..., it is typically modeled using only single-phase functions due to a lack of fault rock relative permeability data and complexities in incorporating two-phase flow properties into flow simulations. Here we present two-phase fluid flow data for cataclastic fault rocks in porous sandstone from the 90-Fathom fault...

...Fig. 5.  ( a ) Location map of Northumberland Basin. ( b ) Detailed structural map of the 90-Fathom Fault at Cullercoats showing mesoscale structures (i.e. normal and strike-slip faults) in the hanging wall. ( c ) Simplified structural map of Northumberland Basin, showing main bounding faults...

.... A. Howell of the Coast and Geodetic Survey steamer BACHE, who conducted a reconnaissance survey of this general area in 1872. Beginning in 72 fathoms, 4 fathoms deeper than a similar but much smaller ridge slightly southeast, the crest of the ridge deepens to 90 fathoms at its northerly end. The ridge crest...

... inshore and offshore from these depths is marked by significant configurations. In the shoaler depths of 25-80 fathoms the bottom irregularities consist of ridges, troughs, domes, abrupt gradient changes, some escarpments and nose-like protuberances of 40-60 fathom depths from 70 to 90 fathoms. Except...

.... The break is not noticeable on all fathograms, but small irregularities between 90 and 100 fathoms in this region are generally in evidence. It is interesting that these depths approximate the depths at the tops of high ridges previously mentioned. Micro-relief at the bottom of Zone one will probably...

...). Certain ENE-WSW trending faults were reactivated by post-Variscan extension, e.g. the 90 m normal displacement of the base of the Permian on the Ninety Fathom Fault (Fig. 2), and this reactivation occurred most obviously across the buried southern basin-margin. Deformation of the Permian basal surface...

... to the west for 150 miles. Where the survey was discontinued, in depths of 2,200 fathoms, the leveed canyon was still a prominent feature. At the 550-fathom contour the canyon is about 5 miles wide at its rim and 500 fathoms deep. The canyon is V-shaped and echoes from the thalweg are usually recorded after...

... to 220 by an examination of fathograms. Shepard (1948, pp. 175-90), based on a chart study of the entire world, reports that the upper 1,000 fathoms of continental slopes vary in declivity from 1° to 25°. It might be argued that the variation is due to a reduction of slope by slumping of beds...

... by integrating this line with other data, and a Tricentrol seismic profile confirms the suitability of this model. The trough has a markedly asymmetric form, with a thickness of more than 4.2 km of Dinantian strata adjacent to its faulted southern margin. The present day surface faults (Stublick, Ninety Fathom...

... of the samples have as high as 90 per cent of their total material in one grade size and four others have more than 80 per cent in one size. The best sorting is found in general near the shore, four samples of the six mentioned being found in water of less than 5 fathoms depth. However, good sorting was found...

... excursions to the Point Conception area during the winter of 1961–1962. The mounds photographed are in 90 feet of water 1½ miles offshore, several miles east of Point Conception. Tar mounds have been observed on the southern California sea floor in only three localities: the Point Conception area, Coal...

...K. O. Emery ABSTRACT A large collection of bottom samples and underwater photographs from the top of a 67-fathom flat-topped bank off Baja California, Mexico, was studied. The data indicate that wave action bevelled Jurassic (?) metamorphic and Miocene (?) volcanic and sedimentary rocks during...

... to the 10 principal cyclothems (Four Fathom–Peghorn limestones) of the Alston Block, together with the underlying Birkdale Limestone at the base of the Alston Formation from which the lowest Brigantian microfossils have been recorded. The underlying Great Scar Limestone Group of late Asbian age (148 m...

... Pennine Batholith, along the Ninety Fathom Fault. The Fell Sandstone traversed by the borehole proved to be of low hydraulic conductivity ( c . 7 × 10 −5 m d −1 ). The water that entered the well was highly saline, with a Na–(Ca)–Cl signature similar to other warm waters encountered in the region...

Structure .—The submerged areas studied in the present survey show no significant variation from the geology of the sub-aerial part of San Nicolas Island. The strikes...
