In Parkin Township, the offset dike penetrates the Bruce and Cobalt Groups ( Meyn, 1970 ). The Bruce Group consists of quartzite, arenite, and conglomerate...

... of the Dublin district was given by Farrington (1957) . The most comprehensive general description of superficial deposits in the Dublin area was given by Farrell & Wall (1990) . The deposits were noted to be approximately 20 m thick in the area of the site and to consist primarily of a lodgement till...

A more detailed analysis of soft sediment slump sheets as seen in the Ainsa basin, southern Pyrenees was presented by S. Farrell (Cardiff). These sheets show contractional and extensional strain features, strain overprinting...

... consists predominantly of linear, subparallel, northwest-southeast trending marine sand- stones that are excellent reservoirs for oil and gas (Amajor, 1980). Regionally, the formation is a sequence of proto- quartzites rich in chert pebbles. Interbeds of siltstone, shale and bentonites are common. Eight...

He divides the sandstones into five major groups ( Fig. 9 ): Quartzite (pure quartz sandstone) Feldspathic quartzite (feldspar-bearing clean sandstone) Arkosite (high-feldspar clean sandstone) Graywacke (argillaceous feldspar-bearing sandstone...

Even if there is sufficient iron present in the sediment for pyritization to proceed (cf., Farrell et al. 2009, 2013), the activity of iron reducing micro-organisms is often also...

The Lorrain quartzites at Cobalt Hill consist of angular to subrounded quartz ∠ albite, variable proportions of minor muscovite, carbonate and chlorite. The rocks are albitized, brecciated, and silicified, with several...
