A study viewed from the clay body: the existence form of the middle and late Jomon pottery type, and each network system

本研究采用体视显微镜和放大镜的简易方法，对中晚期绳纹陶陶土中的粗颗粒进行了观察。从那里我掌握了每个站点的趋势，并对结果进行了比较。其中一个观点是，粘土体中的粗颗粒成分与遗址周围的地质特征是否匹配，从而揭示了每个遗址都存在许多与地质特征不匹配的陶器。从这些观察结果可以看出，陶器类型是通过一个复杂的局部网络系统出现的。

In this study observed coarse particles in the clay body of the middle and late Jomon pottery, by the simple method of using a stereo microscope and a loupe. And There from I grasped the tendency of each site, and compared the outcomes. One of the points of view was whether the composition of coarse particle in the clay body matched with neighborhoods of the site geologically.As a result, the presence of many cases of pottery that is not match the geological features were revealed at each site. From these observation outcomes, it was revealed that the "pottery type" has appeared through a complicated local network system.
