Wellington Meeting – Jeffrey Hedenquist

5:30 pm Tuesday 1 March 2016, Straterra, 93 The Terrace, Wellington

Speaker: Jeffrey W Hedenquist, Principal, Hedenquist Consulting Inc, Ottawa, Canada

Relation of advanced argillic alteration to epithermal and porphyry deposits
Acidic (pH <2) condensates of vapors released from shallow magmas form hypogene advanced argillic alteration that may host subsequent high-sulfidation epithermal ore.  Where a lithologic unit is altered, this lithocap alteration overlies, and is commonly offset from, the causative intrusion and potential porphyry Cu mineralization.  Study of vapors and condensates from active volcanoes in Japan and New Zealand provides insight into the genesis of the advanced argillic alteration.

Geological, structural and topographic variations between systems lead to variations in the characteristics of lithocaps and the potential for and nature of high-sulfidation mineralization.  The common upward flaring of advanced argillic alteration zones is due to increased reactivity with decreasing temperature.  High-temperature alteration (pyrophyllite, diaspore, natroalunite plus muscovite) is proximal, whereas lower temperature alteration (dickite, kaolinite, K-alunite, and illite to interstratified clays) is more distal.  Lithocaps develop in areas with near-horizontal permeable lithologies, and in relatively high-relief settings these lithocaps may host high-sulfidation mineralization that is offset (1+ km) from the underlying causative intrusion and potential porphyry ore deposit.  Such lateral offset of lithocap alteration is common in porphyry systems, and this possibility must be appreciated to efficiently assess the potential for both lithocap-hosted ore as well as deeper porphyry-related ore.

Where: Straterra, 93 The Terrace, Wellington

When: 5:30 pm (drinks) for a 6 pm presentation, Tuesday 1 March
