摘要:

The author has visited the part of the large glacier Svartisen in Norway that is called Österdalsisen (Fig. 1) in the years 1935 and 1960. An immense wastage during this interval has been established as illustrated by photographs. In front of the western tongue an ice-dammed lake was formed which in 1943 was partly drained towards the east below the ice. In 1959 this draining was made artificial by means of a tunnel in the bedrock. The ice-dammed lake was filled with large ice boulders and it is therefore like the formation milieu of the ablation moraine. The author recommends a continued study of the area. Some mention is given of the insignificant normal deposits (till and sand) of the glacier.

摘要:

Fabric data (chieflys-surfaces and lineations) have been collected in twelve areas along a 200 km long NE—SW line in the northern Caledonides of Scandinavia. The bedrock consists of overthrust laminated rocks tending to be sub-horizontal S-tectonites. In 241 instances, lineations striking about NW—WNW have been deformed by small folds of other strikes. This is part of the evidence for postulating different phases of deformation. The main lineation maximum for the areas strikes WNW. Lineations with this strike are strongly correlated with local β-maxima with the same strike. However, the main β maximum for the areas strikes NW. Movement directions are discussed,i.a.on the evidence of 720 instances of small overturned folds. Boudinage shows a preferred orientation that is not obviously correlated with either the strongest lineation maximum or the strongest maximum for β. Joints are as a rule not obviously correlated with other fabric elements and appear to have been formed after folding had ceased almost entirely.

摘要:

A brief description is given of a boring through the Tretaspis series and the uppermost portion of the Chasmops series in the Fågelsång district. The examined portions of the Chasmops series agree with the corresponding strata in Bornholm. The Tretaspis strata which hitherto had been almost unknown in the area consist mainly of pale mudstones and shales including black graptolitiferous layers. They exhibit remarkable similarities with the Moffat series in Scotland and the sequence from Brzezinki in Poland. The following subdivisions are distinguished (from below upwards): 1) Zone ofTretaspis granulata;2) Zone ofDicellograptus anceps;3) Practically unfossiliferous mudstones for which the termLindegård mudstoneis proposed.

摘要:

The cave at Lummelunda, Gotland, is developed along an underground stream in Silurian reef limestone. The mouth of the cave is situated in a scarp near the present coast line, above the Litorina strandline. The cavern system, consisting of open rooms and narrow channels, is known to an extent of more than 150 m from the mouth (Fig. 1).
