Its tectonic environment may be the spreading ridge of a small oceanic basin at the start.
结果表明，菲律宾海和南海显示了与磁条带、扩张脊对应或斜交的高频成分大地水准面起伏条带。
The results show that within the Philippine Sea and the South China Sea, short - wavelength lineations of the geoid undulation are parallel or cross to magnetic lineations and rifting ridges.
造山带富集型上地幔形成的构造环境是：洋壳从扩张脊向两侧运移并最终拼入造山带这段时间内。
Tectonic environment of formation of enriched upper mantle is oceanic crust displacement from the oceanic mid-ridge to the orogenic zone.
通过对该蛇绿岩带地质及岩石地球化学特征等进行了论述，认为其形成于近弧的弧后盆地扩张脊环境。
This paper discusses the feature of geology, lithogeochemical of this ophiolitic belt, so the ophiolite is produced from near the back-arc basin spreading ridge.
虽然辛顿和鲍尔斯目前只考察了加拉帕戈斯扩张中心的一小部分，但他们已有的数据将帮助他们最终了解该海脊是如何形成的。
Though Sinton and Bowles have only explored a small portion of the GSC, they already have data that will help them eventually understand how the ridge formed.
印度洋脊是中大洋脊的一部分，中大洋脊是地壳分离的地球板块形成的。这一形成过程被称为海底扩张。
This is part of the system of mid-ocean ridges that form as the tectonic plates of the Earth's crust move apart-a process known as sea floor spreading.
这一区域被认为是“标准的”(normal)大洋中脊，也就是说它具有包括海山在内的多种火山地貌，正是科学家们在加拉帕戈斯扩张中心的理想观测点。
This area is considered a "normal" mid-ocean ridge, meaning it exhibits many volcanic features, like seamounts, scientists would expect to find at places like the GSC.
