Coupled magmatic and tectonic activity plays an important role in high-temperature
hydrothermal circulation at mid-ocean ridges. The circulation patterns for such systems have …

Over the past two decades, a significant number of discoveries of ancient zircon xenocrysts
in ocean-floor magmatic rocks have been reported. These findings provide compelling …

Along ultraslow-spreading ridges, where oceanic tectonic plates drift very slowly apart,
conductive cooling is thought to limit mantle melting and melt production has been inferred …

The formation of abyssal serpentinites leads to deep changes of the oceanic lithosphere
rheology and geochemistry, hence playing a key role on geodynamic and geochemical …

A newly confirmed hydrothermal sulfide ore hosted by ultramafic rocks was identified in the
Tianzuo field on the Southwest Indian Ridge. In this study, detailed mineralogy …

Mid-ocean ridges display tectonic segmentation defined by discontinuities of the axial zone,
and geophysical and geochemical observations suggest segmentation of the underlying …

Southwest Indian Ridge (SWIR) is a typical oceanic ultraslow spreading ridge with intensive
hydrothermal activities. The microbial communities in hydrothermal fields including primary …

Abstract 809 deep IODP Hole U1473A at Atlantis Bank, SWIR, is 2.2 km from 1,508‐m Hole
735B and 1.4 from 158‐m Hole 1105A. With mapping, it provides the first 3‐D view of the …

Abstract The Southwest Indian Ridge (SWIR) is characterized by an ultraslow spreading
rate, thin crust, and extensive outcrops of serpentinized peridotite. Previous studies have …

Ultraslow spreading ridges form the slowest divergent plate boundaries and exhibit distinct
spreading processes in volcanically active magmatic sections and intervening amagmatic …
