“…Sub-samples 1, 2, 4 and 4 A were used for the determination of metallic Fe and sulfide Fe by potassium cuprochloride solution. The details of the analytical method are described elsewhere (Hughes and Hannaker, 1977). In the case of Yamato (I), a diogenite fragment separated from the main part was also analysed by wet chemical methods.…”

“…For Fe" the copper sulfate procedure described by Habashy (1961) and the method of Hughes and Hannaker (1978) were used. After dissolution of the sample, Ca, Ma, K, and Na were determined by atomic absorption spectroscopy (AAS) (Ward et al, 1969).…”

“…Chemical analyses were carried out on pulverized material from three fragments of Jolomba weighing 2.4, 2.8 and 3.8 g. Material from the first two fragments contained small fractions of the fusion crust and was used for partial analysis only (Table 2, columns 2 and 3). A complete analysis was performed on the third fragment, essentially following the procedures described by Shima (1974), slightly modified for the determination of alkalies and phosphorous (see Hughes and Hannaker, 1978).…”

Abstract— Accompanied by loud thunder at about 1.30 pm (local time) on 3 February 1974, a single stone weighing approx. 480 g was seen to fall and was recovered near the Jolomba village, Huambo District, Angola. The stone is strongly brecciated, has dark‐greyish angular fragments within a lighter matrix and does not exhibit any chondritic textures. Jolomba consists of olivine (Fa 31), orthopyroxene (Fs 25), sodic plagioclase (An 11), sulphides (troilite), very scarce nickel‐iron (Ni up to 56%), oxides (chromite and ilmenite) and apatite. Pervasive fracturing of silicates suggests that Jolomba suffered strong brecciation and partial recrystallization. Mineralogy and bulk chemical analysis indicate that Jolomba belongs to the LL group of chondrites (amphoterites). Uniform olivine and pyroxene composition, well‐crystallized plagioclase and textural features in general indicate that Jolomba belongs to the petrologic type 6.
