Palynology of the Miocene Browncoal mined at Haanrade (Limburg, Netherlands)

The browncoal of the quarry “Anna” at Haanrade belongs to layer F, the middle one of the three layers into which the main browncoal deposit splits towards the NW. It correlates with the lower part of the German series, and in all likelihood is of middle miocene age. The coal is very rich in pollen grains, and the latter belong to a great diversity of species. Spores are less common. Of all pollen species the taxonomic position has been traced. The pollen diagram shows no striking fluctuations. It seems likely that a' moderately subtropical climate prevailed during the miocene.
