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

本研究采用立体显微镜和放大镜的简单方法，对绳纹中晚期陶器粘土体中的粗粒进行了观察。从那里，我掌握了每个网站的趋势，并比较了结果。其中一个观点是粘土体中粗颗粒的组成是否与遗址的邻域地质匹配。结果，在每个遗址都发现了许多与地质特征不符的陶器。从这些观察结果可以看出，“陶型”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.
