H.P. Geis (1967): I følge opplysninger fra NGU skal forekomsten ligge mellom Langtjern og Bråtan, syd for Aspersjøen i Aremark kommune. Forekomsten ligger nesten ved svenskegrensen, ca. 30 km i luftlinje fra kysten. Den er derfor neppe av interesse.

Abstract:

Oppramsing av hele landets jern-titanforekomster, hvorav 15 trekkes fram som de største. Hver forekomst beskrives ut fra befaring med geologiske og dels kjemiske data. Oppredningsresultater presenteres også. Oppramsing- en går fra Hedmark til Finnmark i nord.

Abstract:

On the map accompanying this paper all the mines and ore deposits of Southern Norway are collected for the first time.The material has been gathered from printed and unprinted sources, communications from mining engineers and geologists, and through personal visits. Included are all mines and ore deposits of former, present and future importance. Among the 1407 deposits on the map, there are furthermore included all of doubtful value and many which are quite unworkable, but of geological interest, or those which mark the distribution of ore bearing formations. For this reason it has been necessary to mark the deposits with signs of different size. The object is only to facilitate a comprehensive view of the map, and is not an effort of economic classification, which for most of them would be quite impossible. The sizes refer to the presumed importance of the ore deposit, and has nothing to do with the extent of the mining operations. Mines and deposits out of work during the period 1913-1923 have been separately marked (see the legend), also deposits which were formerly of much greater importance than now. For the smallest mines and deposits no distinction has been made in these respects. Among them are represented partly those, which are in reality unworkable, partly those which are little investigated.
