...-composition volcanic rocks in and adjacent to the Zamora batholith to the Misahuallí unit of the Chapiza Formation. However, Drobe et al. (2013) argued for division of the widespread Misahuallí volcanic rocks on the basis of whether they are intruded by or unconformably overlie the Zamora batholith. Those...

... and shallow-marine volcaniclastic sediments (Chapiza and Tambococha formations) ( Diaz et al. 2004 ). The Late Triassic–Early Jurassic rifting was induced by the break-up of Pangaea ( Jaillard et al. 1995 ). It was followed by a Middle–Late Jurassic back-arc extensional regime related to the onset...
