Chlorine is a key volatile in magmatic and volcanic systems, being a major consumer of atmospheric ozone and an important ligand for metal transport. Despite chlorine's importance however, the combined effects of melt composition and H₂O o...
Melt-bearing nodules from Tenerife reveal magma reservoir diversity prior to caldera-forming eruptions [0.03%]
泰德列岛熔岩结核揭示了形成破火山口之前的火山水库多样性

Partially crystalline nodules are occasionally discovered within breccias linked to large ignimbrite-forming eruptions, providing evidence of the fragmentation of the plutonic reservoir and conduit system during such eruptions. These nodule...
Impact of intragrain chemical heterogeneities on 40Ar/39Ar and 87Rb-87Sr white mica dates [0.03%]
颗粒内化学不均一性对白云母的40Ar/39Ar和87Rb-87Sr定年的影响

Vidar Jakobsson et al.
White mica commonly yields younger 40Ar/39Ar dates than 87Rb-87Sr isochron dates in greenschist to amphibolite facies rocks, which are often interpreted as 40Ar/39Ar cooling dates. However, recent petrochronological studies showed that youn...
Apatite saturation revisited: new model formulations and applications to igneous rocks [0.03%]
关于磷灰石饱和的新思考：新模型的表述及在火成岩中的应用

Apatite is the primary phosphate mineral in the Earth's crust and is present in a range of intrusive and extrusive igneous rocks, typically at minor to trace quantities. Similarly, apatite is a stable phase in many equilibrium crystallizati...
Phase equilibria modelling of trace element evolution in arc magmas: implications for petrogenesis and copper porphyry indicators [0.03%]

Trace element ratios in arc magmas are widely used to infer petrogenetic conditions, particularly those associated with porphyry-forming versus barren systems. However, quantitatively linking whole-rock signatures to pressure, water content...
Linking crystal shape and dynamic undercooling: a new framework for inferring magmatic crystallization histories [0.03%]
晶体内形与动态过冷之间的联系：推断岩浆结晶历史的新框架

Amanda Lindoo et al.
Magmas contain crystals exhibiting diverse shapes and sizes, yet the relationship between crystal shape (specifically aspect ratio) and undercooling ([Formula: see text]), the driving force for crystallization, remains poorly constrained. C...
Melt reactions and timescales of melting in pelitic rocks-a case study from the Garhwal Himalaya [0.03%]

The dehydration of antigorite is an important reaction in subduction zones with implications on both geochemical and geophysical processes. In this experimental study we focus on the onset of antigorite dehydration and investigate various c...
Cooling rates and melt extraction timescales determined by diffusion chronometry on shallow crustal plutonic rocks [0.03%]
