Dr Yves Godderis said that the formation of these mountains meant that the rock weathering, which was threatening to slow to a walk through much of the supercontinent, was able to continue and the steep slopes of these Hercynian Mountains produced physical erosion occurring in a humid equatorial environment, this physical erosion promoted rock weathering and removing CO2 from the atmosphere.

The Harz Mountains as a whole are characterized by very complex geology, with diverse rock types forming an intricate patchwork (see map) representing the eroded roots of what were once mountains formed by the Hercynian (also called the Variscan) Orogeny that took place during the Carboniferous period some 350-300 million years ago.
These movements were most probably created by the Caledonian and Hercynian orogenies which caused major structural deformation during the Palaeozoic in SE Turkey and the Arabian Plate [20, 21].
