Borlasbach

The Borlasbach 150 m before the confluence with the White Ritz

The Borlasbach (formerly in the upper reaches of the Seifenbach ) is a left tributary of the Red Weißeritz in the Saxon Erzgebirge. It has its origin at the foot of Paul Heide at Paulshain, then it flows in a northerly direction passing through Borlas and Lübau where the waters orographic left opens into the Red Weißeritz.

The Borlasbach has a very asymmetric valley shape in the upper and middle reaches. The right side with its steep slopes is mostly wooded, the flatter left side is used, however, for agricultural purposes. In the lower reaches of Lübau to the mouth of the Red Weißeritz the brook close up to 40 meters deep gorge forms the left side of Rabenauer reason. In the upper reaches, there were several small ponds.

Noteworthy is the occurrence of placer gold in Borlasbach at Paulshain, which in basic gravels of Niederschöna lineup no longer visible paleosols under the cuboid sandstone deposits of Paul Strand and Höckendorfer heath is present and is flushed out with the water at the base of the sandstone layers in insignificant amounts. A gold mining by mining soap work is on record dating back to 1560, but occupied only once. Thus, the Borlasbach one of the few gold bearing waters in Saxony. A mining recovery was due to the small quantities but instead only briefly.
