Geochemistry and Isotope Geology

Leander Kallas

Current Position

Curator of the GEOROC Database within the DIGIS project (Digital Geochemistry Infrastructure for GEOROC 2.0) in the department of Geochemistry and Isotope Geology, Georg-August-University Göttingen.
Responsibilities include data harvesting from the geochemical literature, data entry into an SQL database, development and testing of standardised data entry & anaylsis tools as well as the new web interface for GEOROC 2.0.

Research Interests


  • High-temperature geochemistry and isotope geochemistry, petrology, mineralogy, cosmochemistry

  • Geochemistry and evolution of volcanic systems

  • Geochemical evolution of the crust-mantle systems of the early Earth

  • Tools: major and trace element geochemistry, stable and radiogenic isotope geochemistry
