Multistage dolomitization of upper jurassic mozduran formation, Kopet-Dagh Basin, n.e. Iran [PDF]

Carbonates and Evaporites, 2009
This paper is a study of the origin and diagenetic history of the Upper Jurassic dolomites of the Mozduran Formation, from north eastern Iran, in the Kopet-Dagh Basin. Petrographic and geochemical studies indicate that the Mozduran dolomites were subjected to a complex diagenetic history, resulting five different dolomite—rock textures. Dolomite type 1

The Atlas of Morocco: A Plume‐Assisted Orogeny

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 6, June 2023., 2023
Abstract We explore the connections between crustal shortening, volcanism, and mantle dynamics in the Atlas of Morocco. In response to compressional forces and strain localization, this intraplate orogen has evolved far from convergent plate margins.

Hotspots of (sub)alpine plants in the Irano‐Anatolian global biodiversity hotspot are insufficiently protected

Diversity and Distributions, Volume 29, Issue 2, Page 244-253, February 2023., 2023
Abstract Aim The mountainous regions in SW Asia harbour a high number of endemic species, many of which are restricted to the high‐elevation zone. The (sub)alpine habitats of the region are under particular threat due to global change, but their biodiversity hotspots and conservation status have not been investigated so far.
