未来两个世纪,冰原很可能消失。冰原里的沉积物融化,涌入海洋,不仅引起海啸,山体滑坡,冰原移动,同样也能触发火山喷发。
Apart from the risk that loose sediments exposed by melted ice could slip into the sea as tsunami-generating landslides, the removal of heavy ice could also trigger volcanic eruptions.
一个深海火山喷发出熔岩,研究表明来自火山灰的熔岩烘烤海洋沉积物同时会释放温室气体。
EnlargeA deep-sea volcano spews lava. Research shows lava from such eruptions end up baking ocean sediment and releasing greenhouse gases.
火山岩与碎屑岩共生,构成沉积—喷发韵律或沉积—喷发旋回。
Volcanic rocks compose with clastic rocks together, form sedimentary-eruption rhythm or cycle.
在中期基性火山-沉积阶段,主要表现为玄武质基性火山喷发及SEDEX型铅锌成矿作用;
The SEDEX lead-zinc mineralization occurred in the middle base volcano-sedimentary stage, and corresponds to the base volcanic eruption.
火山沉积型矿床就位于火山喷发旋回顶部;
Volcanogenic—sedimentary ore deposits are situated at the top of volcanic eruption cycle;
根据一般规律,火山的喷发作用从强到弱,最后到沉积,组成一个火山喷发—沉积旋回。
According to general rule, volcano eruption function from strong to weak, finally arrives the deposition, composes a volcanic eruption - depositional cycle.
