In the first place, most chemists work with materials whose chemical formulae are fairly simple, and in which the ratio of the numbers of atoms of one kind to the numbers of atoms of another are small integers, or fractions of small integers. Among such compounds are NaCl, Al203 and Si02• By contrast, the geochemist often stud…
Orientation studies indicate that stream-sediment geochemistry is a potentially useful exploration tec~ique in the Kepala Burung region of Irian Jaya, Indonesia.
