Dr Steinmann regards the middle and lower sub-divisions as equivalents of the ‘older’ lss of European Pleistocene deposits.

The upper subdivision is designated the yellow lss in contrast to the brown lss forming the middle layer.

Sand and lss (a fine earthy deposit) had accumulated above it to a thickness of seventy feet.

In effect, the type of Solutr is assigned to the newer (jngerer) lss deposits.

According to Penck and Brckner, therefore, the lss is of interglacial age.
