Abstract:
The current research was undertaken in order to clarify the regional structural setting of the batholith, the mechanism of emplacement o~ successive plutons and the extent of the control exerted by the envelope fracture pattern on the contact form of individual plutons. Regional mapping in Ancash shows that , in the Albian, a rapidly subsiding trough filled with a great thickness of volcanic caterial while, to the east, thinner and more condensed volcanic strata interdigitated with sediments on the western margin of the Peruvian miogeosyncline.The line of facies divide between the two troughs is concurrent with the axis of a large monoclinal structure which is thought to have been generated by a reversal of movement, with uplift along the fault - bound margins of the earlier basins. Gabbro injection accompanied the deformation which may reflect the generation and accumulation of batholithic magmas at greater depth.
