Field Trip Report—Chile, May 2005<br />

The barren Atacama Desert <strong>of</strong> northern<br />

Chile was a contrast to the damp<br />

Vancouver spring for the participants <strong>of</strong><br />

the 2005 University <strong>of</strong> British Columbia<br />

<strong>SEG</strong> student chapter field trip. The trip,<br />

from April 27 to May 12, was arranged<br />

with the goal <strong>of</strong> touring world-class porphyry<br />

and epithermal deposits <strong>of</strong> northern<br />

Chile and to gain an appreciation<br />

for the geologic evolution <strong>of</strong> a continental<br />

magmatic arc.<br />

Seventeen individuals<br />

participated<br />

throughout the<br />

entire trip, including<br />

six industry members<br />

and 11 students<br />

and employees from<br />

the university. Two<br />

additional industry<br />

representatives and<br />

sevearl geology students<br />

from the<br />

Universidad<br />

The “Top End Geo-Explorer Tour”<br />

July 11–22, 2005<br />

Six members <strong>of</strong> the University <strong>of</strong><br />

Tasmania <strong>SEG</strong> student chapter took part<br />

in the chapter’s main field trip for 2005:<br />

the “Top End Geo-Explorer Tour” <strong>of</strong> the<br />

Northern Territory, Australia. The group<br />

had a distinctly international feel, with<br />

two Australians, and one each from the<br />

UK, Russia, Zambia, and Thailand.<br />

After gathering in Darwin, the group’s<br />

first stop was the enigmatic Browns polymetallic<br />

deposit in the Rum Jungle mineral<br />

field, located south <strong>of</strong> Darwin, near<br />

the Litchfield National Park. This was followed<br />

by a day at Tom’s Gully gold<br />

mine, a shear-hosted gold deposit east <strong>of</strong><br />

Darwin. The group spent the following<br />

day gaining an understanding <strong>of</strong> the<br />

regional geology <strong>of</strong> the Ranger uranium<br />

mine by visiting numerous key exposures<br />

in the Kakadu National Park, before<br />

spending the next day at Ranger itself.<br />

The historic Pine Creek region was visited<br />

en-route as the group travelled south to<br />

A day’s drive south and east followed<br />

as the group travelled out to Cape Crawford<br />

to visit first the Merlin diamond field<br />

and then the giant HYC McArthur River<br />

Zn-Pb-Ag mine. Another day’s drive west<br />

and south, and the group arrived in the<br />

historic town <strong>of</strong> Tennant Creek and visited<br />

the Chariot Gold iron-oxide coppergold<br />

(IOCG) deposit. The last day <strong>of</strong> the<br />

trip involved a visit to the Devil’s<br />

Marbles enroute to Alice Springs.<br />
