1. Palynostratigraphy and palaeoclimatic analysis of Lower-Middle Jurassic (Pliensbachian - Bathonian) of the Inner Hebrides, NW Scotland
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : A palynostratigraphic investigation of partly ammonite dated, Pliensbachian to Bathonian (Early – Middle Jurassic) strata on the Isles of Skye and Raasay, Inner Hebrides in Northwest Scotland, has recovered a diverse but not always well preserved miospore flora and a less diverse dinoflagellate cysts flora. The studied interval has been subdivided into five biozones, A - E, based on the first occurrence, common occurrence, first common occurrence, and relative abundance of pollen and spore key taxa.

2. Late Triassic and Early Jurassic palynology of the Höganäs Basin and the Ängelholm Trough, NW Scania, Sweden
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : A palynological study has been conducted on Late Triassic and Early Jurassic outcrop- and borehole sections of the Höganäs and Rya formations, NW Scania. The diverse and generally well preserved palynomorph assemblages can be divided into three miospore zones: (1) the latest Rhaetian-?Hettangian Transitional interval; (2) the Hettangian Pinuspollenites-Trachysporites Zone; and (3) the Sinemurian Cerebropollenites macroverrucosus Zone.

3. Upper Triassic depositional environments at Lunnom, northwest Scania
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : 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. LÄS MER
