Phase Analysis Method Is Applied To The Sample Analysis Of Geochemical Anomalies In Heilongjiang Province

Geochemical exploration is one of the primary means of geologicalexploration. Usually geochemical prospecting work is based on analysisof the full amount of the element-based. With the development ofanalytical techniques, the sensitivity of the analysis of each elementis increased. At the same time have also found a large number ofgeochemical anomalies. The key issues of the geological prospecting workis the information characteristics of the geochemical anomalies,excluding the exception of the non-mining and rapid screening of minecaused the exception.The application of phase analysis method to evaluatethe geochemical anomaly is a good distinction between the mineralization,and non-mine of anomalies. Fast, accurate, trace, multi-metal elements,phase analysis techniques, has been the research topics at the forefrontof the world to academia for chemical analysis of workers. Chinese Academyof Geological Sciences, metallurgical industry, carried out in the1990strace phase analysis method. It is based on the chemical phase analysisof the technology as the basic means. It studies the mode of occurrenceof elements in rocks, soil, stream sediment. It will be the phase analysisof trace. And the analysis of technical data used to study the evaluationof the geochemical anomalies and look for deep concealed orebody. Theyhave been in the Shaanxi, Xinjiang, Inner Mongolia, Liaoning, applicationof this technology. They have been evaluated in gold, copper, lead, zincpolymetallic anomaly area. They also provide an important basis for thediscovery of non-ferrous metal deposits.All prospecting methods do not have broad applicability. Different minerals, different surface landscape, different stages of explorationhave a certain scope of application. In different climatic regions, theamount of each phase the existence of matter is also different. Therefore,for the special landscape geochemical conditions in HeilongjiangProvince, selecting some key metal elements (gold, silver, copper, lead,zinc, molybdenum), according to the form of existence of the elementsin the sample, according to the needs assessment element of the exceptionto the design pointsphase process, has established the phase analysismethodology and technology program of exploration of some key metalelements in the abnormal samples Heilongjiang Province. And twogeochemical anomalies in Heilongjiang Province, validated test. Thesamples were phase analysis and evaluation. Results may provide a moreaccurate mine of anomalies, reduce the blindness of GeochemicalExploration, miniaturize the geochemical anomaly "target".Proposing andestablishing the phase analysis methodology and technology programthrough the study the characteristics of Heilongjiang Province,whichcan screen and evaluate quickly to large number of geochemical anomalies,and also can provide technical services to accelerate the pace ofgeochemical exploration.
