Figure 10: Image showing muscovite
crystallinity as deduced from ASTER data and
vectors for the linear zones of iron-oxide
kaolinite phyllic alteration (wavelength
100m) at Tambo South and Tambo V. The
degree of muscovite crystallinity is indicated
by color, with highly crystalline mica (high
temperature) designated as red and poorly
crystalline mica (lower temperature) shown
as blue. Three major zones of higher
crystallinity (higher temperature) are
interpreted. The Tambo South muscovite
zone is of high crystallinity, which is
consistent with the interpretation of a
proximal porphyry centre; the crystallinity of
Tambo V centre is of a lower magnitude,
which may suggest a more distal setting. The
dashed lines indicate interpreted structures
(faults fracture zones) that are inferred to
control hydrothermal alteration and metals
distribution (cf. previous figure).
