Annealing-Simulated Experiments on Lead-Zinc Ores and Wallrocks from Fankou Lead-Zinc Deposits
凡口铅锌矿床矿石与围岩退火模拟实验研究

Researches on annealing metallogenetic setting seen to be a new developing orientation in the study of mineral deposits in recent years.Varied and colourful phenomena of annealing texture and structure are found in more and more hydrothermal deposits,indicating that annealing setting play an important role in the metallogenetic process of hydrothermal deposits. However, these studies hove not been proved by the experiments.Based on annealing_simulated experiments, the authors made a reappearance of annealing texture and structure of lead-zinc ores and wallrocks of the Fankou lead-zinc deposits in the laboratory, especially a reappearance of the spherical sphalerite of recrystallized enlarging phenomena.The results show verify that annealing recrystallization is an important aspect of metallogenetic process in the Fankou lead-zinc deposits,thus developing a new researching domain for ore deposits.
