Varves accumulating below the chemocline of meromictic Crawford Lake, Milton, Ontario, Canada, consist dark-colored organic matter laminations that are primarily deposited during fall plankton die-off, alternating with light-colored comprising calcite crystals precipitated a relatively narrow water temperature and pH-controlled depositional window in summer. A novel high-resolution imaging prot...

Abstract Two new records from the Amersfoort glacial basin are investigated by means of pollen analysis. The cores situated in deeper part, close to original Eemian stratotype 1 (Zagwijn, 1961) and at margin basin. aim is reconstruct Early Weichselian vegetation development explore impact accommodation space, influx allochthonous geomorphology on composition. results Basin compared current Amst...

51 samples from the Middle Triassic black shales (organic carbon−rich silt− stones; up to 4.9% TOC – Total Organic Carbon) from the stratotype section of the Bravaisberget Formation (western Spitsbergen) were analyzed with respect to isotopic composition of pyritic sulphur ( 34S) and TOC. Isotopic composition of syngenetic py− rite−bound sulphur shows wide ( 34S from −26‰ to +8‰ VCDT) and narro...

The Global Stratotype Section and Point for the newly defined Ediacaran System has been ratified at the base of the cap carbonate in Enorama Creek. A near-continuous section from the Marinoan glaciation to the base of the Cambrian is exposed in the Flinders Ranges, with type sections of included stratigraphic units exposed in the area around Brachina and Bunyeroo gorges. The stratigraphy and lo...
