Der quartäre Osteifel—Vulkanismus im Rahmen der Lößbildung—ein Beitrag zur Lößgenese

Wolfgang Tillmanns & Hans Windheuser
An intensive volcanic activity takes place in the precisely defined Laacher volcanic area since the Middle Pleistocene. It can be shown through the heavy mineral and grain size analyses that the volcanic region is a considerably important local source area for the formation of loess. The proportion of the volcanic heavy minerals proves the dominant significance of reworking processes for the loess genesis in the Laacher volcanic area. The content of the volcanic heavy minerals...
