成矿作用爆发异常及巨量金属堆积

在对华北地台北缘和南岭两金属成矿省代表性矿田的等级体制成矿研究的基础上,应用矿床储量相对丰度及其形成时限推论巨量金属堆积速率,探讨了大气变态和构造圈热侵蚀等成矿热事件在地质历史上出现频率及其激发巨量金属堆积的成矿规律,为爆发异常成矿提出新思路,据此,提出鞍（山）－本（溪）铁建造成矿区的成矿远景还将有扩大的可能,湘桂粤拗陷和粤北隆起两成矿区的钨锡成矿远景也将有望再扩大。     

Geoelectric section of the tectonosphere in the junction zone between the Sea of Japan depression and its continental framing

New data on the deep geoelectric structure of the tectonosphere in the junction zone between the Sea of Japan and continental structures are presented. The geolelectric section was modeled using unique data on the monitoring of the electric field variations in the JASC submarine trans-Japan communication cable and segments of land cables in the Primorye region. The monitoring was accompanied by recording of the geomagnetic field at the VLA, KHB, MMB observatories and PPI stationary site. In addition, magnetotelluric data from 80 field MTS sites in the territory of the Hankai Massif and Sikhote-Alin fold belt were used.
