The Gulf of Aden shallow subsurface beach sediments at the mouths of wadis Fuwwah, Ar Rukayb and Shuhair near Al-Mukalla, Yemen are dominantly moderately to well-sorted fine-grained sands, classified geochemically in general as quartz arenite
. Texturally, the sediments show a relatively similar average mean size.
P2304 was awarded to Europa and Arenite
as a Promote Licence in the UK Offshore 28th Licensing Round with an effective date of 1 December 2015, and the OGA has agreed to extend the Initial Term of the Licence until 1 December 2018.
The Mount Simon Formation extends into the subsurface as far east as western Ohio where it is described as tan, friable, moderately sorted, rounded, coarse- to very coarse-grained, siliceous quartz arenite
with minor heterolithic sandstone-mudstone couplets (rhythmites) and a quartz granule conglomerate (Saeed and Evans, 2012).
Despite color differences caused by hematite staining, these bodies are composed of lithic arenite
sandstone comparable to that in the overlying multistorey bodies.
The grotto was formed of arenite
rock, and in it there was a small source of water that formed a small pool approximately two and a half square meters in area and 50 cm deep.
Carving the Stone The stone for the monument, a Carboniferous quartz arenite
, would have been obtained locally and was ideal for carving.
Petrographic modal analysis of Lawrencepur sand shows that the sand is composed of rock fragments and mineral grains that are quartz (47.1%), amphibole (7.7%), quartzite/polygrain quartz (7.2%), quartz mica schist (6.4%), biotite (6.1%), granite (5.8%), carbonate (5.5%), feldspar (4.5%), slate/argillite (2.4%), magnetite (1.9%), epidote (1.8%), muscovite (0.9%), acid to intermediate volcanic (0.7%), greywacke (0.6%), chert (0.5%), garnet (0.3%), lithic arenite
(0.2%), zircon (0.2%) and tourmaline (0.2%).
Soil, classified as Dystrophic Red Arenite
Argisoil, belongs to Sao Pedro map unit (EMBRAPA, 2006) and the region's climate is humid subtropical climate according to Koppen classification (MORENO, 1961), featuring mean yearly rainfall 1769 mm; mean yearly temperature 19.2[degrees]C; mean minimum temperature 9.3[degrees]C in July and mean maximum temperature 24.7[degrees]C in January; yearly sunny period 2212 hours; relative air humidity 82%.
The trackway occurs on the sole of an overlying 38 cm thick, light-gray, mostly medium-grained, lithic arenite
(N 70[degrees] E, 50[degrees]NW, Fig.
2000) resulted in recognition of the first-reported occurrences in Canada of quartz arenite
containing stromatolites and biofilm structures (Fig.
Around 80 percent of Brazil's current domestic oil output of about 1.9 million barrels a day comes from the Campos Basin at much shallower depths from arenite
rock, which allows Petrobras to re-inject gas and water to maintain oil pressure.
Samples located in deep water (> 20 m) were composed of moderately sorted coarse silt (38 [micro]m-63 pm) with shell and organic fragments, whereas those at shallow depths (< 10 m) were composed of very well sorted very fine arenite
sand (63 [micro]m-125 [micro]m; Table 1).
According to Folk's (1980) classification, 80% of the plots fall under Quartz arenite
field whereas 20% falls in the Sub-lithiarenite field (Fig.5).
The detrital component of the rocks of the Vadja Fm is mainly arenite
, containing quartz 50-65%, feldspars 15-25% and micas 5-30% (Fig.
