Introduction
Hjelmeland is a municipality in Rogaland county, located in the traditional district of Ryfylke. It is one of the larger municipalities in Rogaland, though sparsely populated. Established in 1838, Hjelmeland has undergone several boundary changes, historically linked to local governance reforms. The name derives from Old Norse Hjalmaland, meaning “helmet land,” possibly referring to the shape of local mountains. [en.wikipedia.org], [snl.no]
Geological Framework
The bedrock consists mainly of Precambrian gneisses, strongly metamorphosed during the Caledonian orogeny, with overlying Cambro-Silurian schists in some areas. The municipality includes fjord landscapes such as Jøsenfjorden and Årdalsfjorden, flanked by steep mountains and high plateaus reaching 900–1,200 m. Glacial erosion during the Pleistocene sculpted the fjords and left extensive moraines and meltwater deposits. A unique geological feature is the Ritland impact crater, a 2.7 km-wide structure formed by a meteorite impact about 500 million years ago. The crater was later buried under Caledonian nappes and re-exposed by erosion, revealing brecciated rocks, suevite, and fossil-rich sediments. Riis et al.(2011), [ngu.no],[fjordnorway.com]
Mines and mineral localities
With the exception slate production for roofing and building minerals in the 19th and early 20th centuries, there are no noteworthy mining history or mineral localities in Hjelmeland.
