Factor score model method and its application in regional geochemical exploration;

Up to 2000, regional geochemical exploration in rock areas of Xinjiang had nearly been completed with the covering area of 857 400 km2.

Regional geochemical exploration for platinum and palladium;

With regards to the development trend of geochemical exploration, this paper discusses its direction, and points out the geochemical exploration that may play important role in mineral exploration, environment evaluation, ecological study and farming_forest_herd industries and other fields else.

It is the main purpose of this paper that the superiority of exploration geochemistry and regional geochemical data can be successfully applied to environmental and agricultural fields so as to play their guiding role in comprehensive ecological improvement and agricu.

As a result, a series of important advances and achievements were made, and the development pattern of exploration geochemistry in the new era which lays equal st.

With 70 year development, exploration geochemistry has expanded its scope from a tactical mineral exploration tool into a strategic methodology and from an experience technology into a science.

A review was made in the paper on the analytical technique in determination of geochemical exploration samples since 1950s, with major achievements in multi-elements analytical systems, development of new analytical instruments and technology, personnel training and the preparation for Laboratory Metrology Accreditation in the Central Laboratory of IGGE introduced.

Summing up the basic theories of geochemical exploration has revealed some problems occurring at present exploration of geochemistry in development of social-economy.
