| Dette skjerpet befinner seg oppe i lia ca. 125 m over tunnel på Hatlestandvegen. Det består av en 15 m lang stoll med 7-8 m skjæring parallell strøket i grønnskifer som er vertbergarten. Stollen skal ha vært drevet av det engelske selskapet som hadde Valaheien gruver og er således sannsynligvis fra 1860-eller 70-årene. Foliasjonen er 030/75 grader i skiferen. Innerst i stollen er det en ca. 70 cm sone med pyrittimpregnert klorittskifer. Prøver på tipphaugen som for øvrig er temmelig overgrodd består av striper mm-cm mektige med svært finkornet pyritt i klorittskifer. |

| Abstract: | |
| When Steinar Foslie suddenly passed away in november 1951, he had finished the geological map here presented: "Kisdistriktet Varaldsøy-Ølve i Hardanger", based on field-work during 1942-49. Furthermore his M.S. contained a thorough petrological description of the rocks (p. 1f.) and the history of the copper-mining in the Ølve-district "Christiansgaves (Lilledale) kobberverk" from the two periods 1642-73 and 1759-85, holding a lot of items based on the study of records (p. 55 f.). These M.S. are printed unaltered, introduced by the author's own preface. The paper as a whole must be looked on as a basic draft only: An obviously planned section treating the ore deposits and their mineralogy has not been worked out, yet the facts presented may throw light upon general problems connected with the pyrite-deposits of Norway. As appears from the map the predominant rock in the pyrite-district is greenstone, more or less schistose. The term "greenstone" is here used for basic lavas and tuffs only, while the designation "the greenstone formation" is used by Foslie in the same sense as for the widely extended pyrite-bearing group in the Trondheim-district. |
