THE XIAOJIAPOIGOU BORON DEPOSIT IN LIAONING PROVINCE: Geological features and prospecting measures in the old orefield

Based on the analysis of geochemistry, geologic structure, magmatic characters, ground magnetic signature and stream sediment anomaly of the Xiaojiapigou boron deposit in Liaoning Province, the geological features related to the exploration (or reserves increasing) are studied in detail. A procedure on the prospecting in the old orefield is summed up, i.e. geochemical survey to determine direction, geophysical survey to position, geological survey to detect the nature, and engineering to find out the amounts.
