THE EFFECTIVENESS OF GEOCHEMICAL DATA PROCESSING IN THE MIDDLE OF INNER MONGOLIA BY UNIVERSAL-KRIGING METHOD

Wang Zhenmin Zhang Qingzhou Li Boyang The Tenth Institute of geology and mineral Exploration and Development,Chifeng,Inner Mongolia,024005,China  
Contrasting Probability Statistics analysis method,The paper introduced the principle,method,and characteristics of Universal-kriging method in geochemical data processing.Taking the element Cu of the middle of Inner Mongolia as exampal,The paper extracted Cu geochemical anomaly by Probability Statistics analysis(PS-anomoly),and residual anomaly by Universal-kriging method(UK-anomaly).Based the geology character,Contrasting and analyzing PS-anomaly and UK-anomaly,The result shows PS-anomaly is strong for expression high background geochemical anomaly,and have good relations with Au,Cu,polymetallic ore and so on,but the PS-anomaly is large area,and the large area is not good for finding deposit-location.Compared PS –anomaly,The UK-anomaly is short interference by background,and independence each other,and had good relations with mineral sites of Au,Cu,polymetallic ore,etc..So,the UK-anomaly is good for ore prospecting work.
