  CONTENTS - Regions and deposits to be visited
Andean Porphyries 2017 will provide a comprehensive overview of the scope and variability of the occurrence of 'porphyry related' deposits, and their common and contrasting characteristics.   It will 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 laterally contiguous, geotectonic zones
    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 Colombia in the north,
  • deposits spread across the principal temporal clusters of emplacement,
   
from Jurassic to Miocene/Pliocene.

The tour will be split into two parts, the first from central Chile to southern Peru, the second from central Peru, through Ecuador to Colombia, punctuated by a 3 day break for those wishing to attend the  proEXPLO 2017  conference in Lima from 8 to 10 May. This conference is to address Andean metallogeny, geology and exploration, and the main ore deposits located in Peru and the region.
Participants may take any 3 or more days, up to the full tour, as suits their budget, availability and interest.
