The Earth as a planetary system has experienced significant change since its formation c.
4.54 Gyr ago. Some of these changes have been gradual, such as secular cooling of the …

At subduction zones, crustal material enters the mantle. Some of this material, however, is
returned to the overriding plate through volcanic and plutonic activity. Magmas erupted …

Lawsonite‐bearing metamorphic/metasomatic rocks form at high‐pressure–ultrahigh
pressure (HP–UHP) and low‐temperature (LT) conditions, commonly in Pacific‐type …

The theory of plate tectonics is widely accepted by scientists and provides a robust
framework with which to describe and predict the behavior of Earth's rigid outer shell–the …

Jadeitite is a relatively rare, very tough rock composed predominantly of jadeite and typically
found associated with tectonic blocks of high-pressure/low-temperature metabasaltic rocks …

Newly recognized occurrences of ultrahigh-pressure (UHP) minerals including diamonds in
ultrahigh-temperature (UHT) felsic granulites of orogenic belts, in chromitites associated with …

The gemstones jadeite and ruby generally form as a result of the plate tectonic processes
subduction and collision. Jade made of jadeite (jadeitite) forms when supercritical fluids …

In this study, we have deduced the thermal history of the subducting Neotethys from its
eastern margin, using a suite of partially hydrated metabasalts from a segment of the …

New occurrences of jadeitite and jadeite-rich rocks have been discovered in the Rio San
Juan Complex (RSJC) of the northern Dominican Republic in serpentinite mélanges …

Fluid is a key agent for the mass transfer between the subducting slab and the mantle
wedge, which greatly affects the evolution of the crust-mantle system at convergent plate …
