It is argued that a reliable theory of the stress history of the Moon should take into account several factors; and that direct observations of the Moon's surface can throw much light on this subject. 相似文献

The paper deals with the morphology of the stretch of coast between Boscastle and the Treligga Cliffs in North Cornwall. The prevalent cliff type is slope-over-wall, either hog's-back or bevelled as defined by Miss Arber (1949). Flat-topped cliffs are less common. It is considered that geological structures—bedding, jointing, faulting and, to a lesser extent, rock-type—have not only had considerable influence on the shape of the cliffs, but have also guided the marine attack on the coast. The evolution of most of the coast features, when seen in plan or profile, has been controlled by the local geological structure. The southern stretch of the coast is sub-parallel to seaward-dipping normal faults which have been stripped of their hanging-walls. Such a cliff line is dominantly a faultline scarp which has suffered slight retrogression. 相似文献

Modern side-scan sonar technology was used to resurvey the site of the Howe Sound submarine slide described by Terzaghi. Chutes,
hummocky topography, and subparallel scarps indicative of submarine mass movement are widespread. Submarine slope processes
appear to be far more important to the development of this coarsegrained fan delta than suspected. 相似文献

The present study indicates that most semiconductor components are fabricated such that they are not affected by operation in a dielectric oil environment. A quantitative estimate of the conditions under which oil-soluble ions will invert semiconductor surfaces and interfere with proper device operation is developed. The results are discussed in terms of pressure-tolerant electronic systems—solid-state components operated immersed in chemically inert dielectric oils when these components are subject to, and experience, ambient hydrostatic pressures of the ocean depths. The feasibility of pressure-tolerant electronic systems is demonstrated. 相似文献

In this work we attempt to estimate the short- and long-term effects of the Amoco Cadiz oil spill on benthic microalgal populations (cyanophytes and diatoms) which, under natural conditions, live on upper layers of ‘schorres’ soils or of ‘slikke’ muds in the Ile Grande salt marsh system (Côtes du Nord, France). These populations were completely destroyed in 1978 in the oil-affected sites. Ubiquitous species settled fairly rapidly on intertidal polluted muds (tidal flat). The chlorophyll a content values reached 100 μg g−1 dry sediment, i.e. 1000 mg m−2 in 1980. Conversely, the salt marsh soils are still much less densely repopulated 3 years after the Amoco Cadiz grounding—especially when they are infrequently flooded (3 to 40 μg Chl.a g−1, i.e. 40 to 270 mg m−2). Some of these soils remain ten times less populated than reference stations. 相似文献
