A4: TURKEY CURUK DAG SITE

This page authored by Steve Kershaw


Curuk Dag is probably the best site in the world to show the diversity of microbialite forms in the PTB sequences. The site was made internationally important by Baud et al. (2005), location map and photo below.

In the log note:

stromatolites (blue), thrombolites (yellow) and laminated sediments that contain bioclastic and micrite layers, together with hybrid microbialites (orange).


Red lines are either bedding planes or stylolites, or bedding planes modified by stylolites; microbialites may be composed of several layers with minor breaks, but stylolites cause confusion about exact nature of such lines.


The microbialite sequence shows repetitions of units, and may be interpreted as caused by sea-level changes. A model of deepening-up units can explain the sequence.
