  CONTENTS - Regions and deposits
Andean Porphyries 2017-18 has been designed in two parts to provide a comprehensive overview of the scope and variability of the occurrence of 'porphyry related' deposits, and their common and contrasting characteristics.   The combined itineraries are planned to include:
  • each of the styles of porphyry related deposits & commodity groupings,
    including 'classic' porphyry, porphyry-breccia, porphyry-skarn, porphyry-
    epithermal & supergene deposits  of  Cu-Mo±Zn±Au, Cu-Au & Au±Cu,
  • the  three differing, distinct and longitudinally contiguous, geotectonic
that host significant porphyry mineralisation in the Andean Orogen,
    the northern, Peruvian and central Andes,
  • a representative selection of deposits,   from south-central Chile in the
    south, to northern Ecuador in the north,
  • deposits spread across the principal temporal clusters of emplacement,
from Cretaceous to Miocene/Pliocene.
