The trace-element and isotope geochemistry of rutile are robust tools to determine metamorphic temperatures, age, and host-/source lithologies. The use of rutile as single grain indicator for pressure, temperature, time and composition (P-T...
Plutonic xenoliths from Martinique, Lesser Antilles: evidence for open system processes and reactive melt flow in island arc crust [0.03%]
来自马提尼克岛的小安的列斯群岛弧火山岩中的深成捕虏体：开放体系过程及反应熔体流动作用证据

George F Cooper
The Lesser Antilles Volcanic Arc is remarkable for the abundance and variety of erupted plutonic xenoliths. These samples provide a window into the deeper crust and record a more protracted crystallisation history than is observed from lava...

The 168 m-thick Shiant Isles Main Sill is a composite body, dominated by an early, 24 m-thick, picrite sill formed by the intrusion of a highly olivine-phyric magma, and a later 135 m-thick intrusion of olivine-phyric magma that split the e...

The ascent of hydrous magma prior to volcanic eruptions is largely driven by the formation of H2O vesicles and their subsequent growth upon further decompression. Porosity controls buoyancy as well as vesicle coalescence and percolation, an...
Boron isotope record of peak metamorphic ultrahigh-pressure and retrograde fluid-rock interaction in white mica (Lago di Cignana, Western Alps) [0.03%]
意大利西阿尔卑斯湖白云母峰期变质超高压及流体-岩石相互作用的硼同位素记录（Cignana Lake, Western Alps）

This study presents boron (B) concentration and isotope data for white mica from (ultra)high-pressure (UHP), subduction-related metamorphic rocks from Lago di Cignana (Western Alps, Italy). These rocks are of specific geological interest, b...
Braided peridotite sills and metasomatism in the Rum Layered Suite, Scotland [0.03%]

The Rum Eastern Layered Intrusion (ELI; Scotland) is an open-system layered intrusion constructed of 16 macro-rhythmic units. Each of the macro-rhythmic units consists of a peridotite base and a troctolite (± gabbro) top, previously attrib...
The thickness of the crystal mush on the floor of the Bushveld magma chamber [0.03%]
布什维尔德岩浆房底板结晶 Mush 的厚度分布及对铂族元素控制意义研究

Marian B Holness
The thickness of the crystal mush on magma chamber floors can be constrained using the offset between the step-change in the median value of dihedral angles formed at the junctions between two grains of plagioclase and a grain of another ph...
Petrological and experimental evidence for differentiation of water-rich magmas beneath St. Kitts, Lesser Antilles [0.03%]
圣基茨岛下富水岩浆分异的岩石学和实验证据

Elena Melekhova et al.
St. Kitts lies in the northern Lesser Antilles, a subduction-related intraoceanic volcanic arc known for its magmatic diversity and unusually abundant cognate xenoliths. We combine the geochemistry of xenoliths, melt inclusions and lavas wi...
Deducing the source and composition of rare earth mineralising fluids in carbonatites: insights from isotopic (C, O, 87Sr/86Sr) data from Kangankunde, Malawi [0.03%]
马拉维坎甘昆德碳质碳酸岩中稀土矿化流体来源和组成的同位素地球化学研究
Sam Broom-Fendley,Frances Wall,Baruch Spiro et al.
Sam Broom-Fendley et al.
Carbonatites host some of the largest and highest grade rare earth element (REE) deposits but the composition and source of their REE-mineralising fluids remains enigmatic. Using C, O and 87Sr/86Sr isotope data together with major and trace...
The elastic solid solution model for minerals at high pressures and temperatures [0.03%]
高压高温下矿物的弹性固溶体模型

Non-ideality in mineral solid solutions affects their elastic and thermodynamic properties, their thermobaric stability, and the equilibrium phase relations in multiphase assemblages. At a given composition and state of order, non-ideality ...
