Einige Bemerkungen über die Pollenführung der Braunkohlengrube “Maria Theresia”, Herzogenrath

The pollenflora of the browncoal mined in the quarry “Maria Theresia”, Herzogenrath, Western Germany has been investigated. Samples were taken along a section of 12.50 meters at intervals of 50 centimeters. Identifications were made on the basis of form-genera and form-species; this working method gives a broad information on pollen types, but does not relate the fossil pollen types primarily to recent plant taxa. Pollen types which are considered to belong to Betulaceae/Myricaceae make up the biggest part of the pollen assemblages. The construction of a “Composite diagram” for Betulaceae/Myricaceae proved to be useful and might give a better idea on paleoecologic conditions. The stratigraphic position of the browncoal examined is thought to be Lower “Hauptflbz”, possibly Morken or Frimmersdorf Horizont.
