Trace-element characteristics of east–west mantle geochemical hemispheres

Recent statistical analyses on the isotopic compositions of oceanic, arc, and continental basalts have revealed that the Earth's mantle is broadly divided into eastern and western hemispheres. The present study aimed to characterize the isotopically defined east–west geochemical hemispheres using trace-element concentrations. Basalt data with Rb, Sr, Nd, Sm, Pb, Th, and U in addition to the isotopic ratios ⁸⁷Sr/⁸⁶Sr, ¹⁴³Nd/¹⁴⁴Nd, ²⁰⁶Pb/²⁰⁴Pb, ²⁰⁷Pb/²⁰⁴Pb, and ²⁰⁸Pb/²⁰⁴Pb were selected mostly from the GEOROC and PetDB databases. A total of 4787 samples were used to investigate the global geochemical variations. The results show that the wide trace-element variations are broadly explained by the melting of melt-metasomatized and fluid-metasomatized mantle sources. The larger amount of the fluid component derived from subducted plates in the eastern hemisphere than that in the western hemisphere is inferred from the basalts. These characteristics support the hypothesis that focused subduction towards the supercontinent created the mantle geochemical hemispheres.

The Necessity for Multi-disciplinary Research: Ralph Jacobi's Institute of Freshwater Studies

In spite of many proposals, Australia has no national freshwater research centre. Thus the passing in the Senate of Ralph Jacobi's private member's bill for an Institute of Freshwater Studies in 1982 was unusual. His driving force was the need to overcome State boundaries and for research to inform policy and management of water resources. It gained widespread support, and not just from the parliamentary Labor Party, but was strongly opposed by the Fraser government, State and federal water bureaucracies, and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The election of 1983 prevented further discussion in parliament, but the proposal was part of the Labor Party platform taken to the election. An Interim Council set up to investigate whether or not such an institute should be established, but with narrow terms of reference very different from those in Jacobi's bill, sided with the large water bureaucracies and CSIRO, in spite of majority support for an institute. An institute was rejected and the government accepted the recommendation. Jacobi's proposal failed primarily because of a fear of independent advice by many in the bureaucracies, a potential loss of power and influence, and inter-governmental rivalries. The status quo remained; the bigger picture is still unseen.

A new species of Eomeropidae (Insecta: Mecoptera) from the Middle Jurassic of China

The Eomeropidae is a species-poor family with only 11 known fossil species from the Early Jurassic to Palaeogene. A new species of fossil eomeropid, Tsuchingothauma gongi sp. nov., is described based on a well-preserved wing from the Middle Jurassic Daohugou deposits of Inner Mongolia, China. Our new species is distinguished from the type species T. shihi mainly in having very numerous crossveins and cells; more longitudinal veins: 13 and 11 terminal branches in radial sector and medial field, CuA with 3 terminal branches and A with 7 terminal branches.
