GORDON Elliott's loss was Oliver Sherwood's gain as Arkose made an encouraging start for his new stable at Huntingdon yesterday.
Etruscan drilled seven holes (A2-04-96 & 97, A2-04-117 to 121) to test a zone of strongly silicified, fractured arkose with abundant quartz stockwork and veinlets striking NW-SE located near the northwestern corner of the A2 Main deposit.

Most of the area where the discoveries are located is underlain by upper tertiary subaerial volcanic rocks with a predominance of dacite, andesite and basalt flows, cross-bedded arkose and felsic asflows.

The only possible tetrapod skeletal remains from the Honeycomb Point Formation are apparently unidentifiable fragments of bone that Baird recorded from the north side of Quaco Head in conglomerate and arkose in 1959 (Baird MS, p.
Arkose is bidding to win this and I think he has a good chance of landing it in the qualifier for the Pertemps Network Handicap Hurdle.
Lithotypes within the lower and upper volcanic assemblages are similar, except for the presence in the lower assemblage of basal conglomerate and arkose (Lynch 1991).
Mineralisation at Area 5 North is associated with narrow quartz veins within an arkose host and significantly, xenotime also occurs finely disseminated within the host arkose unit.
So I'm hopeful of a good run, although Oliver Sherwood's ARKOSE looks the one to beat.
Late Eocene sandstone exposed at the Medicine Pole Hills (MPH) in southwestern North Dakota (11 km south of Rhame) is a conglomeratic arkose that unconformably overlies the Paleocene Tongue River Formation (Fort Union Group).
