The existence of a pockmark directly over a sediment mound at the
unconformity found at a location close to the Oak Bay Fault in Passamoquoddy Bay (Figs.
This cover tectonically undisturbed rests over an
unconformity that is Bajocian in age and forms the base of the Middle Jurassic succession (Dieni et al., 1983).
The Rift or Beaufortian is marked by the Jurassic
unconformity, overlain by a layer of sandstone, the Kuparuk Formation and upper Kingak shale and lower Kingak shale.
Therefore, the layer volume can be obtained by filling the empty space between the underlying layer and
unconformity.
The Permian-Triassic boundary located near Haftad Gholleh is an erosional
unconformity or disconformity, as in other parts of Iran, where Permian sequences contain dolomitic limestone, shale and sandstone situated below the Triassic sequence at a disconformity.
Seismic interpretation reveals a regional Early Miocene
Unconformity (EMU) separating pre-Oligocene to Miocene rifted basement from overlying undeformed Upper Miocene-Pliocene bathyal sediments.
The depth to the Athabasca
unconformity is very shallow, ranging from zero to 350 metres (1,148 ft).
The Paleocene sequence is separated from the underlying Upper Cretaceous sequence by a regional
unconformity with local conglomerate at its base.
New research shows that the answer may lie in a second geological curiosity - a dramatic boundary, known as the Great
Unconformity, between ancient igneous and metamorphic rocks and younger sediments.
The findings described here are also supported, as (1) the Cervini and Muntiacicni split is reported at the transition of Miocene-Pliocene; due to this reason Early Pliocene age is referred to these fossil sites, (2) Some isolated molar remains of Hipparion also indicate the Early Pliocene age, and (3) an
unconformity is present close to the Miocene-Pliocene boundary.
The company has completed five holes in November and December 2011, with two holes encountering anomalous alteration, and another containing chloritic alteration at various intervals below the
unconformity, a common feature found in host rocks containing uranium mineralisation.
The expansion is the result of two years of study by experts supplied via a Compass Foundation grant, and work by the graphic design and communications firm
Unconformity.
