A president of the Geological Society from 1815 to 1817, he is best remembered for producing the first geological map of Scotland, published in 1836. ' MacCulloch's Tree ', a 40-foot (12 m) high fossil conifer in the Mull lava flows, is named after him.
The geology of Ohio formed beginning more than one billion years ago in the Proterozoic eon of the Precambrian. The igneous and metamorphic crystalline basement rock is poorly understood except through deep boreholes and does not outcrop at the surface. The basement rock is divided between the Grenville Province and Superior Province.
The geology of the Highlands is complex. Along the western coastal margin it is characterised by Lewisian gneiss, the oldest rock in Scotland. Liathach, Beinn Alligin, Suilven, Cùl Mòr, Cùl Beag, and Quinag are just some of the impressive rock islands of the significantly younger rich brown-coloured Torridonian sandstone which rests on the ...

Geological map of the Hebridean terrane showing distribution of rocks of the Lewisian complex Undeformed Scourie dyke cutting Lewisian Gneiss, about 1.6 km west of Scourie Scourie dykes (now foliated amphibolites) cutting grey gneiss of the Scourie complex, both deformed during the Laxfordian tectonic event and cut by later (unfoliated) granite veins - road cutting on the A838 just north of ...
The geology of Great Britain is renowned for its diversity. As a result of its eventful geological history, Great Britain shows a rich variety of landscapes across the constituent countries of England, Wales and Scotland. Rocks of almost all geological ages are represented at outcrop, from the Archaean onwards.
The main geographical divisions of Scotland. The Central Lowlands, sometimes called the Midland Valley or Central Valley, [1] is a geologically defined area of relatively low-lying land in southern Scotland. It consists of a rift valley between the Highland Boundary Fault to the north and the Southern Uplands Fault to the south. [2]
The geography of Scotland is varied from rural lowlands to unspoilt uplands, and from large cities to sparsely inhabited islands. Located in Northern Europe, Scotland comprises the northern part of the island of Great Britain as well as 790 surrounding islands encompassing the major archipelagos of the Shetland Islands, Orkney Islands and the Inner and Outer Hebrides.
