Land salinisation manifests at the break of slope and behind rocky subcrop
and angular quartz fields that subcrop
and are aligned with east-west to west-northwest lineaments.
Copper-gold mineralization extends from shallow subcrop
to greater than 400 m to 600 m depth.
Identical facies, and hence the Partridge Island Member, outcrop and subcrop
over a large area, and there are no places the member is absent (except very locally due to faults).
It is very well exposed in the southern part of East Central and Eastern Salt Range and has its subcrop
extension in the Potwar also.
The lateral extent and risk in the north and updip in the east is dependent upon an adequate seal being evident between the subcrop
and unconformity at the base of the lower Grant formation (our geological/geophysical team considers that there is the likelihood of a lower Grant shaley member within the channel non-conformity).
The 3D methodological approach followed was not only the basis for the integration of the surface and subsurface data but was also the basis for the construction of the subcrop
geological map below the Quaternary sediments at the southern edge of the hills.
The Campanario Project has returned significant gold grades, including 18 rock-chip samples of subcrop
and float ranging from 0.
Element of Rare or Geodiversity Common Management aims Rocks & Rare Maintain integrity of outcrop and subcrop
Some interpretations, however, assign at least parts of the Cretaceous subcrop
to the basal Iowa Group (Mississippian).
6) is closely correlated with the subcrop
of the Weardale Granite (although the intrusion of the granite predates the mineralization) and fluid inclusion studies show that orebodies within the fluorite zone were generally deposited at a higher temperature than those in the barium zone.
patterns of the Point aux Chenes Shale and the Mackinac Breccia remain similar on each geologic map.
