The structure and petrology of the Cnoc nan Cuilean Intrusion, Loch Loyal Syenite Complex, NW Scotland [PDF]
, 2013 In NW Scotland, several alkaline intrusive complexes of Silurian age intrude the Caledonian orogenic front. The most northerly is the Loch Loyal Syenite Complex, which is divided into three separate intrusions (Ben Loyal, Beinn Stumanadh and Cnoc nan ...

Computing Elastic Moduli of Igneous Rocks Using Modal Composition and Effective Medium Theory
Geosciences, 2022 Elastic constants of rock materials are the basic parameters required for modeling the response of rock materials under mechanical loads. Experimental tests for determining these properties are expensive, time-consuming and suffer from a high uncertainty

Does Zircon Shape Retain Petrogenetic Information?
Geochemistry, Geophysics, Geosystems, 2023 Zircon shape is commonly reported during geochronology and geochemistry analyses of igneous, metamorphic, and sedimentary rocks, but the relationship of zircon shape to primary growth environmental conditions remains poorly constrained.

Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts
Advanced Science, EarlyView.The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that
