日本列岛处于亚洲大陆与太平洋之间,其地体的形成和构造体系,受亚洲大陆和太平洋的严重影响,因而是极其复杂的。现在加以论述。一、日本列岛的形成日本列岛古老地层很少,主要属古生代志留纪以后的地层。其形成的过程主要是由地槽发育经过海西运动(秋吉,佐川运动)、中生代运动(日高运动)和第三纪阿尔卑 The Japanese archipelago lies between the Asian continent and the Pacific Ocean. The formation and tectonic system of the continent is severely affected by the continents of Asia and the Pacific and is therefore extremely complex. Now to be discussed.

Its formation process is mainly developed by the trough development Hercynian movements (Aki, Sagawa movement), Mesozoic (Japanese high movement) and the Tertiary Alpine
