volcanic block的意思|示意

The volcanic activities have relations to the heat-flow upwelling, crust thinning, upper mantle and lower crust melting, and upward movement of the melt materials along the block boundaries.

火山活动与热流上涌、地壳拉伸减薄、上地幔及下地壳物质熔融并沿块体边界向浅部上移有关。

Volcanic ash, lapilli, block and bombs.

火山灰、火山砾、火山块和火山弹。

Based on volcanic activities and tectonic evolution, it is suggested that the tilted fault block, sliding structures in extensional setting should be developed in Cretaceous to Cenozoic age.

结合区域火山活动和构造演化认为，该滑动构造为伸展背景下的掀斜断块型，其滑动时间为白垩纪—新生代。
