Arctic Bay Formation, Borden Basin, Nunavut (Canada): basin evolution, black shale, and dissolved metal systematics in the Mesoproterozoic ocean
(2012)The Arctic Bay Formation (Nunavut, Canada) represents a late Mesoproterozoic muddy terrigenous ramp and contains >200 m of black shale. The formation was studied in order to decipher the tectonostratigraphic and geochemical ... -
Inhibition of Calcite Growth: Combined Effects of Mg2+ and SO42–
(2016)Magnesium and sulfate are each known to affect calcite growth and dissolution, but little is known about their combined effects on calcite growth rates. We grew calcite using the constant composition approach at ambient ... -
Lake Ohrid?s tephrochronological dataset reveals 1.36?Ma of Mediterranean explosive volcanic activity
(2021)Tephrochronology relies on the availability of the stratigraphical, geochemical and geochronological datasets of volcanic deposits, three preconditions which are both often only fragmentary accessible. This study presents ... -
Petrology and dating of the Permian lamprophyres from the Malá Fatra Mts. (Western Carpathians, Slovakia)
(2018)Calc-alkaline lamprophyres are known from several localities in the Malá Fatra Mountains. They form dykes (0.5-3 m) of varying degree of alteration that have intruded the surrounding granitoid rocks which are often ... -
Reaction pathways and textural aspects of the replacement of anhydrite by calcite at 25 °C
(2017)The replacement of sulfate minerals by calcium carbonate polymorphs (carbonation) has important implications in various geological processes occurring in Earth surface environments. In this paper we report the results of ...
