Dendrogeochemical Study of a Copper Deposit in Black Springs, Australia

The Bushranger Copper project is a known porphyry-style copper deposit located roughly 150 km west of Sydney in New South Wales, Australia. Monterey pines (Pinus radiata) growing over the mineralization were cored and their rings were counted. Segments of the core representing growth between 2003 and 2008 were selected, digested in nitric acid, and analyzed via ICP-MS. This time span was selected because there was the least variation in tree ring width among all samples during these years, indicating uniform growth. The relative concentrations of the pathfinder elements Al, Cu, Mo, Pb and Zn were highest in the south-western corner of the area. Based on the data this area is the most prospective area to conduct further exploration efforts.

Japan and China: Bitter Rivals and Close Partners. Asia Policy Brief 2013/03, June 2013

Japan and China trade a lot between each other. Unfortunately, however, they also argue a lot with each other. Since Tokyo’s purchase of three uninhabited Japanese-controlled islets in the East China Sea from their private owner in September 2012, the main subject of dispute has been that of sovereignty over maritime territories. While bilateral trade amounted to an impressive $333 billion in 2012 (slightly less than in 2011, when bilateral trade reached $345 billion), a bilateral territorial dispute over control and sovereignty of what Tokyo calls Senkaku and Beijing calls the Diaoyu Islands will most probably continue to remain at the very top of the agenda of Sino-Japanese relations in the months ahead.
