<p> The Au, Pt, Pd and Ir content of Fred's flow (a
layered komatiite flow), Theo's flow (a layered tholeiite
flow) and two peridotitic komatiite flows at Pyke Hill, all
from Munro Township, were determined using radiochemical
neutron activation analysis. In addition, the potential of
Pyke Hill peridotitic komatiites as a gold source was evaluated.
X-ray fluorescence spectroscopy, atomic absorption
spectroscopy and a Leco automatic carbon determinator were
used to determine major and trace element content in a
total of 43 samples. </p> See Chart in text. <p> The peridotitic komatiite magma at Pyke Hill has the most mantle like proportions of Pt and Pd. None of the flows
studied have been saturated with respect to sulphur. No
leaching of siderophile and chalcophile elements has taken
place prior to extrusion and cooling.</p> <p> The low gold content of the unaltered Pyke Hill
peridotitic komatiites (average 2.8 ppb) do not make them
obvious source rocks for gold deposits. </p> / Thesis / Master of Science (MSc)
