Source and cap rocks
of Kirthar basin are shales ofJurassic Sulaiman group, Cretaceous Sembar, Gorn and Mughalkot, Paleocene Khadro, Bara and Lakhra, Eocene Shaheed Ghat, Sohnari, Laki and Kirthar formations.
The petrophysical properties and geochemical and mineralogical composition of 24 samples of the Deimena Formation reservoir and Zebre Formation cap rocks
from four Baltic onshore and offshore structures were studied and analysed together with previously reported data.
Furthermore, the fracturing of cap rock
"can provide pathways for bitumen and steam to flow to aquifers or to the surface, causing significant risk to safety and the environment.
They are asymmetric and the profile lines demonstrate relations with the shape of the salt body but in a global view there is no visible influence of erosion related to permeability of the cap rocks
located in the western part of the deposit.
The long term storage of carbon dioxide in this case depends upon the type of mechanism that is used to trap CO2 from anthropogenic sources and its storage in the cap rocks
for thousand years.
Fine-grained rocks such as shale or evaporites have the tendency to act as effective cap rocks
2] in geological formations, when a huge amount of gas could be stored in domes covered by impermeable cap rocks
The underground water penetrated cap rocks
at the northern boundary of the salt body and it initiated a subrosion.
Overlying this ancient shoreline are cap rocks
(impermeable layers) of the Mississippian Lower Shunda formation and Cretaceous/Jurassic impermeable shales.
the layer of cap rocks
is partitioned horizontally in two parts: eastern with gypsum-clay cap rock
and western part gypsum cap rocks
Chalcocite has also been found in altered volcanic cap rocks
covering the mineralized intrusive bodies on the west side of the main zone.
The initial drill program will focus on the core area of the porphyry where the leached cap rocks
are associated with anomalous copper geochemistry, high conductivity and low resistivity.
