查询词典 abyssal

Recent studies of abyssal peridotites show that they are not melt residues of batching or fractional melting of pyrolite directly after melt extraction of MORB. Petrological studies of peridotites from Luobusa ophiolite massif also indicate that the mantle peridotites are not simple residues of primary pyrolite either.

罗布落蛇绿岩橄的镜下观察和岩石化学资料也证明，它不是原始地幔岩经局部熔化后的残余物，而且由来自更深层的地幔过渡带的硅酸盐超高压矿物底辟上升经熔取出玄武质熔体后，再次局部熔化后的残余物。

In order to deepen understanding in the MQZ at the northern continental margin of the South China Sea, this paper summarized three possible occurrences of the global MQZs originated from physical, chemical and structural processes, respectively, located at marginal zones and abyssal zones of the global oceans, mainly Jurassic MQZs both in the Atlantic and the western Pacific, Cretaceous MQZs in the northern Pacific, the Indian and in the Southern. Meanwhile, it is worth attaching importance to mantle plume activities in different scales, small magnetic sources induced by initially fragmented ridge oblique to the continental margin and faint magnetic lineations in those MQZs.

为了加深认识南海北部陆缘磁静区，归纳了全球深海和边缘两大类型磁静区的物理、化学及构造三大成因，主要包括大西洋和西太平洋侏罗纪磁静区，以及北太平洋、印度洋和南大洋白垩纪磁静区，强调磁静区与不同程度地幔柱活动、斜交扩张初始产生的小型错断磁源体及隐含弱磁条带关系的重要性。

The depositional energy is low, the abyssal plain is flat and nearly horizontal, and find-grained sediments are deposited slowly by waning turbidity currents or from suspension in the water.
