Volcanic host rocks have hydrothermally been altered and can be divided into four parts vertically: kaolinization, chloritization, epidotization, and silicification.
The inferred paragenetic sequence of the studied sandstone include both physical and chemical compaction, dissolution of feldspars and kaolinitization, chloritization and illitization ofsmectite, quartz overgrowth, calcite cementation and dolomitization, uplifting and deformational bands formation, and iron oxide/hydroxide cementation and its partial dissolution.
In the depocentre of the basin, a low-grade metamorphic event (hydrothermalism) took place, leading to some mineralogical changes in the original petrofacies, including silicification, chloritization and the albitization of feldspars.
The appearance of a similar phenomenon as an evident relict in the Dividal Group rocks of Lapland is remarkable, because during the local post-diagenetic deep changes (sericitization and chloritization of sedimentary rocks), the reduction, which is probably caused not by organic matter, but by other reductive fluids, encompasses the entire rock massive.
Clearly, hydrothermal breccias, related pervasive alteration and mineralization (silicification, chloritization, and greisenization) in GRI and GRII (Kooiman et al.
The Lasenice granite was described as an independent early-stage intrusion in the Moldanubian batholith, because it shows an intensive tectonic deformation, partly connected with a chloritization (Klecka and Rajlich 1984).
Laterally extensive sericitization and chloritization affect the Contact Unit's basal footwall breccia.
