1·Their structural environment is mainly volcanic arc.

其构造环境主要为火山弧地区。

2·Thissimulated natural color image shows Home Reef, located near the Tofuavolcanic arc in Tonga, reemerging after a volcanic eruption in August2006.

这张仿自然色彩图像显示的是2006年8月一次火山喷发之后，在汤加Tofua火山弧附近重新出现的Home Reef。

3·At least 60 large eruptions of Shiveluch have occurred during the past 10,000 years, making it the most vigorous volcano of the Kuril-Kamchatka volcanic arc.

在过去的10000年里，大规模的火山喷发不少于60次，使其成为环千岛——堪察加半岛弧上最具活力的火山。

4·The magma of melted detaching and sinking crystal completely mixes with that of the melted crust in the magmatic chamber of crust, which forms the Palaeogene syncollision and volcanic arc magma.

堆晶体发生部分熔融，拆沉物熔融岩浆与地壳熔融岩浆于地壳岩浆房产生完全混合作用，形成古近纪具同碰撞及弧火山属性的岩浆。

5·They are also found in volcanic “back-arc” basins behind ocean trenches, where one tectonic plate is sliding beneath another.

在海沟后侧的弧后盆地的火山中，此处是一个板块俯冲到另一板块的地方，也发现了该类通道，。

6·Subduction Record Earlier than arc volcanic rocks in the Sangri Group?

存在比桑日群弧火山岩更早的新特提斯洋俯冲记录么?。

7·From the suture line towards the north, an andesite line along Sharburti Mountain was the volcanic island arc developed from middle Ordovician to middle-late Silurian.

由缝合线向北，沙尔布尔提山安山岩线是中奥陶世至中、晚志留世发育起来的火山岛弧。

8·Therefore the volcanic rocks in Chahe and Maomihe belong to the continental arc environment.

上述特征充分说明岔河、茂密河的火山岩属大陆弧构造环境。

9·The (examination) of the petrography shows that the volcanic terrains in Tengchong are typical of the basalt - (andesite) - (dacite) arc volcanic rock associations of the calc-alkaline series.

岩相学特征表明，该火山群为典型的钙碱性系列玄武岩安山岩英安岩弧火山岩组合。

10·Their original rocks are volcanic rocks, epicontinental clastic sedimentary rocks, and ophiolite of volcanic and island arc tholeiitic series or calcium alkali series.

其原岩岩石类型有火山岩，陆缘碎屑沉积岩，火山、岛弧拉斑系列或钙堿系列火山岩、蛇绿岩等。
