FEASIBLE STUDY ON THE INTEGRATION SYSTEM FOR THE SPACE MONITORING OF MAJOR EARTHQUAKES AND VOLCANOES IN TERRESTRIAL LAND

With the rapid development of space technology, earth observation technology and sky observatory technolo-gy, they have played a more and more important part in monitoring and predicting of earthquakes and volcanoes in the terres-trial land. In recent years, the related agencies have done the experiments and researches on monitoring and predicting ofearthquakes and volcanoes in the forewarning period by means of many approaches, such as satellite thermal infrared re-mote sensing (TIRS), Global Positioning System (GPS), differential interferometric synthesis aperture radar (D-INSAR),astronomical time-latitude residual anomaly, and Geographic Information Systems (GIS), etc. A quite large number of re-search foundation has been built in the fundamental theories and application methods. The experiments and researcheshave shown that these technology is efficient methods for high frequency crust movement. If the existed separate scientificforces and results are possibly assembled together to form a more complete integration monitoring system with the combina-tion of space, sky observation, ground, deep geology and macro anomaly, it will come into a new stage of monitoring andpredicting of earthquakes and volcanic eruptions.     

广西凌云县逻楼金矿生产性堆浸试验研究

本文介绍了广西凌云县逻楼金矿微细粒浸染型金氧化矿石的生产性堆浸试验。试验方法采用氰化法堆浸,其工艺流程是:原矿石—二段破碎—筑堆—洗矿—喷淋浸出—炭吸附—解吸—电解—熔炼。试验结果:入选矿石量3231t,矿石品位Au2.56g/t,浸出时间48天,尾渣品位Au0.69g/t,金浸出率72.86％,回收率70.25％,回收黄金5735.24克。金生产单位成本为39.67元/克,获纯利润4.7万元,取得了较好的经济效益。     

我国南方一些金银矿床和锡—银多金属矿床中的银黝铜矿及其标型意义

本文主要通过我国南方一些金银矿床和锡—银多金属矿床中的银黝铜矿的化学成分标型特征分析对比,结合其光性、物理性质及与其它矿物连生组合特征,探讨了不同矿床(矿田)银黝铜矿的成因标型意义。并指出银黝铜矿可作为广西找银矿的标型矿物是具有现实意义。     

梦想晚白垩纪公园

晚白垩纪是地质学的一个新名词,距今大约五千万至七千万年. 轻轻的,我像往常一样走进这片熟悉的土地.如果没有人告诉我,脚下这块偌大的冲击盆地在白垩纪早期竟是一个碧波荡漾的湖泊,很难想象它有多么的古老.     

板状铀矿床的新模式

本文概述了板状铀矿床的共性特征，初步明确了板状铀矿床的概念及归属划分。以典型矿床为例，着重从水文地质角度，利用地下水流动机制和密度分层流体界面理论提出了板状铀矿床的成矿模式。较全面地阐述了地下水排泄体系中成岩－成矿的时间序列和空间定位。     

微波Ⅲ型爆发与日冕物质抛射的统计分析

对国家天文台2.6～3.8GHz频谱仪在第23太阳活动周上升段(1996～1998)记录到的Ⅲ型爆发,与日冕物质抛射(CME)作了统计分析。发现微波Ⅲ型爆发可能是CME的先兆现象,并讨论了它们的辐射机制。
