Zagros Gebirge, Iran (z Z nicht angeboten)

15-day field trip
Total costs: about 500 € including all boards and transfer/lodging. Subject to changes in the exchange rate of the Iranian currency (Rial).

This field trip focuses on
a) the largest mass extinction event in shallow marine environments at the Paleozoic-Mesozoic boundary (Permian-Triassic Boundary);
b) genesis and exploration of oil and gas, their source rocks (lower Cretaceous to Early Tertiary shales and marls) reservoir rocks (upper Cretaceous to early Tertiary carbonates), and cap rocks (evaporites);
c) genesis and tectonic of salt domes and diapirs; and
d) transport and deposition mechanisms in eolian system, formation and types of sand dunes and sandstones, ripple marks, evaporative crusts, etc.

Program:

The field trip will start with the THY-flight Bremen-Istanbul-Isfahan (1 day), followed by 6 days in central Iran and 7 days in south Iran, and ends with the return flight Shiraz-Istanbul-Bremen (1 day).

The students will gain knowledge on petroleum geology, formation and exploration of oil and gas, carbonate rocks, their classification and factors controlling their porosity/permeability, formation and tectonic of salt domes and salt diapirs, Alpine orogeny and the associated tectonic processes in the Zagros Mountains, inner and outer ophiolites and their composition, transport and deposition mechanisms in eolian systems, and mass extinction events in Earth history.

Writing a report for particular days of the field trip, will be assigned at the end of the field trip.
