Saargemünd-Zweibrücker Triasmulde

The Saargemünd-Zweibrücker Triasmulde is part of the large geological Saar-Nahe depression , a sedimentation basin .

This initially geologically submerged area was filled with sediments over the course of millions of years during repeated lifting and sinking processes . The red sandstone found in this area is interpreted as a deposit of sand in a desert climate . A sea that periodically flooded the area from the southeast led to the deposition of layers of shell limestone . Then there are continental layers of the Keuper .

At the beginning of the Triassic , the previously flat area due to sedimentation was raised by 500 meters with a gradient from north to south-west. At the beginning of the Pleistocene 2 million years ago, numerous streams began to cut into this sloping area, which unite in Blies and Mandelbach . The receding erosion formed today's strongly structured, even fragmented, landscape.
