摘要: Rare earth abundances were determined by neutron activation in twenty Hawaiian lavas and one diabase of known chemical mineralogical compositions. These results demonstrate a systematic relationship between the absolute or relative rare petrochemistry these rocks. Three distinct lava groups are recognized. correspond to: (1) tholeiites, (2) alkali series, (3) nepheline-melilite basalts.
