Determination of a normal palaeo--geothermal gradient comparing the reaction progress of clay minerals calibrated with organic maturity indices Dedicated to the 90 th birthday of Hans Krumm

Résumé

Based on the large data set of the authors from different orogenic belts, geodynamic setting with a normal geothermal gradient were selected. In these studies clay mineral versus organic matter correlations show in the vitrinite reflectance (VR)/Kübler Indices (KI) plot from Ferreiro Mählmann et al. (2012) gradients with "moderate (normal) geotherm" conditions. Using maturity modelling and clay mineral reaction progress studies a normal temperature gradient of 25 to 35 °C was estimated.
