U/Th-rich bitumen in Archean granites and Palaeoproterozoic metasediments, Rum Jungle Mineral Field, Australia: implications for mineralizing fluids

Uranium/thorium (U/Th)‐rich bitumen has been discovered within both Palaeoproterozoic black pelites and the Archean granitic basement of the Rum Jungle Mineral Field, Northern Territory, Australia. Granite‐hosted bitumen occurs as small (up to 400‐µm diameter) discrete individual nodules, which exhibit many morphological similarities to those observed in Phanerozoic siliciclastic rocks. Thorium, the dominant radioelement, occurs primarily as a hydrated Th–Y–Si–P phase. Uranium‐rich inclusions are rare, and correspond to a hydrated U–Th–Y–Si–P phase, identified as coffinite–thorogummite. Metasediment‐hosted bitumen is more variable in morphology, occurring as massive (<2 cm in width) veins that cross‐cut all foliations, as discrete individual nodules or as elongate seams (up to 500 µm in length), interpreted to represent a series of coalesced individual nodules. In all examples, uranium, the dominant radioelement in the metasediment‐hosted bitumen, is present as Th‐poor uraninite, with variable Y₂O₃ contents (up to 3.21 wt.%). Raman investigation of all types of bitumen indicates that it is a poorly organized carbonaceous matter, which has not been subjected to metamorphism. Consequently, a post‐metamorphic timing for hydrocarbon emplacement can be inferred and a magmatic origin can be precluded. Potential source rocks for the bitumen are black shales of the Whites Formation (up to 8 wt.% total organic carbon (TOC)) and the Koolpin Formation (approximately 13 wt.% TOC). Post‐metamorphic sericitization of rocks within the Whites Formation is accompanied by a near‐complete removal of organic matter. Alteration was possibly the catalyst for hydrocarbon generation. The Th–Y–Si–P phase within the granite‐hosted nodules is interpreted to be the result of the alteration of antecedent monazite. During this alteration, U, LREE and P were fractionated and removed, while Th, Y and Si remained immobile, and recombined to form a hydrated Th–Y–Si phase. This pervasive alteration within the basement U/Th‐rich granites is proposed as a genetic model for the formation of uranium deposits in the Rum Jungle Mineral Field and possibly unconformity associated uranium deposits on a global scale.     

The Life of the Law in the Islamic Republic of Iran

Beyond the esoteric deliberations of Islamic jurists and their exegesis of criminal and private law doctrines, Iranian law lives a life of its own. It is a life of routine practices of judges, court clerks, lawyers and clients, each of whom is striving to turn the law to their own advantage. It is also a life of contested legality, a relentless struggle over the right to determine the law in a juridical field which is infused with strife and hostility. These conflicts are reproduced daily as two competing conceptions of law, and their corresponding perceptions of legality clash in pursuit of justice. The Iranian judiciary’s concept of law, its reconstruction of Islamic jurisprudence and methods of dispensing justice, which on the surface are reminiscent of Max Weber’s “qādi-justice,” collide with the legal profession’s formal rational understanding thereof. However, Iranian judges are not Weberian qādis, and the legal profession is not a homogenous group of attorneys driven by a collective commitment to the rule of law. To understand their conflict, we need to explore the mundane workings of the legal system in the context of the transformation of Iranian society and the unresolved disputes over the direction of its modernity.

Stable nitrogen isotopic examination of Norse sites in the Western settlement of Greenland

To continue to explore the impact of past human activity on the stable nitrogen isotope ratios of modern vegetation, we have measured the δ¹⁵N values of plants now growing on several ancient farmsteads in the Western Settlement of Norse Greenland. Although this new test area is some 400 km north and in a different ecoregion from the previous study area, the same isotopic effect was observed. A clear isotopic signature was found on the ancient farms which could be directly correlated to past activity areas; in particular, the infields. Further, the magnitude of the δ¹⁵N values was found to be similar between study areas, indicating the same interpretative framework can be applied in widely separate geographic regions. A first test of different plant species showed that although the magnitude differed greatly the same basic information was found for functionally different plants. These observations provide additional information to aid in future archaeological application of this newly observed phenomenon.     

'An Unbelievable Academic and Personal Experience': Issues around teaching undergraduate field courses in Africa

This paper explores the teaching of geography field courses in Africa for UK university undergraduates. Using largely qualitative feedback, the experiences of students, staff and local communities involved in field courses to Kenya, Zimbabwe and The Gambia are evaluated. Benefits and disbenefits of these field courses to the participating students, the local community and teaching staff are scrutinised. The paper concludes that such field courses to 'exotic' destinations are an effective means to student recruitment and certainly achieve their aims while providing meaningful teaching and learning experiences. Furthermore, the analysis shows that field courses to 'poor' destinations in sub-Saharan Africa can avoid dangers of 'development tourism' if conducted with ethical sensitivity.
