摘要:
永丰县长田坑滑石矿的评价尝试以滑石矿物含量作为工业指标进行了矿床评价,取得了较好的找矿效果。本文介绍了长田坑滑石矿矿物含量的测定方法,采用电子探针分析求取滑石的换算因数,进而计算矿区滑石矿物的含量并圈连滑石矿体。还探讨了化学分析与X射线衍射分析测定值的相关性,并采用差热分析的测定值对化学分析的换算值进行了验证,显示两值基本吻合。反映了该方法在同类滑石矿勘查评价中具有较好的可操作性。
Abstract:
By investigation and research of seawater intrusion in Daweijia of Dalian city, Zaoyuan of Qinhuangd-ao city and south coast of Laizhou Bay,combing with existing research achievement and methods,this study sum-marized and combed the research status and existing problems and analyzed investgation and research methods of seawater intrusion. Investigation and research work for the past many years in Circum-Bohai-Sea Region cleared up basically the mechanism and dynamic change trend of seawater intrusion of different location and types and provided scientific basis for seawater intrusion prevention.With the deepening of research on seawater intrusion problems,there are still problems discovered in hydrogeologic conditions,hydrodynamic monitoring and eco-envi-ronmental influence of seawater intrusion,and seawater intrusion should continue to strengthen monitoring and re-search. Investigation and research of seawater intrusion is a multidisciplinary integrated technology,including fun-damental research,comprehensive analysis,hydrodynamic monitoring and numerical simulation redearch,etc.Hy-drochemical analysis, isotope tracer technique and laboratory simulation test,etc can be used to reveal the mecha-nism of seawater intrusion and the solute transport law of transition zone . Based on above research, it can make a prediction of sea intrusion and improve prevention awareness.
