摘　　要：通过对宁波大榭遗址出土的夹砂陶器、夹贝陶盆、烧土块、支脚、结核物等遗物进行检测,对相关遗物进行成分、物相分析以获得基本的材质信息,对部分遗物中的碳酸钙进行了碳、氧同位素的研究以了解其形成过程,帮助判断遗迹成因与遗物所经历的事件,并且辅以锶同位素去判断一些样品的海相或陆相来源。分析结果表明,一些非海相、但与海水关系密切的方解石质结核物的生成温度在38℃左右,或许是在晾晒过程中,土壤中原本的钙质与盐泥或盐水中的钙质混合并析出,最终形成了这种遗迹。此外,陶盆内壁的风化情况以及其中贝壳羼和料的碳、氧同位素也显示其可能用来煮水,同时观察到一些红烧土块外部风化酥粉严重,可能也曾在加热后被投入盐水中辅助升温。综上所述,大榭遗址的遗迹遗物与制盐密切相关,且当地的制盐产业可能采用了晒煮结合的工艺。We studied the remains of the pottery tempered with sand and shell,burnt clay blocks,briquetages and calcareous concretion excavated from the Daxie site in Ningbo,carrying out compositional and phase analyses of them to obtain basic material information.Carbon and oxygen isotope studies were carried out on some of the calcium carbonate in the relics to understand their formation,to help find out the cause of formation of the remains and the events through which they were formed,and supplemented with strontium isotopes to determine the marine or terrestrial origin of some samples.Based on the results of our study,we found that some calcareous concretions,which were nonmarine but closely associated with seawater,were produced at a temperature of around 38°C.Perhaps the calcium in the soil mixed with those precipitated from the salt mud or brine during the drying process,eventually forming such remains.In addition,the weathering of the inner wall of the pots and the carbon and oxygen isotopes of the tempered shell material within them also suggest that they might be used to boil water.In addition,some of the burnt clay pieces were observed to be heavily weathered and powdered outside,they may have been put into brine to heat it.In summary,the remains from the Daxie site were closely associated with salt production,and the local salt industry might use the method of both solarevaporation and manual heating.
