Origin of calcite by magma mixing in mingled rocks of the Ghansura Rhyolite Dome, Bathani volcano-sedimentary sequence, eastern India

Mineralogia
The Ghansura Rhyolite Dome (GRD) is an integral part of the Bathani volcano-sedimentary sequence (BVSs), which in turn is a vital component of the Chotanagpur Granite Gneiss Complex (CGGC), eastern India.

Genome‐wide association and interaction analysis for proliferative retinopathy in adults with type 2 diabetes born during famine: The DOLCE study in Ukraine

Acta Ophthalmologica, EarlyView.
Abstract Purpose Proliferative diabetic retinopathy (PDR) is one of the leading causes of blindness in working‐age adults. We have previously shown that the risk of PDR is significantly elevated in individuals with intrauterine exposure to famine. However, the genetic mechanisms mediating this association remain unknown.

Plagioclase as evidence of magmatic evolution in the Zafarqand porphyry copper deposit, NE Isfahan

Journal of Economic Geology, 2018
Introduction Chemical and textural zoning patterns preserved in plagioclase phenocrysts can provide useful information on parameters that constrains the changing melt compositions in the magma systems.

Hybridization in the subvolcanic Jaala-Iitti complex and its petrogenetic relation to rapakivi granites and associated mafic rocks of southeastern Finland [PDF]

Bulletin of the Geological Society of Finland, 1995
The 1630 Ma Jaala-Iitti complex is an example of bimodal rapakivi granite magmatism in which the interaction of granite and diabase magmas have led locally to hybridization.

Topology‐based Visual Analysis of Hydrothermal Plumes

Computer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Quantification of Sulfur Speciation in Apatites: Comparison of the XAS, XPS and EPMA Techniques

Geostandards and Geoanalytical Research, EarlyView.
Key Points Sulfur speciation in apatites has been determined by S K‐edge X‐ray absorption near‐edge structure (XANES) spectroscopy, S 2p X‐ray photoelectron spectroscopy (XPS) and electron probe microanalysis (EPMA). XANES provides the most sensitive and accurate quantification of sulfur speciation.

Apatite as a Proxy for Reconstructing Magma Mixing Histories in Granitoids

Geochemistry, Geophysics, Geosystems
Apatite is a common accessory mineral in granites and mafic microgranular enclaves (MMEs), and its textural and compositional characteristics can record dynamic magmatic evolution processes.

U–Pb Dating of Cambrian Magmatism in the Pinerolo‐Sanfront Unit, Dora‐Maira Massif (Western Alps)

Terra Nova, EarlyView.
ABSTRACT The Pinerolo‐Sanfront Unit (PSU), the structurally lowest tectonic unit of the Dora‐Maira Massif (Western Alps), has been regarded as a monocyclic unit composed of Permo‐Carboniferous sediments and Permian granitoids that were metamorphosed during the Alpine orogeny.

Mechanism of magma mixing at Glass Mountain, Medicine Lake Highland Volcano, California [PDF]

, 1979
Mixing of basaltic and rhyolitic magmas at Glass Mountain appears to have been driven by vesiculation of basaltic magma as it intruded a rhyolitic magma chamber. Rapid cooling of basaltic magma formed a mafic foam which floated and became concentrated at
