“…The inferred composition of the primitive mantle derived from this study is also shown in Table 2, and compared to the com positions inferred by others. The abundances, with the exception of Cs, are close to other infer red compositions of the primitive mantle (Sun and Nesbitt, 1977;Wood et al, 1979;Sun and McDonough, 1989). …”

“…Moreover, the degree of incom patibility of each of the IE3 elements can be fur ther compared using similar reasoning (Figs. 6k n), resulting in the order of the incompatibility of the elements; This order of the IEs is almost consistent with those previously proposed for basaltic magmas by Wood et al (1979b), Thompson et al (1984) and Sun (1980).…”

New geological, bulk chemical and mineralogical (QEMSCAN and FEG-EPMA) data are presented for albitite-type uranium deposits of the Mount Isa region of Queensland, Australia. Early albitisation of interbedded metabasalt and metasiltstone predated intense deformation along D 2 high strain (mylonite) zones. The early sodic alteration paragenetic stage includes albite, riebeckite, aegirine, apatite, zircon and magnetite. This paragenetic stage was overprinted by potassic microveins, containing K-feldspar, biotite, coffinite, brannerite, rare uraninite, ilmenite and rutile. An unusual U-Zr phase has also been identified which exhibits continuous solid solution with a uranium silicate possibly coffinite or nenadkevite. Calcite, epidote and sulphide veinlets represent the latest stage of mineralisation. This transition from ductile deformation and sodic alteration to vein-controlled uranium is mirrored in other examples of the deposit type. The association of uranium with F-rich minerals and a suite of high field strength elements; phosphorous and zirconium is interpreted to be indicative of a magmatic rather than metamorphic or basinal fluid source. No large intrusions of appropriate age outcrop near the deposits; but we suggest a relationship with B-and Be-rich pegmatites and quartz-tourmaline veins.
