aspects of gallium geochemistry in upper mantle-derived lherzolite xenoliths and continental alkaline volcanic rocks
abstract
various aspects of the geochemistry o-f ga in upper
mantle—derived garnet, iherzolite xenoliths (from the
bult-fontein floors mine dump in kimberley, south africa),
spinel iherzolite xenoliths (from mount porndon, australia),
and continental alkaline volcanic rocks (from the freemans
cove, balcones, urach and hegau suites of canada, the u.s.a.,
and germany, respectively) have been investigated. ga
abundances were determined by rnaa. the feasibility of using
epithermal inaa to generate accurate ga data was investigated.
analysis of u.s.g.5. standard granite g—2 suggests
72
that epithermal inaa utilizing 630.1 kev72ga data has the
potential to produce geologically useful ga data. (see document for full abstract)
