Two specimens of lamproite from the Truro-Frankton area were examined for possible indicator minerals. A specimen from Schneiders Gossan contains apatite and one from Truro itself contains sparse rutile. Both minerals will be analysed by microprobe for diagnostic trace elements. Three samples of inclusions from the same specimen collected near DDH Frankton I were examined. Two inclusions consisted of fine grained, possibly chilled facies of lamproite incorporated in a subsequent pulse of magma precipitating coarse grained minerals. The third sample contained inclusions consisting of aggregates of coarse phlogopite flakes probably concentrated from magma carrying primary phlogopite macrocrysts.
