Distribution and geochemical variations among paleogene volcanic rocks from the north-central Lut block, eastern Iran
The Lut block in eastern Iran is a micro-continental block within the convergent orogen between the Arabian, Eurasian and Indian plates. Large areas of the north-central, eastern, and western Lut block are covered by volcanic rocks of Paleogene, Neogene and Quaternary age. Peak volcanic activity took place in the north-central part of the Lut block during the Eocene, and then dramatically decr...

متن کاملOrographic barriers, high-resolution TRMM rainfall, and relief variations along the eastern Andes
[1] Quantifying the degree to which tectonic and erosive processes shape landscapes is key to understanding the evolution of tectonically active mountain belts. Here we explore the interplay of these two processes along the humid, eastern flank of the South American Andes. We use high-resolution Tropical Rainfall Measurement Mission (TRMM) and SRTM data to characterize elevation, relief, and hi...
متن کاملOceanic spreading center–hotspot interactions: Constraints from along-isochron bathymetric and gravity anomalies
We analyzed bathymetric and gravity anomalies along present and paleoaxes of oceanic spreading centers influenced by the Iceland, Azores, Galápagos, Tristan, and Easter hotspots. Residual bathymetry (up to 4.7 km) and mantle Bouguer gravity (up to2340 km) anomalies are maximum at on-axis hotspots and decrease with increasing ridge-hotspot separation distance (D), until becoming insignificant at...
