摘要:

Uranium indications in the Tåsjö Lake area, Västernorrland County, discovered in 1957 by the Swedish Atomic Energy Company, have been the subject of comprehensive geological studies by this company from 1960 through 1965.

摘要:

A film on which the dispersed particles are printed as dark sections on a light background is searched according to the flying-spot-principle, which generates a screen of lines. For each line the brightness is measured by a known quantity of equidistant points. With the assistance of a computer, the measured values of the brightness at each point are-investigated line after line. All points on a line which belong to one and the same particle are combined into a line section. A special procedure has been developed for matching all line sections in a particle. This procedure makes it possible to deal with double entrances, i. e. prongs and parts projecting from the main body, particles in the shape of a ring and particles situated inside a ring. After this sorting, the specific calculations of data for all particles are carried out and recorded, for instance, seeking out the main axis, the centre of the projected surface, the length and the width, the surface and many other things of interest.

摘要:

The position of the highest shore-line on Jakobsdalsberget in Kolmården has been determined. The shore-line was formed by the Baltic ice-lake about 8500 years B.C. The investigation shows that clear indications of wave-washing are found up to about 154 m above sea-level.

摘要:

A short description is given of Lower Turonian (Cretaceous) ammonites from Colombia and Trinidad. The agreement already established for the Lower Turonian of these two regions is further strengthened by the finds recorded here. The ranges ofHoplitoides wohltmanni(von Koenen),Neoplychites telingaeformisSolger, andN. crassusSolger can now be extended from West Africa to Trinidad and Colombia, andKamerunoceras eschi(Solger) from West Africa to Trinidad. The age of the assemblages is undoubtedly Lower Turonian and, more specifically, the upper part thereof. The collections also containCoilopoceras, MammitesandBenueites.

摘要:

Aspects of Gösta Armands's paper A uranium-bearing layer from the Lower Ordovician, Sweden” are discussed. The stratigraphical context of the Tåsjö uraniferous unit is reviewed and a tentative model för its depositional environment is proposed.
