    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Line Larby; Annie Lundberg; [2018]
    Keywords : ;

    Abstract : Vanadium can be found in some iron ores as an impurity. Since vanadium is a valuable alloy element there lies an interest in development of a stable and economic way for extraction of it. For this, knowledge about the thermodynamics behind the V-O system combined with other elements, like Mg, is indispensable. READ MORE

  4. 3. The life cycle and developmental phases of Cambrian-Ordovician organic-walled microfossils from Kolguev Island, Arctic Russia.

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Magdalena Pazio; [2016]
    Keywords : Saharidia fragilis; Prasinophyceae algae; life cycle; acritarchs; Saharidia fragilis; Prasinophyceae; livscykel; acritarch;

    Abstract : Light microscopy studies of collections of late Cambrian/Early Ordovician organic-walled microfossils, informally called acritarchs, provide the observations on phenotypic traits that are comparable to Modern microalgae and make possible recognition of various developmental stages in their complex life cycle. The exceptionally preserved Saharidia fragilis microfossils show the internal body within the vesicle and the formation of the fringe and pylome, the opening for releasing of the daughter cells from the phycoma-like cyst.

  5. 4. Late Triassic and Early Jurassic palynology of the Höganäs Basin and the Ängelholm Trough, NW Scania, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Keywords : Transitional interval; Pinuspollenites-Trachysporites Zone; Scania; Rhaetian; Palynology; Hettangian; Cerebropollenites macroverrucosus Zone; Helsingborg Member; Döshult Member; Earth and Environmental Sciences;

    Abstract : 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.
