A boring for water supply at Björnstorp E of Lund was placed in the south-western faultline of the Archæan horst Romeleåsen; it penetrated 66 metres of Ceno. manian greensand at a depth between 61 and 127 metres. As far as concerns Sweden this greensand was not known before, except in two deep borings at Höllviken, the south-westernmost corner of the province of Scania, were it was pierced ten years ago at a depth of 1 200 metres. The greensand contained ostracods, foraminifers, and macroscopic shell fragments, pebbles of sedimentary rocks, a piece of asphalt and probably traces of other bituminous products.
