前言在 Sillitoe(1977)提出朝鲜南部庆尚盆地发现的钨(在南部)和钼(在北部)金属成矿省与日本西南部内带发现的(Ishihara,1971)具有相同布局之后,现在日本西南部内带的中生代地块向南漂移的理论似乎是讲得通了。Sillitoe 指出,日本西南部是后期离开亚洲大陆的,因为钼矿区属于早第三纪。如果他的提法是正确的,那么在两个已分开的地区,磁铁矿系列和钛铁矿系列的花岗岩类分布模式必定相似,
INTRODUCTION After Sillitoe (1977) proposed that tungsten (in the south) and molybdenum (in the north) metallogenic provinces found in the Gyeongsang Basin in southern Korea have the same layout as those found in the inner belt of southwestern Japan (Ishihara, 1971), they are now within the southwestern part of Japan The theory that the belt of Mesozoic drifts drifted south seems to be justified. Sillitoe pointed out that the southwestern part of Japan left the Asian continent later because of the early Tertiary. If his formulation is correct, the patterns of distribution of the granitoids in the magnetite and ilmenite series must be similar in the two separate regions,
