The Lord Howe seamount chain on the western margin of Zealandia some 580 km off the east coast of Australia provides a suitable habitat for the growth of the southernmost coral reefs in the Pacific Ocean. The shelves around Middleton Reef, Lord Howe Island and Balls Pyramid represent carbonate depositional environments where calcareous microfossils are common and generally well preserved. While many of the organisms were originally carried to the islands by an offshoot from the East Australian Current, thus having many species in common with eastern Australia, the islands also exhibit a number...
Lord Howe Island and Balls Pyramid are located at the latitudinal limit of coral reef formation in the Tasman Sea, with the fringing reef on the western margin of Lord Howe Island considered to be the southernmost coral reef in the Pacific. An extensive submerged fossil reef occurs on the shelf around Lord Howe Island. Mapping of the shelf surrounding Balls Pyramid, 24 km south of Lord Howe Island, has revealed a comparable submerged mesophotic reef system in 30–50 m water depth supporting scattered live coral colonies. Radiocarbon dating of coral extracted from limestone cores on the fossil...
With COP15 underway, these extinction-defying species prove that conservation projects can really work.
The Lord Howe Volcanic Complex (LHVC) is part of a seamount chain associated with the detached continental crust of Zealandia. We present petrographic and geochemical data for the LHVC, including the first reported data for Balls Pyramid and the first trace element data for Lord Howe Island, clarifying the tectonic affiliation and general mantle source characteristics. Classification and discrimination diagrams based on concentrations and ratios of immobile elements, such as rare earth and high field strength elements, Th, Ti, Y, and Mg, show the LHVC comprises transitional to alkali basalts a...
