Study aqueous alteration of CV3 chondrites and Martian meteorites

Ildiko Gyollai

As a geologist I study shock and thermal metamorphism of ordinary and carbonaceous chondrites by mineral spectroscopical methods for 7 years. Currently, I am occupied as young researcher in HAS-Center of Astronomy and Geology in Budapest, Hungary.

Between 1st -7th February 2015, under the STSM-TD1308-010215-053644-53644, with title “Martian meteorite analysis for astrobiology” I visited Dr. Elias Chatzitheodoridis's laboratories at the National Technical University of Athens. I made Raman spectroscopy and back-scattered electron microscopy measurements on Martian meteorites.

Currently I study aqueous alteration of CV3 chondrites and Martian meteorites. In this study made by this STSM I examine four nakhlite samples from similar Martian source area with new instruments,  to distinguish secondary minerals of terrestrial origin from Martian origin, proposing of formation circumstances of secondary minerals obtaining characterization of temperature, pH, and salinity of hydrothermal systems on Mars, to reconstruct conditions of hydrous environments.

After the STSM, the borrowed samples were examined in my home  institution, which could obtain help in calibration and evaluation our instrumental background to make compatible results with those gained in Athens.

Short Term Scientific Missions (STSMs)

Aiming at fostering collaboration, sharing new techniques, and infrastructure that may not be available in other participants' institutions or laboratories. STSMs are intended especially for young PhD researchers, but they are open to senior researchers as well. View the documents at this link.

 It should be explicitely noted that Master students are not eligible for STSMs which are for PhD students and more experienced researchers.

The life-Origins COST Project

Life-ORIGINS (TD1308) is a Trans Domain European COST Action dedicated to the scientific investigation of the origins and evolution of life on Earth and habitability of other planets.

The Action has specifically excluded the search for intelligent extraterrestrial life in its portfolio. Creationist theorems are also outside the Action’s remit.

Individuals are not allowed to use the name of the Action, its logo or any corporate identity of COST TD1308 in any communication without prior approval of the Management Committee.

All publications referencing the support of the Action should be sent to the appropriate Working Group chair at the time of submission.
