综合找矿技术在深部找矿评价中的运用——以河南省嵩县东湾金矿勘查区为例

河南省嵩县东湾金矿勘查区是最近两年熊耳山地区重要的找矿发现之一。矿区位于华北板块南缘马超营断裂带以北的熊耳山隆断与外方山隆断的交接部位。矿体赋存于马超营断裂带上盘近SN向—NNE向的F22断裂带内部,埋藏于地表之下100余m。目前矿区已施工钻孔14个,初步控制一处走向延长1050m,最大倾斜     

The formation and tectonic evolution of Philippine Sea Plate and KPR

The Philippine Sea Plate has an extremely special tectonic background. As an oceanic plate, it is almost entirely surrounded by subduction zones with complex internal tectonic features. On the basis of enormous published literature, this paper offers a comprehensive overview of the tectonic and evolution history of the Philippine Basin and the Kyushu-Palau Ridge (KPR) in the Philippine Sea Plate, and discusses the geological features of KPR. Referring to relevant definitions of various "ridges" stipulated in United Nations Convention on the Law of the Sea, so the KPR is believed to be a remnant arc formed during the opening of the Parece Vela and Shikoku Basins in the Philippine Sea Plate. It is a submarine ridge on oceanic plate rather than a submarine elevation. And thus, it is not a natural component of the Japan continental margin.     

日本震后可能东移4米

英国研究人员以日本地理网大约1200个全球定位系统监测站数据为依据,发现日本可能因11日强烈地震向东移动最多4米。英国地质勘查研究所研究员布赖恩·巴普蒂向英国广播公司记者解释道,日本地处两大板块交界处,一个是太平洋板块,另一个板块则被不少地质学家视为北美大陆板块延续。
