkways. [10] The windfarm is owned and run by EDF Renewables, who support the work of the Ochils Mountain Rescue Team through the Burnfoot Hill Community Fund with an annual donation of £5,000 guaranteed till 2039. 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.

Alluvial gold is wide-spread and locally abundant in the central Ochil Hills, but the bedrock sources have not been identified. It continues for about 9 miles along the southern edge of the Ochil Hills, from Blairlogie in the west to past Dollar in the east.
