The Ryukyu island arc was not the volcanic island arc, but apart from the EuroAsian continent, the Tugela volcanic belt is the volcanic arc and the Diaoyu island folded belt is the remnant volcanic arc.
文章宏观地论述了冲绳海槽新生代以来的岩石圈的构造演化,提出了冲绳海槽是欧亚板块东缘的独具地质风格的构造单元,一个俯冲型弧后盆地;琉球岛屿是欧亚分离出来的一部分,不是火山岛屿,而吐噶喇火山带则是火山岛弧,钓鱼岛隆褶带是残留火山弧;冲绳海槽的北段形成早、为被动拉张,而南段形成晚、为主动拉张;冲绳海槽未形成洋壳。

The continent in mid-westhern Inner Mongolia is composed of a microcontinent, three volcanic island arcs and three back-arc basins, which are North China microcontinent, Baiyun Obo back-arc basin, Bainaimiao volcanic island arc, Wendurmiao back-arc basin, Sunitezue-Xilinhaote volcanic island arc, Hegenshan back-arc basin and Erlianhaote-Xilinguole volcanic island arc respectively.
内蒙古中西部大陆由一个微大陆、三条弧后盆地和三条火山岛弧，即华北微大陆、白云鄂 傅弧后盆地、白乃庙火山岛弧、温都尔庙弧后盆地、苏尼特左－锡林浩特火山岛弧、贺根山弧后盆 地和二连浩特－锡林郭勒火山岛弧组成。

本文通过对三塘湖盆地石炭系火山岩化学成分、微量元素丰度和稀土元素配分形式等研究,结合构造演化分析,认为石炭系火山岩总体形成于大陆边缘构造环境,但不同时期构造背景略有不同,其中哈尔加吾组火山岩以板内环境为主,卡拉岗组火山岩以火山岛弧环境为主。

The Duobaoshan superlarge copper deposit is a porphyry-type deposit dated at 292～283Ma and occurred in an arc formation of the Duobaoshan Group of Ordovician as well as in granodi-orite and granodiorite porphyry in Hency.
多宝山超大型铜矿床是我国典型的斑岩型矿床，主要产出于多宝山组岛弧建造和花岗闪长岩、花岗闪长斑岩中，成矿年龄为292～283Ma。
补充资料：岛弧
| 岛弧 island arc 呈弧形排列的群岛。弧形凸面朝向海洋，岛弧外侧常有深的海沟，是分割大洋盆地和边缘盆地的重要构造地貌单元。岛弧属构造活动地区，有强烈的地震和火山活动，如太平洋上的千岛群岛、阿留申群岛等。板块学说认为，岛弧是大洋板块向大陆板块俯冲时，大陆板块受挤上拱，隆起而成。 |
