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 “Hauptflöz”, possibly Morken or Frimmersdorf Horizont.
