| Abstract: | Exploration geochemistry has made great successes in the discovery of mineral deposits which are difficult to be recognized. Although splendid achievements have been made, exploration geochemistry is facing new difficult-to-be-recognized types of mineral deposits such as sandstone-type uranium, PGE hosted in black shales, rare and dispersed elements and gold associated with oil basin. This paper briefly describes exploration geochemistry for these 4 new difficult-to-be-recognized types of mineral deposits. Deep-penetrating geochemical methods were used in delineation of sandstone-type uranium deposits in Turpan-Hami Basin, Xinjiang. Large-sized gold anomaly was delineated in Shangli oil field, Shangdong, which probably indicates gold mineralization associated with the oil field. The distribution of Pt in China shows that PGE deposits are likely to be found in black shale sequences of southwestern China. Geochemical mapping with over 70 elements will contribute to the exploration of rare and dispersed elements. |
