0,Si, Al, Mg, AND Fe WERE DETERMINED BY USING 14 MeV NEUTRON ACTIVATION ANALYSIS,SEE EHMANN AND MORGAN (1971). THE ELEMENTS Ti, Ca, Mn AND Na ARE DETERMINED BY 252 Cf THERMAL NEUTRON ACTIVATION SEE JANGHORBANI ET AL.,1973). THE Ca ABUNDANCES ARE DETERMINED BY A CYCLIC ACTIVATION TECHNIQUE AND WHILE THE ABUNDANCES OF Ti,Mn AND Na ARE TYPICALLY BASED ON THREE REPLICATE ANALYSES. ABUNDANCES OF TRACE ELEMENTS WERE DETERMINED IN SOME OF THE SAMPLES BY INSTRUMENTAL REACTOR NEUTRON ACTIVATION. FOR A NUMBER OF SAMPLES,Fe WAS DETERMINED BOTH BY 14 MeV AND REACTOR THERMAL NEUTRON ACTIVATION. SPLITS OF STANDARD ROCKS BCR-1 AND W-1 WERE USED AS STANDARDS FOR THE TRACE ELEMENT DETERMINATIONS. SELECTED ABUNDANCES IN THE STANDARD ROCKS WERE TAKEN FROM FLANAGAN (1969) AND FLEISCHER (1969)
