Estimating the thickness of an ultrahigh-pressure (UHP) terrane: insights from phase equilibria modelling and Zr-in-rutile thermometry, Dulan area, North Qaidam terrane, China
The North Qaidam UHP terrane, in western China, exposes minor UHP eclogites hosted by ortho- and paragneisses. In the southeastern part of the terrane, the Dulan area exposes eclogite with the mineral assemblage Grt + Omp ± Ky ± Ph ± Zo ± Qz/Coe. LASS U-Pb analyses of zircons yield weighted mean …

Investigations of Trace Element Titanium in Silica Minerals
<p>Quartz is a common mineral in many igneous, metamorphic, and sedimentary rocks because it is stable over a wide range of pressure (P) and temperature (T) conditions; therefore, quartz is an excellent mineral to target for thermobarometric uses. Thermobarometry is the quantitative determination …

Applications of Elastic Modeling, Thermobarometry, and Thermal History Modeling to (Ultra)high-Pressure Metamorphic Rocks
… regions that produce seismicity and volcanism during plate convergence and ultimately recycle crustal material into the mantle. Since these regions dictate many global scale tectonic and geochemical processes (i.e. orogenesis, volatile flux into the mantle, etc.), it is important to understand the …

Integrating in situ Geochronology and Metamorphic Petrology: An Example from the Gruf Complex, European Central Alps
Understanding the thermal evolution (i.e. the timing, rate, duration, and magnitude of thermal events) within mountain belts has important implications for the geodynamic evolution of both ancient and modern orogenies. Ultra-high temperature (UHT) metamorphism requires geodynamic or tectonic …

The thermal structure of collisional orogens – insights from the Grenville orogen in Canada and Scotland
… collisional orogens provide important time-integrated records of metamorphic, magmatic and deformation processes occurring over timescales of up to hundreds of millions of years. When combined with observations and principles from present-day deformed continental regions, research of …
