Psammite (Greek: psammitēs "(made) from sand", from psammos "sand") [1] is a general term for sandstone.It is equivalent to the Latin-derived term arenite [2] [3] and is commonly used in various publications to describe a metamorphosed sedimentary rock with a dominantly sandstone protolith. [4]
The oldest rocks within the area are those of the Tonian age Badenoch Group, [5] which occur along the northwestern edge of the national park. These rocks were formerly referred to as the Central Highland Division or Central Highland Migmatite Complex and have been included both within the Moine and Dalradian successions at various times.
In geology, metasedimentary rock is a type of metamorphic rock.Such a rock was first formed through the deposition and solidification of sediment.Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize.
The equivalent Greek-derived term is psammite, though this is more commonly used for metamorphosed sediments. Since it refers to grain size rather than chemical composition, the term is used for example in the classification of clastic carbonatic limestones, as the granulometrically equivalent term sandstone is not
The Badenoch Group is a sequence of metamorphosed Tonian age sedimentary rocks that outcrop across the Central Highlands of Scotland, east of the Great Glen.This rock sequence has formerly been referred to as the Central Highland Migmatite Complex and the Central Highland Division.
The ridge is prominently visible as the first line of foothills along the edge of the Great Plains. It is generally faulted along its western side, and varies in height, with gaps in numerous locations where rivers exit the mountains. The ridge takes its name from the Dakota Formation, a formation with resistant sandstone beds
The combination of high peaks and low prominence, means the ridges between the peaks are at a sustained height (e.g. why the prominence is so modest), which has contributed to the popularity of ridge walking in the Reeks, particularly, the Coomloughra Horseshoe, and the MacGillycuddy's Reeks Ridge Walk, and the term, "Ireland's highest mountain ...
The Southern Highland Group is a sequence of metamorphosed Neoproterozoic sedimentary rocks that outcrop across the Central Highlands of Scotland, east of the Great Glen.It forms the uppermost/youngest part of the Dalradian Supergroup and is divided into two formations.
