摘要:

In a profile at Tingshuset, Drammen, Norway, a rather unique condition exists with respect to sensitivity and salt content of the clay deposit. The clay is originally deposited in sea water, and the salt has successively been leached out from beneath due to artesian overpressure. — At a certain time the entire profile is believed to have been quick. However, at the present time, this is not the case. Below the quick zone the sensitivity has been reduced to less than 20 even though the salt content is very low throughout the profile. This phenomenon is explained by in-situ production of magnesium and calsiuin ions probably due to aggressivity of the upward streaming fresh water attacking the more unstable minerals.

摘要:

A large glacial boulder of quartz-diorite found at the village of Långträsk contains closely packed orbicules characterized by dark core fragments surrounded by numerous light and dark shells. The composition of the shells is related essentially to the relative proportions of amphibole/biotite and andesine plagioclase.

摘要:

The Skallhult plateau is situated in an cast-westerly pass of Hökensås, a mountain ridge that separates the Vätter and Tida basins on the northern border of the South Swedish Highlands. The plateau has formerly been interpreted as an ice marginal delta built up in the Baltic Ice Lake (Munthe 1940) or in a local ice lake which covered the Vätter and Tida basins south of the ice margin (cf. Munthe 1910 and Nilsson 1939, 1953, 1968). These interpretations have been forwarded without any descriptions or proofs as regards morphology and stratification.

摘要:

In the iron ore claim of Grustagsgruvan at Vattholma, 20 km N of Uppsala the author has discovered an occurrence of subglacial limestone. It hat been deposited in sheltered cavities on one of the glacially-sculptured outcrops of iron ore. These outcrops were formerly covered by esker gravel. The subglacial limestone has the shape of oval concretions and knobs. They are often arranged in orientated rows and are formed by fine-grained sand and carbonate in about the same proportions. Several of the outcrops of iron ore are coated with gravel grains fixed to the substratum by carbonate. The concretions are interpreted as formed by erosion of a primary and partly diagenetisized filling of find-grained sand in the cavities. The carbonate is derived from the Cambro-Silurian or Archaean limestone material in the esker.

摘要:

Two localities with deposits of wind-blown silt — the first to be described from southern Sweden — have been examined by mapping and by hydrometer analyses. The silt is supposed to have originated from glacio-fluvial deposits and to be of late-glacial age.

摘要:

A new zone system is proposed based on various information in Southern Scandinavia about climatic changes during the Late Weichselian. These changes are supposed to have been controlled by global climatic changes.
