We analyze the geological evolution of these distinct blocks, including the Duarte Complex, the Maimón Formation, and the Tireo Formation, while examining how strike-slip fault systems like the Enriquillo-Plantain Garden fault shaped the modern Hispaniola microplate. The structural history of the region is defined by an uplifted belt of metamorphic rocks where a major fault separates the Duarte and Maimón Formations, serving as the site for the emplacement of the Loma Caribe peridotite (ResearchGate, n.d.). Our investigation delves into the stratigraphy of the central Dominican Republic, detailing late magmatic emanations of epidote within volcanic rocks and the presence of Lower Cretaceous black limestones (ResearchGate, n.d.). We also contrast the deformation levels of the Cevicos Limestone against older Oligocene formations (Cooke, 1921) and utilize microfossil data from the Tireo Formation to constrain the timing of arc development (Pessagno & Bronnimann, n.d.). Furthermore, this technical overview covers the metallogenic evolution of the island, from world-class high-sulfidation epithermal gold-silver deposits at Pueblo Viejo to the PGE contents found within Ni-laterite deposits at Falcondo (Aiglsperger et al., 2014). By synthesizing data from the SYSMIN Project, we illustrate how transpressive deformation has created characteristic structures such as restraining bends and flower zones that define the island's unique tectonic collage (SYSMIN, n.d.).
