摘　　要：本文以铜陵地区发现的响石为研究对象,通过野外地质观察、结合室内光薄片及地球化学测试分析等,对响石形成的地质背景、地貌特征、气候条件和沉积环境等进行了分析,认为丰富的物质来源、松散的运移通道、干湿交互的气候以及特殊的胶体凝聚沉淀环境是铜陵响石形成的重要条件,代表了一个比较复杂的化学沉淀过程。Through geological observation in the field,microscopic observation of polished and thin sections,and geochemical analysis,this paper makes a detailed description and study on the“sound stone”found in the Tongling area from such perspectives as:the features of the geological profile targeting the“sound stone”;the occurrence location,morphological structure,material composition of the outer shell and inner core,and petrochemical characteristics of the“sound stone”.The geological setting,geomorphic features,climatic and sedimentary conditions are analyzed for the“sound stone”.It is suggested that the abundant material sources,loose migration channels,dry-wet climate interaction and special colloid condensation and precipitation environment are important to the formation of the“sound stone”in Tongling,which involves a relatively complex chemical precipitation process.We hope that this study can resolve some doubts concerning the“sound stone”and help to understand“sound stones”in other places.
