Subduction tectonic erosion and Late Cretaceous subsidence along the northern Austroalpine margin (Eastern Alps, Austria)

The Late Cretaceous to Early Tertiary subsidence history of the Northern Calcareous Alps (NCA) records the effect of two independent basin formation mechanisms at the northern leading margin of the Austroalpine unit. The terrestrial to shallow-marine sediments of the Lower Gosau Subgroup were deposited mainly within small, fault-bound basins during a phase of strike-slip faulting from the late ...

Tectonic evolution of the Khoy ophiolitic complex, NW Iran

The Khoy Ophiolitic Complex (KOC) as a part of Tethyan, Izmir-Ankara- Erzincan and Bitlis-Zagros sutures of South East (SE) Turkey is broadly exposed around Khoy region (NW Iran). This complex comprises dismembered fragments of mantle lithosphere, obducted oceanic lithosphere and parts of volcanic arc remnants. The Khoy Ophiolitic Complex can be structurally divided into two major eastern and w...

Plate tectonic reconstructions with continuously closing plates

We present a new algorithm for modeling a self-consistent set of global plate polygons. Each plate polygon is composed of a finite list of plate margins, all with different Euler poles. We introduce a "Continuously Closed Plate" (CCP), such that, as each margin moves independently, the plate polygon remains closed geometrically as a function of time. This method solves emerging needs in computa...
