摘　　要：迄今为止,铊成矿仅见我国,故研究铊成矿我国应是首开先河。从铊矿床成矿作用研究铊矿床地质地球化学特点,其目的在于强调从生物成矿角度研究微古生物在新陈代谢过程中吸收富集铊成矿和生物残骸积累铊成矿。进而从本质上认识铊在成矿演化过程中地质地球化学和生物化学等多种因素相互作用的特殊成矿机制。Up to now, the T1 deposit has been found uniquely in China, so this project is the first case in the world to study the mineralization of T1 deposit. The characteristics of geology and geochemistry of T1 deposit are viewed in the light of T1 metallization. As the major concern of this paper, the importance of T1 bio mineralization, such as the micro-paleo-organism absorbed and enriched T1 to form ores during the process of metabolism and the biological remains were accumulated to form deposit, is emphasized. In one word, T1 metallization holds the key to understanding of special mechanism that govern the interaction of geology, geochemistry and biochemistry, etc. during metallogenic evolution.
