OLIVINE-BEARING QUARTZ-MONZONITE FROM KIANDRA. Party 
seated origin the association of olivine and quartz must 
be necessarily exceptional. 
EXPLANATION OF PLATE XIV. 

Magnification in each case 14} diameters. 
Fig. 1. Quartz-monzonite. Ordinary light. Note the augite in 
the lower left-hand corner, filled with olivine granules 
and surrounded by a hornblende rim, 
Fig. 2. Same as Fig. 1, between crossed nicols. The interstitial 
material, wrapping round the plagioclase in typical 
monzonitic fashion is largely orthoclase, with a little 
quartz. 
Fig. 3. Monzonite-porphyry. Ordinary light. The plagioclase 
of the first generation is notably free from inclusions and 
the augite phenocrysts have no hornblende rim. 
Fig. 4. Same as Fig. 3, between crossed nicols, showing the dis- 
position of the groundmass. Note the multiple twinning 
and the composite natuse of the pyroxene phenocryst.
