Mantle hydration and Cl-rich fluids in the subduction forearc

In the forearc region, aqueous fluids are released from the subducting slab at a rate depending on its thermal state. Escaping fluids tend to rise vertically unless they meet permeability barriers such as the deformed plate interface or the Moho of the overriding plate. Channeling of fluids along the plate interface and Moho may result in fluid overpressure in the oceanic crust, precipitation o...

Lithium Abundance and Isotope Systematics of Forearc Serpentinites, Conical Seamount, Mariana Forearc: Insights Into the Mechanics of Slab-Mantle Exchange During Subduction

Formation of forearc basins and their influence on subduction zone earthquakes

Recent observations of an association between forearc basins and slip during subduction thrust earthquakes suggest a link between processes controlling upper plate structure and seismic coupling on the subduction-zone thrust fault. We present a mechanism for the formation of these basins where sedimentation occurs on landward-dipping segments of the subduction wedge, which itself is actively gr...

A Study on the Use of Social Media to Understand Consumer Preference: The Case of Starbucks

The paper seeks to identify Starbuck's experience in using social media, understand how social media is linked to customer knowledge management, and assess how social media services could have contributed to Starbucks success. Starbucks demonstrates versatility to engage customers and support different part of customer knowledge management strategy through various social media platforms, such a...
