.... Subdivision of these rocks into the Hadlyme and Mamacoke Formations of the Waterford Complex is proposed. Chemical variability identified in the geochemical log is used to divide these gneisses into 44 layers 12 to 30 m thick, and is interpreted to reflect primary compositional fluctuations of volcanic...

... zone separates rocks of the Lyme dome from overlying allochthonous rocks of the Waterford Complex in the “Selden Neck block,” and fault splays isolate paragneisses of unknown age. Splays of the fault extend west, where they cut an extension of the Honey Hill fault zone, narrow slivers of Merrimack...

... and vugs. This complex porosity system occurred after stylolitization, as evidenced by “cuticles” of insoluble stylolitic residue that bridge across small dissolution-enlarged fractures. Porosity detected by wireline logs therefore is mostly effective porosity. The open-fracture network may have been...

An overlying submarine slope succession of the Fort Brown Formation is dominated by channel-levee complexes and entrenched slope valleys ( Figueiredo et al., 2010 ; Hodgson et al., 2011 ). Continued progradation is marked by the ∼400-m-thick Waterford Formation, the focus of this study...

...), and metavolcanic and metaplutonic gneisses and amphibolites (Waterford Group), some of the latter yielding a radiometric age of 620 Ma. Members of the Sterling Plutonic Suite, consisting of granite gneiss and alaskite gneiss, intrude these older units. An exact radiometric age could not be determined...

The onset of zone 2, which coincides with the appearance of the first sandstones in the Waterford Formation, is accompanied by a dramatic increase in transverse resistance and hence the amount of dolerite. This dolerite...

... The fan complex comprises six individual sand-rich fan systems between 20 and 60 m thick, separated by shale-rich units of similar thicknesses. The sixth fan is located to the south and downlaps onto the fifth fan. The sandstone is very fine to fine grained throughout. Each fan system has a high...
