摘　　要：通过对江苏东海区域成矿地质条件以及含晶石英脉成群成带分布规律的研究,得出以下结论:①该区水晶矿床为原生矿、砂矿两种类型;②水晶原生矿形成于前震旦纪以后到白垩纪以前的高、中温热液期;③矿体具分布广、规模小、分布散等特点;④东海水晶储量丰富、品位极高、埋藏浅,具有很好的开发利用前景。研究成果旨在为该区域水晶矿进一步的勘探、开发及利用提供重要依据。The geological conditions of Donghai in Jiangsu, as well as the distributed rule of the vein of quartz, were analyzed. It can be concluded that： First, primary deposit and placer deposit are two main deposits in this origin; Second, the primary deposit formed at hydrothennal stage and mesothennal stage between Presinian and Cretaceous; Third, the feature of ore body is wide and scattered on distributing, small on scale; Four, the storage capacity of the crystal is very abundant, its quality is fine, depth of burial is shallow. So it has a good exploit foreground. The results give important references to the further detailed exploration.
