Longer aftershocks duration in extensional tectonic settings [PDF]
AbstractAftershocks number decay through time, depending on several parameters peculiar to each seismogenic regions, including mainshock magnitude, crustal rheology, and stress changes along the fault. However, the exact role of these parameters in controlling the duration of the aftershock sequence is still unknown.

Mineral chemistry and thermobarometry of gabbroic rocks from the Pargeh area (NE Qazvin): A key for understanding the crystallization conditions [PDF]
Introduction Mineral chemistry data as well as petrography provide a comprehensive picture of magma crystallization conditions that support the conclusions based on geochemical data. In addition, the chemical composition of minerals such as clinopyroxene,
