Abstract
This paper is the result of observations made of the Later Triassic-Jurassic tectonic movements in Skåne. The gentle structural movements during Upper Triassic deposition occurred against the background of the orogenic events of the Variscian Era. These relations may be visualized from the accompanying section (Fig. 1). The origin of the saxonic structures is examined from the viewpoint of the interplay of two factors: (1) a regional and long-lasting en bloc uplift of the Baltic Shield, accompanied by (2) the successive displacement of fault-blocks — differential movements, in which periods of denudation or sedimentation alternated. The Upper Triassic in Skåne was a period of crustal quiescence; the tectonic movements were of an epeirogenic nature. These movements were the forerunners of orogenic disturbances in the Upper Jurassic, but already in the basal Liassic, at the base of the Fleninge sandstone, angular unconformities and other indications of orogenic disturbances occur (Figs. 2 and 3). The cumulative evidence for a true orogenic phase in the Upper Jurassic is overwhelming, and many of the present structural features in Skåne were probably produced already in this early phase of the saxonic movements. Some questions of practical interest, connected with these tectonic events are discussed.
