Inferences about sheet intrusion emplacement mechanisms have been built largely on field observations of intrusion tip zones: magmatic systems that did not grow beyond their observed state. Here we use finite element simulation of elliptical to super

Previous studies have suggested a link between rates of sea-level variation and eruptions globally [McGuire et al., 1997], with Satow and coauthors [2021] presenting the first detailed comparison between sea-level change and eruptive history for a si

A common method of characterising dikes is to plot their measured maximum thickness (T) against their horizontal length (L). This method has been applied widely to fault systems to determine critical mechanical controls on intraplate fault evolution,

Magmatic sheet intrusions are commonly segmented, across multiple scales, with preserved segments typically interpreted as representing an early stage of intrusion growth. Intrusion propagation has long been associated with linear elastic host rock d

In linear elastic fracture mechanics (LEFM), veins, dikes, and sills grow in length when the stress intensity factor [K_I] at the tip reaches a critical value: the host rock fracture toughness [K_Ic]. This criterion is applied broadly in LEFM models

Several methods are investigated for the quantitative analysis of a range of Sn-W sheeted vein systems from southwest England and Spain. The methods are based on fractal concepts and include the measurement of vein thickness and spacing distributions
