Cyprus exposes a world-class ophiolite containing a fossil ridge-transform system that formed in an (ultra)slow spreading supra-subduction zone setting. The stratigraphic completeness and outcrop quality make it uniquely suited for studying its (de)formation history and associated magmatic and hydrothermal processes. The Arakapas Transform Fault separates two distinct domains of the ophiolite; in the north, the Troodos ophiolite largely conforms to the Penrose stratigraphy, while in the south, the Limassol Forest Complex (LFC) is characterised by anomalous stratigraphic and structural contacts.
In this study, the intrusive history of the sheeted dike complex in the Limassol Forest is unravelled on the basis of field observations, petrology, and geochemistry, and compared with the sheeted dike complex of the Troodos ophiolite. Field descriptions and the relative timing of dike sets in the Limassol Forest and Troodos are expanded with geochemical and petrological characterization of selected samples using optical and scanning electron microscopy combined with whole-rock, trace, and rare-earth elemental analyses.
The geological, geochemical, and petrological data will be used to determine and compare the evolution of the Limassol Forest Complex and the Troodos ophiolite. Their heterogeneous evolution, and the influence of the Arakapas Transform Fault, provide insights into the interplay between tectonic, magmatic, and hydrothermal processes active at slow spreading ridge-transform systems.
