FROM APPLIED FIELD AND LABORATORY GEOLOGY TO PLANETARY SCIENCE - AND BACK.

Introduction: Several well known connections exist between Earth and planerary sciences [1-10]. Such
interdisciplinary relations are aimed to exploit at the
MTA CSFK (RCAES) in Hungary as a recently formed
joint instiute. This abstract is to present those fields
where the work has started (for specific details see
cited references) and are prespectivitc using such synergy with the available facilites and background knowledge. The common issue of these topics is their analog
aspect what covers wide range of activites (from remote sensing, across field work to micro scale laboratory analysis). Tthe new issue is that fresh knowledge
and experience from planetary science might improve
and provide feedback to classical Earth sciences too.
Main topics of analog research where planetar
science related knowledge helps Earth sciences can be
seen in the Table 1. Several example exist where mission related information supported our knowledge in
geology (surface modification from ephemeral flow
events, low temperature alteration processes, handling
of small specimen with minimizing the contamination).
Specific interactions: The development and improvement during the analog activities improve mission
related technology. Hyperspectral band shape positions
got more accurate by standard production for planetary
missions, in the mineral scale infrared analysis improved the understanding on how elemental substitution distorts crystalline structures in meteorite minerals,
temperature, and compositional constrains of isotopic
exchange also got improvement from laboratory analysis to understand processes in meteorites and hydrothermal fluids on Mars. In these cases “reverse” spin-
off applications in modern geologic field and laboratory activites can be seen.
Figure 1. Ideal workflow that starts from geological field
work, though laboratory and related technology development supports Mars surface activity – the later improves
Earth geological methods
