Upper Triassic depositional environments at Lunnom, northwest Scania
The mid-Rhaetic sequence at Lunnom, with coal and kaolinitic clays, indicates partly deltaic environments affected by alluvial processes during humid conditions. Of special interest is a thin bed of sandstone with coarse, angular quartz grains. The bed occurs mainly as a covering sheet on top of a heterolithic sequence in the eastern parts of the pit, while it is recognized as isolated dunes insid
