About this document
Perubar VHMS Deposit: Cretaceous Insights by Kenneth E. Hilario R is a document available to read on EtoBox.
The document summarizes research on the Perubar VHMS (volcanic-hosted massive sulfide) deposit in central Peru. Precise dating of volcanic rocks and intrusions associated with the deposit indicate formation between 67.89-69.71 million years ago during Late Cretaceous arc volcanism and basin subsidence. Isotopic analysis suggests the ore minerals precipitated from a hydrothermal fluid that mixed with seawater at the seafloor. The deposit likely formed in an intra-arc pull-apart basin during oblique subductio
