New insights into the history and origin of the southern Maya block, SE México: U–Pb–SHRIMP zircon geochronology from metamorphic rocks of the Chiapas massif

Abstract: The histories of the pre-Mesozoic landmasses in southern Mé xico and their connections with Laurentia, Gondwana, and among themselves are crucial for the understanding of the Late Paleozoic assembly of Pangea. The Permian igneous and metamorphic rocks from the Chiapas massif as part of the southern Maya block, Mé xico, were dated by U-Pb zircon geochronology employing the SHRIMP (sensitive high resolution ion microprobe) facility at Stanford University. The Chiapas massif is composed of deformed granitoids and… Show more

“…The Chiapas Massif mostly consists of Permian igneous rocks affected by medium-to high-grade metamorphism and middle to late Miocene intrusions related to the subduction of the Cocos Plate (Damon and Montesinos, 1978;Weber et al, 2007;Molina-Garza et al, 2015). The western flank of the Chiapas Massif is bounded by the left-lateral Tonalá shear zone, which connects to the south to the western termination of the Polochic Fault (Wawrzyniec et al, 2005;Weber et al, 2005).…”

“…Por otro lado, en el noreste, centro y sur de México el arco continental permo-triásico nombrado arco del Este de México (Torres et al, 1999) está relacionado a una zona de subducción con vergencia hacia el este en el margen oeste de Pangea (Torres et al, 1999;Schaaf et al, 2002;Weber et al, 2005Weber et al, , 2007Ratschbacher et al, 2009) pero es establecido en corteza gondwánica. Algunos trabajos proponen que pudiera extenderse probablemente hasta el noroeste de Sudamérica (e.g., Centeno-García y Keppie, 1999), específicamente en Colombia, ya que también han sido reportadas rocas de estas edades en esa parte de la Cordillera (e.g., Pindell y Dewey, 1982;Pindell, 1985;Case et al, 1990).…”
