NEWSBREAKERSChile and Argentina on high alertThe increasingly active Copahue volcano, on the border between Chile and Argentina, has raised concerns of an imminent eruption. A mandatory evacuation order covering a 25 kilometre radius had been ignored by many locals who do not want to leave their livestock. Recent seismicity and deformation data suggested the rise of a magmatic body to shallow depths. Australian opal points to MarsOrganic rich anoxic conditions on the seafloor covering central Australia during the lower Cretaceous produced a sedimentary deposit rich in ferrous iron, pyrite and other minerals that set the scene for the formation of opal. A prolonged period of acidic oxidative weathering developed over the vast area as uplift and erosion began to expose the rocks. Such regional acidic weathering is rare on Earth but acidic oxidative weathering has been documented at the surface of Mars. This suggests the Australian opal fields could be the best regional terrestrial analogue for the surface of the red planet. FROM THE DIVISIONS

Biennial Conference of the Specialist Group in Geochemistry, Mineralogy and Petrology: Rocks, Reef and Rainforest (R3)Following the format of the successful Kangaroo Island (2009) and Murramarang (2011) SGGMP conferences, this Gordon-style conference held in tropical North Queensland
will combine oral and poster presentations, field trips, and a packed social program.

Alien more spin than spinelComputer modelling has been used to show that magnesium-rich spinel and olivine found in the central peaks of lunar craters may not be from lunar sources. Since their discovery it has been assumed these minerals were forced to the surface of the crater by the asteroid or meteorite impact event because high speed impacts would vaporise 'alien' minerals in the asteroid or meteorite. The new simulations show asteroids are capable of producing significant craters at lower impact speeds, giving the minerals they contain a greater chance of surviving the impact. Weaning age fossilisedAustralian and US researchers have shown barium in tooth enamel records the duration of breastfeeding in human children and have used these findings to determine how old one Neanderthal child was when weaned. The Neanderthal child's molar barium levels indicate it was exclusively breastfed for at least seven months and fully weaned at 1.2 years of age. ON THE WEBSlow sliding slopSeveral homes in California have been destroyed and many more are in danger of destruction as excess ground water causes the local ground surface to move down slope up to two metres a day in some places.
Lunar flashA space rock, estimated to weigh 40-kilograms, recently hit the Moon at about 90,000 kilometres per hour, creating a flash of light so bright that anyone looking at the Moon at the moment of impact could have seen it without a telescope. Island amphibian liked a fightA new amphibian that lived 130 million year ago has been discovered on the Isle of Wight. The small amphibian, found as numerous but isolated bones, shows damage to the jaw bones consistent with fighting with rivals. Chisel-like teeth indicate it was a predator but other aspects of the skeleton suggest it was also adapted to burrowing. IN THE MEDIADawn bird throws light on ArchaeopteryxA complete skeleton of a new paravian theropod dinosaur from the Middle-Late Jurassic Tiaojishan Formation in China has enabled a comprehensive phylogenetic analysis of basal bird-like fossils that places Archaeopteryx back as the ancestor of birds. The new dinosaur, Aurornis xui, is also considered a basal bird even more primitive than Archaeopteryx. FUTUREVOLC opens for businessFUTUREVOLC is a monitoring system and network funded by the European Commission. It aims to engage in long-term monitoring in geologically active regions of Europe prone to natural hazards and is making great progress in Iceland. A description of present-day in-situ monitoring networks in Iceland and available results is now on-line and plans are underway to put in place systems to monitor active volcanoes in Iceland located under ice caps.
