Hydrothermal system in late Archaean - its impact on an abiotic environment composition

Recruitment begins on March 6, 2020 and ends on April 15, 2020.
Recruitment begins on January 1, 2020 nd ends on February 3, 2020.

Place of employment: ING PAN Research Center in Warsaw, ul. Twarda 51/55;

We offer interesting research work in the project: “Hydrothermal system in late Archaean - its impact on an abiotic environment composition." (NCN project - implementation time three years, one full-time position for doctoral student).

Life most likely appeared on Earth at the stage of its early evolution. It was favored by the strong greenhouse effect and higher surface temperature of the Earth, which could stimulate the development of thermophilic organisms. Perhaps these conditions persisted until the initiation of an intense exchange between the earth's mantle and the crust, which could result in sequestration of carbon dioxide through the mantle. Intensive exchange was associated with the formation of igneous melts; as a result of the magmatic evolution also hydrothermal systems appeared and evolved. Even if the Earth's surface at the end of the Archaean (2.5 billion years ago) was significantly cooled, hydrothermal systems could still support conditions conducive to the development of life. The question arises how the hydrothermal system worked at the end of the archaic. Was it similar to later, younger, or its characteristics were completely separate. In order to get answers to such questions, a plutonic, granite massif from the Indian Dharwar craton, 2.5 billion years old, was selected. This massif has numerous changes resulting from the impact of hot and very hot solutions of a mantle or a crust-mantle origin. The duration of action of these solutions is not dated. The project envisages the reconstruction of the composition of these solutions on the basis of studies on the chemical composition of minerals, the composition of their domains formed as a result of igneous and hydrothermal crystallization, and the dating of hydrothermal domains.

The research will be based on cooperation with research centers in Poland and international cooperation. The research team appointed to implement the project has many recognized research results in the field of early Earth evolution, including research on the composition of minerals and solutions (fluid inclusions) from granitoid massifs, experimental studies of the mineral - solution reaction, dating of minerals.

REQUIREMENTS:

We are looking for candidates who meet the following requirements:

1) have a master's degree *;

2) knowledge of the formation and transformation of minerals in hydrothermal solutions, especially in the geochemical aspect;

3) have good or at least basic knowledge of EPMA, LA ICP MS, HR TEM, CL methods;

4) are fluent in English;

 (*) Candidates who do not have a second degree diploma at the time of application must submit a letter from the parent unit stating that the studies will be completed in 2020.

In the title of the message please indicate "Archaiczny_Hydrotermalny_System".

If necessary, please send any queries (not applications) to Prof. Ewa Słaby to the address e.slaby@twarda.pan.pl

Additional provisions are possible depending on successful research grants applications.

The supervisor will be Prof. Dr hab. Ewa Słaby, e.slaby@twarda.pan.pl, Institute of Geological Sciences PAS.
