Inishtrahull
Inishtrahull ( ga, Inis Trá Tholl, possibly "island of the empty beach" or "island of the yonder beach") is the most northerly island of Ireland. It has an area of and lies about northeast of Malin Head, County Donegal. The most northerly landfall of Ireland, the Tor Beg rock, is another kilometre to the north. Inishtrahull is home to Ireland's northernmost lighthouse. The island had a resident community until 1929 and the lighthouse was staffed until 1987. Today it is uninhabited and has been designated a protected area due to its wildlife. Geology The island is formed of a granitic gneiss, a type of metamorphic rock, which is known as Inishtrahull Gneiss. It is dated at 1.7 billion years old, making it Paleoproterozoic in age, and is the oldest known rock on the Irish Islands. The Inishtrahull Gneiss is considered to form part of the Rhinns complex that is also exposed on the islands of Islay and Colonsay. The Rhinns complex is correlated with the Ketilidian metamorphic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inishtrahull Lighthouse
Inishtrahull Lighthouse is the northerly most lighthouse in Ireland located on the Inishtrahull Island off the coast of County Donegal. Coupled with the lighthouse on Tory Island they form the two main landfall lights for shipping from the Atlantic rounding the north coast of Ireland, and navigation to local shipping. Work on the first lighthouse, situated at the east end of the island began in 1812, primarily due to Royal Navy ships using Lough Foyle. Designs for the lighthouse were drawn up by a George Halpin, a Senior Inspector of Lighthouses. Acting on behalf of the Corporation for Preserving and Improving the Port of Dublin. The first Light was established on 17 March 1813. The height of the tower was approx. 12.8 metres. Later a dioptric apparatus was installed in the tower and came into operation on 29 September 1864. At the start of the 20th century, it was decided that a fog signal was required in the area of Malin Head. It was decided that it would be constructed at ...

Rhinns Complex
The Rhinns complex is a deformed Palaeoproterozoic igneous complex that is considered to form the basement to the Colonsay Group of metasedimentary rocks. The largest outcrop of the complex is on the Rhinns of Islay, from where the complex gets its name. It has also been recognised in three other inliers extending to the southwest as far as Inishtrahull, off the north coast of Donegal. Distribution The Rhinns complex has been recognised in a series of four outcrops that form inliers within younger cover sequences of the Dalradian Supergroup and the Colonsay Group. The most easterly of these exposures is on the islands of Colonsay, where the complex consists of strongly retrogressed orthogneisses, although the correlation of this outcrop with the Rhinns complex has been questioned on the basis of new radiometric dating and Hf isotope analyses. On the Rhinns of Islay, gneisses of the Rhinns complex lie unconformably beneath the Colonsay Group, which is correlated with the ...

Malin Head
Malin Head ( ga, Cionn Mhálanna) is the most northerly point of mainland Ireland, located in the townland of Ardmalin on the Inishowen peninsula in County Donegal. The head's northernmost point is called Dunalderagh at latitude 55.38ºN. It is about 16 km (10 mi) north of the village of Malin. The island of Inishtrahull is further north, about 10 km (6 mi) northeast of the headland. Malin Head gives its name to the Malin sea area. There is a weather station on the head, which is one of 22 such stations whose reports are broadcast as part of the BBC Shipping Forecast. A tower built in 1805 is on Altnadarrow, also known locally as the Tower Hill. Ptolemy's ''Geography'' (2nd century AD) described a point called Βορειον (''Boreion'', "the northern") which probably referred to Malin Head. Locality To the northeast Inistrahull Island can be seen. The first lighthouse on the island was put into operation in 1813, and the light flashes every 30 seco ...

Colonsay
Colonsay (; gd, Colbhasa; sco, Colonsay) is an island in the Inner Hebrides of Scotland, located north of Islay and south of Mull.

Aligned on a south-west to north-east axis, it measures in length and reaches at its widest point. Geology The Colonsay Group, which takes its name from the island, is an estimated sequence of mildly metamorphosed Neoproterozoic sedimentary rocks that also outcrop on the islands of Islay and Oronsay and the surrounding seabed. The sequence has been correlated with the Grampian Group, the oldest part of the Dalradian Supergroup. It includes the meta wackes of the Oronsay Greywacke Formation, the sandstones of the Dun Gallain Grit Formation, the metasandstones and metamudstones of the Machrins Arkose, Kilchattan and Milbuie formations, the sandstones and phyllites of the Kiloran Flags Formation and the phy ...
