扩张速率 meaning in English
spreading rate
Examples
- Amore 2001 has successfully investigated the gakkel ridge and arctic ocean in vicinity of its geological and geophysical nature , as well as the nature of sea ice and biology in this area . the preliminary onboard petrology and bathymetry results show that the mantle beneath the gakkel ridge with low temperature has only encountered very low degree partial melting during the spreading and there is no any direct relationship between the crust nature and the spreading rate along the gakkel ridge in any simple petrologic way . mantle temperature and fracture zone density also play a major role on the crust nature , besides spreading rate
对所取得资料的初步研究表明gakkel洋中脊之下的地幔仅经受了较低程度的部分熔融，具有较低的温度。 gakkel洋中脊处的地壳性质和岩浆活动与扩张速率之间不存在任何直接的岩石学相关性，扩张而导致的岩石圈顶部的冷却并不是决定洋脊处地壳性质的最重要因素。地幔温度和断裂带的存在与否及其密度对地壳性质具有重要的影响意义。
