Geology in the Canning / Seabee Formations (Lower Brookian) has been characterised by predominantly fine grained siltstones and minor unconsolidated sandstones, interbedded
Jurassic Kimmeridge interbedded
limestone and mudstone sequence.
A sixth occurrence of open water facies occurs interbedded
with poorly drained deposits is present between 853.
We examined two possibilities, that the signature for the newly identified hydrogen reservoir either reflects near surface ice interbedded
with sediment or that it reflects hydrated rock near the top of the Martian crust," said coauthor and JSC cosmochemist Justin Simon.
Carbonate-dominated FA-1 (Facies 7 and 8) consists of thin, lenticular packstone/grainstone, interbedded
with fair-weather bioturbated mudstone/wackestone in the upper Pavillon Member.
The main rock assemblage in this segment is dark-black argillaceous rock containing organic matter (silty claystone, oil shale) interbedded
with sandy dolostone and dolomitic siltstone of approximately isopachous type.
Geologically Nagthat- Berinag Formation of Jaunsar Group of rocks ( types of rocks) containing mainly Karnaprayag metavolcanics ( rocks) and interbedded
quartzites ( type of rocks) are exposed between Karnaprayag and Begali.
The samples from the borings were grouped into different lithofacies based on grain size and include: interbedded
sand, silt, and clay; interbedded
silt and clay; silt; sand; sand and gravel; and diamict.
Fluvio-tidal channel facies successions consist of multi-storey stacks of Fluvial-Dominated, Tide-Influenced and Tide-Dominated Channel Facies Associations interbedded
with minor Bay and Mangrove Facies Associations.
The Braemar Iron Formation consists of a series of alternating bedded, tillitic, and interbedded
magnetite units that represent cycles of glacial advances and retreats.
Samples from the lower interbedded
sequence of limestone and shale were diverse (between 22 to 26 species of 24 genera) and showed high dominance (50-85%) of the genus Sansahella.
The pilot hose was completed in approximately six weeks through interbedded
layers of sandstone, claystone and shale.
