    In:  Supplement to: Brannon, Joyce C (1985): The degree of heterogeneity in basalts near the Hayes Fracture Zone, Mid-Atlantic Ridge: Holes 561, 562, and 564. In: Bougault, H; Cande, SC; et al. (eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office), 82, 439-447, https://doi.org/10.2973/dsdp.proc.82.121.1985

    Description: Analyses of samples from Chemical Group II, Hole 561; Chemical Group I, Hole 562; and two pillows and a flow from Hole 564 show that the chemical groups and the individual structures are compositionally homogeneous for the data presented here except for the alkalies, Na2O and Cs, and transition metals, FeO and Co, and sometimes Sc and Cr. The scatter in the alkalies is attributed to alteration and the scatter in the transition metals is attributed to a short-range segregation model. Although the pillows and flow from Hole 564 are each compositionally homogeneous, their compositions are distinct from one another. These results cannot support the preliminary interpretation by shipboard scientists that the basalts from Hole 564 comprise a single chemical group.

    Rare earth elements in the sedimentary cycle: a pilot study of the first leg (1982)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: A pilot study with Holocene fluvial sands was undertaken in order to evaluate the effects of source rock composition and climate on natural abundances of rare elements (REE) in the first leg of the sedimentary cycle. We have analysed the medium grained sand fraction of samples collected from first order streams exclusively draining granitic plutons in Montana (semi-arid), Georgia (humid), and in South Carolina (humid). Despite compositional differences between parent plutons the REE distribution patterns (but not the total absolute abundances) of the daughter sands are very similar. Averages of the three areas have a La/Lu ratio of ∼ 103 showing a depletion of heavy REE with respect to an ‘average granite’ (La/Lu = 79) or the composite of North American Shales (NAS; La/Lu = 55). Also, the Eu/Sm ratio in sands from these areas is ∼ 0·22 which is very close to the NAS ratio of 0·21. However, the overall REE distribution of these sands is not similar to that of NAS in any way. We conclude that the major rock type, but neither its minor subdivisions nor the climate (in the source area), controls the REE distribution patterns in first cycle daughter sands. But, the total and the parent rock-normalized abundances of REE in sands from the humid areas are much lower than those in sands from the arid areas.

    Major and trace element chemistry of Boulder 1 at Station 2, Apollo 17 (1975)

    Notes: Abstract Twenty-seven samples of matrix and clast materials from Boulder 1 at Station 2, Apollo 17 have been analyzed for major and trace elements as part of the study of this boulder by Consortium Indomitabile. Both unusual and common types of material have been characterized. Gray and black competent breccia (GCBx and BCBx) and anorthositic breccia (AnBx) have compositions which are common at the Apollo 17 site and were common at the site of boulder formation. Light friable breccias (LFBx) have compositions which are not found at the Apollo 17 site other than in the boulder. Pigeonite basalt is a new type of lunar rock and has characteristics that would be expected of a highland volcanic rock. It is associated with LFBx material, and like LFBx material it is exotic to the Apollo 17 site. Coarse norite is an old primitive rock which is no longer (if ever) found as millimeter fragments at the Apollo 17 site. It was, however, present as millimeter fragments associated with GCBx and BCBx materials at the site and time of boulder formation. Therefore the boulder-forming process combined materials from at least two different localities or vertical strata; at least one of these (LFBx) has not been previously sampled and analyzed.

    Major, minor, and trace element compositions of peridotitic and basaltic komatiites from the precambrian crust of Southern Africa (1976)

    Notes: Abstract Major and trace element compositional data are reported for nine mafic and ultramafic rock samples from the Barberton greenstone belt. Rocks from this province are among the oldest fragments of the Earth's crust (∼3.5 b.y.). The data are consistent with an oceanic crust related origin for these rocks. The high abundances of Ni in these samples make their origin by fractional crystallization of a primitive magma unlikely but are consistent with their generation by partial melting of an upper mantle source. The basaltic samples from the Komati formation can be related by small degrees of partial melting of a primitive upper mantle source to the peridotitic komatiite which probably derived from much more extensive partial melting of a similar source. REE and especially Ni abundances limit the proportion of olivine that is permitted in the residue.
