Xiangquan: The World’s first reported sediment-hosted thallium-only deposit, northeastern margin of the Yangtze Block, eastern China
Thallium is a dispersed element that seldom occurs as independent minerals. Consequently it is difficult to form a discrete thallium mineral deposit. This paper reports the first example of a thallium-only ore deposit discovered in the northeast margin of the Yangtze block, eastern China. Hydrothermal enrichment on the ancient sea floor and hydrothermal reworking during the Yanshanian orogeny are the two important metallogenic events that led to the formation of the thallium deposit.
