Recently,
MDRU developed a carbon-
ate isotope analyzer that is an alternative
to traditional mass spectrometry for tar-
geting carbonate-hosted deposits. "The
carbonate isotope analyzer is less expen-
sive, more portable and easier to use than
a mass spectrometer," says Spisar. "It is
capable of producing 100 results per day,
compared to 10 results per day using a
mass spectrometer."
These are all present-day technolo-
gies. But what about the technologies
of tomorrow? Danae Voormeij has been
putting together a wish list.
"As an exploration geologist active
in tropical latitudes, I deal with a thick
weathering rind, called regolith, that lies
as a layered cover between my feet and
a gold deposit at depth," Voormeij says.
Regolith in the tropics is typically about
four to five metres thick and includes
