The oldest rocks in the CV are low-grade metamorphic rocks of Upper Devonian age
overlied by lower Carboniferous volcanic rocks with scarce sedimentary layers and upper Carboniferous clastic marine sediments.
However, careful analysis of the fossil data indicates a Late Silurian (Pridolian) age for the fauna, and shows that the evidence used to assign a Devonian age
should have been regarded as provisional.
The proposed Wade Hill-1 well will target Devonian age
formations and resembles the Gilmore gas field.
In the Ohio Range, located south of the Pensacola Mountains, typical Malvinokaffric faunas of Devonian age
are similar to the South American faunas.
Composition and properties of the iron hydroxides - cemented lenses in Estonian sandstone of Middle Devonian age
It is planned to tag the Late Devonian age
basement at TD of around 1350 mRT.
Ostracodes from both the Hersey and the Eastport formations of coastal Maine are indicative of an Early Devonian age
Following the discovery made in the Upper Devonian section of the Poti Formation, announced on November 17, 2010, the drilling of the well OGX-22 continued and a new accumulation of gas in the Lower Devonian age
of the Cabe[?
If we apply the general Middle Devonian age
of these longer-ranging species to the Rezekne RS, we shall get a reverse age determination: the longer-ranging species determine the age of an earlier unit.
The property lies along the margin of a north-south trending carbonate window where Devonian age
limestone of the Denay and Devils Gate Formations is exposed through the Roberts Mountains Thrust.
Similar Devonian age
limestone is a favorable host for sediment-hosted gold systems elsewhere on the Battle Mountain -Eureka Trend.
There are some more indications of the secondary magnetizations of Early Devonian age
from the igneous rocks of Kalak Nappe Complex, northern Norway (Torsvik et al.
Oil production in the region comes from marine limestones of the Devonian age
It is believed that the well did not reach Devonian age
rock as perceived by the geological field survey of the cuttings during drilling of the well.
Primary oil targets will include the Mission Canyon & McGowan formations at 5000 - 8000 feet; the Devonian Age
Baaken & Nisku formations at 7000 - 9000 feet.
