Clava Cairn
The Clava cairn is a type of Bronze Age circular chamber tomb cairn, named after the group of three cairns at Balnuaran of Clava, to the east of Inverness in Scotland. There are about 50 cairns of this type in an area round about Inverness. They fall into two sub-types, one typically consisting of a corbelled passage grave with a single burial chamber linked to the entrance by a short passage and covered with a cairn of stones, with the entrances oriented south west towards midwinter sunset. In the other sub-type an annular ring cairn encloses an apparently unroofed area with no formal means of access from the outside. In both sub-types a stone circle surrounds the whole tomb and a kerb often runs around the cairn. The heights of the standing stones vary in height so that the tallest fringe the entrance (oriented south west) and the shortest are directly opposite it. When Clava-type tombs still contained burial remains, only one or two bodies appear to have been buried in each, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring Cairn
A ring cairn (also correctly termed a ring bank enclosure, but sometimes wrongly described as a ring barrow) is a circular or slightly oval, ring-shaped, low (maximum 0.5 metres high) embankment, several metres wide and from 8 to 20 metres in diameter. It is made of stone and earth and was originally empty in the centre. In several cases the middle of the ring was later used (at Hound Tor, for example, there is a stone cist in the centre). The low profile of these cairns is not always possible to make out without conducting excavations. Distribution These sites date to the Bronze Age and occur in Cornwall, Derbyshire ( Barbrook IV and V and Green Low) in England; and in Scotland, Wales and Ireland. Description The cairns look like flat variants of the significantly higher Clava cairns, which are often called ring cairns by laymen. The situation is rather different on the gritstones of the Eastern Uplands. Here it is more common to find smaller stone circles and rin ...

Stones And Cairn
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existing rocks. M ...
