深海平原

火山碎屑矿物主要分布于15°N两侧的深海平原和海山区，来源于海底火山岩的剥蚀物和附近弧状列岛的火山喷发物。

The volcanogenic minerals mainly distribute in the abyssal plain and the seamount near the latitude of 15 ° N , mainly come from the erosion of the volcanic rocks in the seabed and the volcano eruptions in the vicinity of islands .

南海深海平原铁锰微粒的初步研究

A Preliminary Study on the Ferromanganese Particles of the Deep Sea Plain , South China Sea

某&天大陆会降沉，而金属核却又踏上了跨越深海平原，回归到出发点的旅程。

At one time the continent will sink , and the nodule resume its journey over the deep-sea plains , toward its starting point .

盆地的构造特征东西部明显不同，西部为深海平原，发育少量正断层，地层无变形；

The whole sedimentary section within the basin is a wedge thickening from west to east , and the tectonic characteristics are obviously different in the basin .

结论香山群形成于伸展构造背景下的被动大陆边缘中的大陆斜坡和深海平原环境。

Conclusion The record of deposition-magmatism of Xiangshan Group reflects that the environment of continental slope and deep ocean plain formed in the background of spreading tectonics .
