Quartz-muscovite replacement
of feldspars in the envelopes of veins grading into white quartz-kaolinite alteration, Valley Copper, British Columbia, Canada.
Synopsis:
This course is designed for exploration and remote sensing geologists.
The course outlines the major styles of alteration and addresses best
practices for their description in the field. An emphasis is placed
on mapping mineral assemblages that are then integrated in to prospect
and ore deposit models. The course covers porphyry and epithermal
styles of alteration including both high and low sulfidation environments.
Techniques covered include field descriptions, short wave infrared
(SWIR) spectroscopy using PIMA, petrography and SEM analysis. Workshops
are typically one day, with additional days added for practical exercises.
Practical
Exercises:
Several practical exercises are available, ranging from suites of
characterized hand samples representing various ore-deposit environments
to field exercises at the client's project area.
