With the inductively coupled plasma atomic emission spectrometry, the HF-HNO3-HClO4-H3PO4 dissolving samples were employed to determine B in carbonate formations. The method lies in adding an appropriate amount of H3PO4 in the sample dissolution system to avoid the loss of the volatile elements B and testing the optimum amount of H3PO4. The accuracy and precision of the method are demonstrated by analyzing the National Standard Reference Materials, and it is proved that the precision (RSD) is less than 6.44%, and the RE (ΔlgC) is less than 0.087. The method can also determine such elements as Be, Ba, Cr, Cu, Co, Ni, Pb, Mo, V, Mn, Li, Zn and Ga at the same time. The method can determine B and various other elements in soil, rock and stream sedi-ment samples. The method was used to determine B, Co, Ni, Cu, Zn, Pb and Ba in carbonate formation of Karaqi area in southeast Tianshan Mountains, and its geological significance was discussed in this paper.

The analytical method matching scheme of 19 elements in geochemical samples in Karaqi area of Southwest Tianshan Mountains was optimized by changing the sample dissolving method, improving the analytical method and considering the characteristics of the sample. The quality management system comprising man, machine, material, method, measurement and surroundings was established and improved. The laboratory information management system consisting of seven modules (LIMS) responsible for the quality management information and standardization was also developed and constructed. The scientific and perfect 1:50000 regional geological and mineral survey sample quality monitoring system was constructed by internal and external controlling methods for accuracy, precision, repeatability test, abnormal point and external monitoring. By adopting various means, establishing foundation of information courses and utilizing advanced monitoring system graphic display, the authors have supplied accurate geological-geochemical information for geochemical prospecting and basic research in Karaqi area of Southwest Tianshan Mountains.
