在人类太空探索不断取得突破性进展的同时,人们又将好奇与探索的焦点转向了深海。在国外,一些私营投资者也开始热衷于深海探险与旅游,像著名导演詹姆斯·卡梅隆、维珍银河公司总裁理查德·布兰森以及谷歌的埃里克·施密特都纷纷加入到深海潜水竞赛的行列中。其中布兰森的维珍海洋潜水艇或将成为商业潜水艇舰队的首个成员。 相似文献

据有关报告,海底工作潜艇已经在地球的最深海沟发现了生命体。如果把珠穆朗玛峰置于它们的生存处,海水将淹没峰顶,然而,所发现的这些极小微生物群落,却在离地球表面极深的太平洋底部活动着。 相似文献

Zenisu deep-sea channel originated from a volcanic arc region, Izu-Ogasawara Island Arc, and vanished in the Shikoku Basin of the Philippine Sea. According to the swath bathymetry, the deep-sea channel can be divided into three segments. They are Zenisu canyon, E-W fan channel and trough-axis channel. A lot of volcanic detritus were deposited in the Zenisu Trough via the deep-sea channel because it originated from volcanic arc settings. On the basis of the swath bathymetry, submersible and seismic reflection data, the deposits are characterized by turbidite and debrite deposits as those in the other major deep-sea channels. Erosion or few sediments were observed in the Zenisu canyon,whereas a lot of turbidites and debrites occurred in the E-W channel and trough axis channel. Cold seep communities,active fault and fluid flow were discovered along the lower slope of the Zenisu Ridge. Vertical sedimentary sequences in the Zenisu Trough consist of the four post-rift sequence units of the Shikoku Basin, among which Units A and B are two turbidite units. The development of Zenisu canyon is controlled by the N-S shear fault, the E-W fan channel is related to the E-W shear fault, and the trough-axis channel is related to the subsidence of central basin. 相似文献

海沟一岛孤一弧后盆地复合体系的成因与软流圈及岩石圈的流变性有关,以前者为主,并遵循流体运动的最小阻力原理。俯冲有两种类型:一是大洋岩石圈向大陆岩石圈的俯冲,二是大洋岩石圈之间的俯冲。弧后扩张及岛弧升高在时间上的滞后现象,也可以用此原理来说明。 相似文献
