They may also contain sands and other more recent geological materials occurring unconformably in the geological sequence.
The mineralization is interpreted to be associated with a shallow sub-basin unconformably overlying the carbonates that host widespread MVT (Mississippi Valley Type) Zn (dominant) - Pb occurrences.
The gold produced at Blackridge was mostly hosted in basal conglomerates of Permian-aged sedimentary basins which include the mined coal measures that unconformably overlie the Anakie metamorphic rocks of Middle Ordovician age and older.
The Abbottabad Formation unconformably over lies the Precambrian Tanawal Formation in the hanging wall of the Panjal Thrust in the Sherwan area but overlies the Hazara Slates at Soban Gali and Sirban Hill in the footwall of the Panjal Thrust (Pogue et al, 1999).
The oldest is Alam El Bueib which is a thick succession of clastic rocks deposited unconformably over the eroded surface of the Jurassic Masajid marine carbonates.
(1) Information from synsedimentary deformation structures reveal two major stratigraphic units: a lower deformed unit, unconformably overlying by a nondeformed unit.
To the east of the basin a thrust fault is in contact with Late Triassic limestone, while to the west Carboniferous and Permian organic limestone is unconformably overlain by Tertiary units [49].
Then, Mesozoic sedimentary units were unconformably succeeded by Miocene-Pliocene fossiliferous limestone, marl and poorly fossiliferous massive mudstone and sandstone of the Taslica Formation [21].
Rocks of the Fredericton trough in New Brunswick are assigned to several formations of the Kingsclear Group (Fyffe 1995), which are overlain unconformably by Carboniferous rocks of the Maritimes Basin (Fig.
Remains of the Late Carboniferous to Permian molasse basins rarely overlie the Variscan basement unconformably (Cassinis and Ronchi, 2002), forming a more than 300 m thick succession that locally (SE Sardinia) also includes thin Middle Triassic deposits (<50 m) (Costamagna and Barca, 2002).
The basement is unconformably overlain by Early and Late Cretaceous marine strata represented by the Caballlos, Villeta and Rumiyaco Formations (Amaya y Centenaro, 1997), followed by the continental Pepinos Formation and a widespread Neogene volcanic cover (Mora et al, 1998; Murcia and Pichler, 1987).
