Complex basin development in a wrench-dominated back-arc area: Tectonic evolution of the Crati Basin, Calabria, Italy

Source area and tectonic control on alluvial-fan development in the Miocene Fohnsdorf intramontane basin, Austria

Middle Miocene alluvial fans in the intramontane Fohnsdorf Basin of the Eastern Alps originated along normal faults and linked strike-slip faults in a continental half-graben setting. The fans display considerable facies differences. Debris flows of the Rachau fan are characterized by a sandy matrix and large boulders, whereas debris flows of the Apfelberg fan are characterized by higher silt a...

Long-Term Stability of Back-Arc Basin Hydrothermal Vents

Since the discovery of hydrothermal vents 40-years ago, long-term time-series have focused on mid-ocean ridge systems. Based on these studies, hydrothermal vents are widely considered to be dynamic, ephemeral habitats. Under this premise, national, and international regulatory bodies are currently planning for the commercial mining of polymetallic sulfide deposits from hydrothermal vents. Howev...

Mesozoic Basin Development and Tectonic Evolution of the Dabieshan Orogenic Belt, Central China

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...

Post-tectonic landscape evolution of a coupled basin and range: Pinaleño Mountains and Safford Basin, southeastern Arizona

The Pinaleño Mountains and adjacent Safford Basin are a landscape defined by the extensional tectonics of the Basin and Range physiographic province. However, over the last ~4 m.y., this coupled basin and range have been actively degrading in the absence of widespread regional extension. While rates of relief generation and upland erosion during active subsidence ca. 12–5 Ma are reflected in th...
