Patterns, processes and models – an analytical review of current ambiguous interpretations of the evidence for pre-Pleistocene glaciations

Autor: Molén Mats O.

Publikováno v: Geologos, Vol 29, Iss 3, Pp 139-166 (2023)

Models (paradigms) and former interpretations have often been presupposed when conducting field research. In the 19th century diamictites were for the first time interpreted to have originated from ancient glaciations. These interpretations have to a

Reconsidering the glaciogenic origin of Gondwana diamictites of the Dwyka Group, South Africa

Autor: Molén Mats O., Smit J. Johan

Publikováno v: Geologos, Vol 28, Iss 2, Pp 83-113 (2022)

The Gondwana Late Palaeozoic Ice Age is probably best represented by the Dwyka Group in South Africa. Striated and grooved surfaces or pavements are commonly considered to have formed subglacially, as are diamictites which have been interpreted as in

Field evidence suggests that the Palaeoproterozoic Gowganda Formation in Canada is non-glacial in origin

Autor: Molén Mats O.

Publikováno v: Geologos, Vol 27, Iss 2, Pp 73-91 (2021)

During more than a century since its original identification, the Gowganda Formation in Ontario (Canada) has gradually been reinterpreted from representing mainly subglacial tillites to secondary gravity flow and glaciomarine deposits. The main piece

The origin of upper Precambrian diamictites, northern Norway: a case study applicable to diamictites in general

Autor: Molén Mats O.

Publikováno v: Geologos, Vol 23, Iss 3, Pp 163-181 (2017)

Upper Precambrian diamictites in Varangerfjorden (northern Norway) have been examined for evidence of origin, whether glaciogenic, gravity flow or polygenetic. Studies of geomorphology, sedimentology and surface microtextures on quartz sand grains ar
