Randomized trial evaluates magma reservoir assembly in Carlingford Complex, indicating variability in emplacement regimes.

Key Points

This research aims to understand the contrasting models of subvolcanic magma reservoir assembly throughout different phases of crystallization and replenishment.
Integrated field observations, microstructural analysis, and geochemical assessments conducted on the Carlingford Complex.
Identification of four stratigraphic zones to analyze emplacement behavior and modifications in crystal fractions.
High-resolution sampling of outcrop and drill core material to investigate the intrusive processes and their evolutionary history.
Identification of a previously unrecognized Lower Zone indicating a liquid-dominated environment with evidence of pulsed replenishment.
Observation of a Middle Zone characterized by rapid inflation with trends suggesting crystal settling and convection.
Upper Zones show varied emplacement dynamics, indicating alternating liquid and crystal-dominated regimes over short intervals.
