Palynological research of the "stump horizon" in the Bílina opencast mine (Most Basin, Miocene, Czech Republic)
Abstract
The Bílina opencast mine represents a unique locality in the north Bohemian Most Basin (Miocene), sometimes denoted as "a window on Early Miocene marshland environments". The main coal seam is overlain by the so called "stump horizon" (composed predominantly of grey-collored clays containing in situ preserved fossil trunks) from which three samples were processed for micropalaeobotanical evaluation. Palynological analyse of these samples, as compiled in the table, shows, that the formation of the "stump horizon" (trees did not survive permanent flooding) was caused by a rise of ground water level.
