Organic matter studies of Permian – Triassic sediments in the Caucasus of Armenia

Background:

Permian and Triassic sections in the Pre-Caucasus in Armenia are developed in siliciclastic facies of the Northern margin of the Tethys ocean. Some of these outcrops belong to the best sections for studying the evolution of Late Palaeozoic and Mesozoic Mesozoic biota, in particular during the End-Permian and the Late Triassic environmental changes and related mass extinctions.


Aims:

The aim of this study is: 1) to reconstruct the sedimentary environment based on organic facies analysis and 2) establish a record of pollen & spores and marine algae remain (acritarchs and dinoflagellate cysts) for a biostratigraphic subdivision and correlation.

Eventually, also methods from sedimentology and organic geochemistry (for example rock eval) can be included in the project.

 

Research methodologies:

  • Extraction of sedimentary organic matter from rock samples.
  • Microscopic analysis of particulate organic matter palynomorphs (pollen, spores, algae remains)
  • Statistical analysis of data and correlation with regional studies
