CONTRIBUTIONS TO THE MINERALOGY OF NORWAY No. l. An Introduction.

BY HENRICH NEUMA��

Apart from more voluminous monographs the literature on the mineralogy of a certain area tends to consist of a great number of short papers and even of mere notes putting on record finds of a rare mineral or of a certain mineral in an interesting or unusual environ­ ment. As far as Norway is concerned such small papers and notes have also in part been published in journals which are not too widely circulated and read, and they are therefore easily overlooked even by Scandinavian mineralogists, not to mention the international group of interested readers. This new series "Contributions to the Mineralogy of Norway" is introduced as an attempt to make the future literature on Norwegian

mineralogy more conveniently available and more easily reviewed. The "Contributions" are not intended to be the "house bulletin" of any one institution nor a convenient tool for any one group of coo­ perating scientists, on the contrary any mineralogist working within the field concerned, Norwegian or otherwise, is urged to submit his papers for publication in this series, thereby helping it to serve its purpose. In 1948 I. Oftedal published a review of minerals found in Norway up to that time (Oversikt over Norges mineraler. Norges Geologiske Undersøkelse No. 170 (1948)) with short comments on their mode of occurrence. It would seem appropriate in an introduction to the "Contributions" to adO. to Oftedal's list of minerals a few species

which were overlooked at the time, and also to list those species which have been found in this country since 1948: Allophane from a vein through lower Ordovician black shale in Oslo. (30) .1 Ancylite from Langesundsfjord. (G.M.)2 Anglesite from Kvaløy, as an alteration product of galena. (Found by T. Sverdrup). Annabergite from Råna nickel deposit as an alteration product of niccolite. (G.M.) Bastniisite see the following paper of this journal. Bavenite from a pegmatite dyke at Boksjøen near Aspedammen in the county of Østfold as a younger reaction product of beryl. (G.M.) (Found by O. J. Adamson). Birnessite from supergene infillings of manganese minerals in fissures in nordmarkite at Lillevann near Oslo. Birnessite may not be a valid species. (G.M.) Brannerite in open fissures in green schist near Åmot in Modum and probably genetically related to granitic pegmatite dykes near by. (4) Brookite from a pegmatite dyke on Straumsheia. (24). Cahnite from Klodeborg mine at Arendal (7). Carrolite from Borras copper deposit at Alta in the county of Finnmark. (53). Clzamosite from Kongsberg, Norway.3 Clausthalite from Kongsberg and Nummedal. (13). Cookeite from a pegmatite dyke at Holanclsfjord, N. Norway. (G.:\l.) Davidite from the Tuftan pegmatite clyke, Iveland, Setesdal. (G.:\I.) Epsomite from Storhelleren, Fauske in the county of Nordland. (G.:\I.) Euclase from Iveland as an alteration procluct of beryl. (50). Gahnite from Tor's mine, Øvre Vats in a pegmatite dyke.4 (Founcl by H. Ramberg). 1

from a chromite deposit near Røros, and from Kalkovnen, Grua near Oslo. Yttrialite from the Ivedal pegmatite dyke in Iveland, Setesdal. (G.:VI.) The following species described from �orway have been discarded since 1948: Apoanalcite (31) Ranite ( = gonnardite) (19) Weibyeite (G.l\1.) In the paper mentioned above I. Oftedal gives a list of literature references with 136 entries on Norwegian minerals and mineral deposits. The list is not by any means complete but together with literature referred to in the papers listed by Oftedal it will cover the field fairly well. Below follows a list of Norwegian mineralogical publications printed since 1948. Uvarovite
