Mesozoic divergent boundaries formed the rhine rift, the Palatinate (Pfalz) winegrowing region is located inside the rhine rift east of the now fragmented edge that is divided into numerous clods.

Especially the area of the Southern Wine Route between Frankweiler and Schweigen consists of material from the Mesozoic, formations of the trias (Sandstone, shell limestone, late triassic grounds) and the jura era. In areas of tertiaric clods and its lime but especially in the area towards the Rhine river with its tertiaric and quaternary sands this soil diversity is not comparably common in such short distances.

A 3 km long section from the Geilweilerhof near Siebeldingen and Birkweiler has especially many changings in soil condition that are easy to recognize. The Huebelberg (Huebel hill) across from the Geilweilerhof consists of shell limestone, blue grey colored early jurassic clay ground is found west of Siebeldingen, the Rauhberg east of Burkweiler consists of late triassic sandstone shimmering violet red.

In the area of Gleishorbach sandstone and shell limestone grounds alternate multiple times.
