最近的工作已经很好地确定了日本花岗岩类矿床的特征，主要是白垩纪和中新世时代。在朝鲜半岛，侏罗纪 Daebo 和白垩纪 Bulgugsa 花岗岩活动得到确认，并且与这些活动成因相关地形成了 Au-Ag、W-Mo-Bi、Cu-Zn-Pb、Fe (-Cu) 和 F 矿床。除了 K-Ar 年龄测定数据外，一些地质证据表明朝鲜主要的 W-Mo-Bi、Cu-Zn-Pb 和 F 矿化发生在白垩纪。这一初步结论使得日本和韩国白垩纪成矿特征的关联成为可能。两国Cu和Zn-Pb矿床的分布格局似乎与目前的侵蚀程度有关，即Cu与深成活动有关，而Zn-Pb与浅成到喷发活动有关。主要萤石矿床往往形成于浅层环境中，可能与地面火山活动有关。两国之间未能获得W-Mo矿化的明确相关性。为了获得白垩纪日本西南岛弧的准确位置，尝试重建日本西南岛弧相对于朝鲜半岛的位置（图4）。由于日本海的开放，第三纪弧线绕北摄湾顺时针旋转到达现在的位置。
The characteristics of mineral deposits of granitic affinity in Japan, of mostly Cretaceous and Miocene age, have been well established by recent work. In the Korean peninsula, the Jurassic Daebo and Cretaceous Bulgugsa granitic activities are recognized, and Au-Ag, W-Mo-Bi, Cu-Zn-Pb, Fe (-Cu) and F deposits are formed in genetical association with these activities. Some geologic evidence, besides K-Ar age determination data, suggests that major Korean W-Mo-Bi, Cu-Zn-Pb and F mineralization occurred in Cretaceous time. This tentative conclusion makes it possible to correlate the metallogenic features of Japan and Korea for Cretaceous time. The distribution pattern of Cu and Zn-Pb deposits in both countries seems to be related to the present erosion level, that is, Cu is associated with plutonic activity, while Zn-Pb is with hypabyssal to effusive activity. Major fluorite deposits tend to be formed in shallow environments, perhaps related to subaerial volcanic activity. No clear correlation of W-Mo mineralization could be obtained between the two countries. To get the exact position of the southwestern Japan arc in Cretaceous time, reconstruction of the arc relative to the Korean peninsula is attempted (Fig. 4). The arc arrived at its present position by clockwise rotation around the Hokusatsu bend in Tertiary time as a result of the opening of the Japan Sea.
