Scawt Hill is a volcanic plug in County Antrim, Northern Ireland, in the borough of Larne, 5 km from the village of Ballygalley.〔(Habitas, Scawt Hill, Site Description )〕 It gets its name from the Ulster Scots '' 'scawd' '' meaning scaly, scabby or rugged.〔(Mountain Views, Walk Sallagh Braes to Glenarm )〕 Alternately, '' 'scawt' '' meaning scruffy and contemptible, and when applied to rocks, covered in barnacles.〔(Dictionary of the Scots Language )〕 ==Discovery of Minerals== Scawt Hill is notable for being the type locality for several hydrated calcium silicates,〔(Mineral and Locality Database, Scawt Hill )〕 that is, the place where they were first identified. These minerals were formed when the existing chalk of the area was intensely altered by the intrusion of the feeder tube of an ancient volcano, now long since cooled and eroded to its roots.〔Wilson, H E et al (1986) Geological Survey of Northern Ireland, HMSO〕 Minerals that were first discovered at Scawt Hill: * Larnite (''calcium orthosilicate'')〔 a natural form of Belite discovered in 1929〔(Mineral and Locality Database, Larnite )〕 and named after Larne, the nearest town * Scawtite in 1929 * Portlandite in 1933〔(Web Mineral, General Portlandite Information )〕 * Hydrocalumite in 1934 * Rankinite in 1942 * Bredigite in 1948〔 In all, 28 minerals have been found at this site.〔(Habitas, Scawt Hill, Summary )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Scawt Hill」の詳細全文を読む スポンサード リンク
