Siltstone

The Tuscarora formation is a light-gray sandstone with quartz grains imbedded throughout it. Most exposed Tuscarora specimens were dark and weathered on the exterior but were light colored on the interior and comprised of fine to coarse grains. The Tuscarora formation is about two hundred meters thick. The Castenea formation is found in parts of the Tuscarora formation. It is typically observed as a dark brown-reddish layer binding a middle section of lighter brown fine grain well sorted sandstone. The Castenea is an average of fifty meters in thickness. The Rose Hill formation is the thickest formation of surface bedrock in this area at about two hundred and fifty meters thick. This formation is a layer of shale ranging in color, mainly a light red-grey shale, but also could be light greenish-grey or dull brown.. The Keefer formation is a fifteen meter thick hematitic sandstone unit. It is grey to yellowish-brown and displays fine to medium grains. The concentrated iron induced orange or bright red hematite components of the Keefer are eye catching and easily distinguished. The Bloomsburg Formation contains a red or reddish brown mudstone and a grey - red shale. This formation is around 200 meters thick. Map Scale Structures Examining the map generated through applying the data collected in the field, six “map” scale structures are revealed. Three sinclines and three anticlines run diagonally across the map from the south – west corner to the north – east corner of the map…

that can be found at Marino Rocks include: sandstone and siltstone. Sandstone is a sedimentary rock composed of sand-sized grains of mineral, hence why its called ‘SAND-stone’. It also contains a cementing material that binds the sand grains together. This is in contrast to siltstone, silt is a size term used for material that's smaller than sand but larger than clay, once again, this is why it’s called ‘SILT-stone’. The siltstone at Marino Rocks is generally mostly pure, containing very little…

is a small quarry face. This is where the siltstones are present. Siltstones are sedimentary rocks, that are formed mostly from silts and are well sorted. They are predominantly grey, with a hint of green. The green colour comes from the glauconite mineral. The siltstones are formed in low energy continental shelf marine depositional environment. The silts settle on the river bed and over time with pressure they have the water squeezed out of them and it turns into siltstones. There is a…

The exposed rock material has a visible reverse fault, and is heavy faulted/folded. Visible soil, and vegetation growth on exposed section of the formation. Visible iron oxide staining from fractures in the section both natural, and manmade. Alternating material layers light grey to dark grey in the formation, and thick bands. 0 to 3feet of the section is composed of light grey, and soft material. The bottom facie was a small section of laminated layered shale. 3 feet to 6 feet of the exposed…

The Mt. Isa Mine is a deposit of copper, lead and zinc. It is located at latitude 20∘44’S, longitude 139∘29’E and is in Queensland (Forrestal, 1990). Generally, this ore deposit contained 123 g/t copper, 5.0% lead and 7.0% zinc at 4.8 Mt. The host rock of this deposit consists of pyritic shale, carbonaceous shale, dolomitic siltstone, carbonate, granite, ironstone and metasedimentary cover rocks (Hutton et al. 2012). Deposit genesis The ore deposit genesis is considered to have occurred in…

The Sugarloaf Arkose makes up the basal unit and reveals a fluvial and alluvial arkose environmental deposition. The dominant sandstone grain size is evidence of a fluvial depositional environment at Stop 2. The Late-Triassic age alluvial and fluvial arkose of the Deerfield Basin makes up the main strata sequence. Stop 3 reveals the Deerfield Basalt followed by lava flow in the strata column. The transition between Fall River Beds and Sugarloaf Arkose is at the Triassic and Jurassic boundary…

Mineralization is independent of igneous processes. Host rocks comprise two types: calcareous or dolomitic siltstone, shale, and carbonate rocks of marine or lacustrine origin; and non marine sandstone, arkose, and conglomerate. In addition, the iron oxide copper-gold and basaltic copper deposit sub models may be applicable within some of the areas studied. Deposits of the reduced-facies subtype (model 30b.1; Cox and others, 2003), also termed coppershale or stratiform copper deposits, are…

in ancient Egypt. “The Palette of Narmer” expresses the innovative techniques of raised relief carvings and the use of fine siltstone to depict the narrative of King Narmer’s unification of Egypt. The line work and composition of this piece define the rarity of the palette as a ritual object, instead of being used for grinding cosmetics for everyday usage. The iconographic appeal of “The Palette of Narmer” is the historic unification of Egypt through the military power of King Narmer (and his…

The DeGray Dam Spillway east and west walls have similar lithofacies, and are approximately 100 m apart. The authors examined 8 lithofacies types in their study area: massive sandstone, sandstone with floating mudstone clasts, pebbly sandstone, contorted sandstone, contorted shale, mudstone/shale with floating clasts, laminated and rippled sandstone and siltstone, and laminated shale. These lithofacies were interpreted based on depositional processes. At DeGray Spillway, 794 units were measured…

form annual growth rings- bones also have yearly indicators of growth. By comparing the oxygen isotope levels of each year indicator of the bone with isotopes of the surrounding areas we can see where the Tyrannosaurus rex may have traveled to throughout its life cycle. Assuming the oxygen isotope levels can be calculated for the areas of Interest, the bulk of our grant would be spent cutting the oxygen isotope levels from existing fossils. Using USGS maps we can pinpoint locations of…
