| 中文摘要:退火成矿环境研究是近年来矿床学发展的新方向之一，丰富多彩的退火结构、构造现象在越来越多的热液矿床中被发现，足以说明退火环境在热液矿床成矿过程中的重要性，然而这些理论研究以往并未得到实验的验证。本项目通过退火模拟实验，成功地再现了凡口矿区的矿石和围岩的退火结构、构造和独特的球状闪锌矿晶粒的重结晶加大现象，证实了退火重结晶作用是凡口特大型铅锌矿床成矿作用的一个重要方面，开拓了矿床学研究的新领域。 |

| Abstract: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. |
