日本地质学家曾用“绿色凝灰岩”的绰号来形容日本内陆带特有的中新世火山杂岩。然而，现在在日本被称为绿色凝灰岩地区的地区如图1所示被扩大。该地区是日本最重要的金属和石油开采省份之一。本文概述了该地区的地质历史，并着重介绍了日本东北部地区，特别是秋田地区。在秋田地区，中新世沉积在地层上被划分为七个阶段，并大致列举如下表所示：
The nickname" Green Tuff" had been used by Japanese geologists for the Miocene volcanic complex which is characteristic to the inner zone of Japan. However, the area now called the Green Tuff region in Japan is enlarged as shown in Fig. 1. This area is one of the most important mining provinces of Japan in both of metal and oil. In this article, outline of the geological history in this region is explained, attaching importance to northeastern Japan, especially to the Akita district. In the Akita district, the Miocene sediments are stratigraphically divided into seven stages, and they are roughly enumerated as shown in the following table:
