Geophysical Exploration Methods In The Exploration Of Chromite In Mongolian Research And Application

Geophysical exploration is different between the difference of rock and soil physical propertiesfor material foundation, using the physics principle, through the observation and study of thegeophysical field the time and space distribution rule to a new solution to a geological problem,geophysical exploration are many methods including gravity prospecting, magnetic prospectingand electrical prospecting, seismic exploration, radioactive exploration and geothermalexploration. Based on the research of our country chromite geophysical prospecting, and findsthat the extreme lack the resources, we need to constantly upgrade to reduce the shortage ofnatural resources, in order to guarantee the sustainable development of the resources, we need toput forward some countermeasures, especially in search of chromite aspects.Since the1980s, many metal mineral exploration work rising trend promoted the developmentof various exploration method, with the surface mines with shallow ore decrease, prospectingdifficulty increase, especially formation exposed poor areas, the role of the geophysicalexploration method will be more and more important. Cover thickness, burial depth, complicatedgeological conditions in the seeking for concealed mineral resources, mineral resourcesexploration field at home and abroad are facing important problem. Using the integratedgeophysical exploration methods for fast evaluation is one of the ways to more effective. Theintegrated geophysical exploration methods in the cover thickness, burial depth, complexgeological condition in the process of seeking for concealed ore body has always been playing animportant role, is fast, economic, accurate advantages. Geophysical methods varied, each kind ofgeophysical method has strict requirements for the application condition and scope.Becausegeological, geophysical characteristics and natural geographical conditions vary from place toplace, that affect the geophysical method’s effection.According to the differences between theneeds of exploration of ore deposit types and rock physical property we should usedcomprehensively several geophysical prospecting methods, in order to get better results.we alsoneed get closed with the Geology...
