Professor's corner

Jochen Kolb, research professor at GEUS since 2011, holds a PhD from RWTH Aachen University, Germany. He applies an integral approach to describing crustal fluid systems. With a special aim of describing different mineral systems, Jochen Kolb is interested in combining structural geology and petrology to study the interface between the various processes related to the formation of mountains.

In 2014 Jochen Kolb has joined the Geochemical, Mineralogical and Petrological Earth Processes research group as adjunct professor. With his adjunct professorship Jochen Kolb hopes to secure research in economic geology in his fields of interest and economic geology education in general at the University of Copenhagen and within the Geocenter Denmark.

Jochen Kolb has a special interest in disseminating his own interest in geology to students and has contributed to the completion of many master, ph.d. and post.doc thesises (see below). You are welcome to contact Jochen with inquiries regarding collaboration on projects. 

Research fields

Processes in the lower Archaean and Palaeoproterozoic crust: gold and nickel systems

Deep structure of early orogens: Archaean and Palaeoproterozoic tectonics

Hypozonal orogenic gold deposits: the deep expression of hydrothermal activity

Deep ductile shear zones: how is permeability generated and fluid focused

Direct borax smelting as an alternative for amalgamation of gold ores in small-scale gold mining
 
Various economic geology projects in Greenland (graphite deposits, Fe-oxide-Cu-Au deposits)
 
Applied projects directed towards the development of exploration strategies for sustainable mining
