Geochemistry, geochronology and petrogenesis of Maya Block granitoids and dikes from the Chicxulub Impact Crater, Gulf of México: Implications for the assembly of Pangea Vrije Universiteit Brussel
The Late Paleozoic tectono–magmatic history and basement of the Maya block are poorly understood due to the lack of exposures of coeval magmatic rocks in the region. Recently, IODP–ICDP Expedition 364 recovered drill core samples at borehole M0077 from the peak ring of the Chicxulub impact crater, offshore of the Yucatán peninsula in the Gulf of México, have been studied comprehensively. In the lowermost ~600 m of drill core, impact–deformed ...
