The Great Dividing Ranges also known as the Eastern Ranges are a mountain range geographically located in Australia. The great ranges spand from the north eastern tip of Queensland down southwards to the edge of New South Wales eventually ending in the west most part of Victoria. In total the Ranges length rounds off to a distance of 3,500 kilometres, long enough to earn it the title of third longest land based range in the world. The width of the range varies slightly along its length from…

ancient siliciclastic sequences of river sediments. The value of the technique lies not only in the number of possible minerals, but also in that many of them have petrogenetic parageneses that positively identify the involvement of particular parent rocks. Single grain analytical methods have been most successful in constraining provenance compared with bulk methods (Gehrels et al., 1995; Mange and Morton, 2007). This approach is based on the principle of finding a diagnostic and distinct…

lay large 60 degree a ngeled slabs of rock known as the Flatirons. Over millions of years sediment become compressed into these layers of rock. Clues to what may have caused the tilted sedimentary layers are the darker rock at the bottem called granite, which has no layering like the rock on top of it. The garnite full of menerals showing signs of magma, from a liquid rock. From class I know that magma is usually found deep within the Earth. But this rock has been pushed up causing a tilting…

derived from Jurassic to lower cretaceous periods in the north part of Lake Malawi which has hydrocarbon reservoir prospects. Existence of thick sedimentary sequence rock could possibly trap hydrocarbon especially in lower Shire valley, northern of Lake Malawi. Presence of large proportion volcanic clasts interbedded with sedimentary rocks transported by rivers present for extensive alluvial plain building enhances prospects(Crossley, 1984). The system also swept mud flows generated during…

The Pinturas Formation (Middle Miocene) includes a sedimentary succession exposed at the Río Pinturas valley, Santa Cruz province, Argentina. It is separated in three members. The lower and the upper ones were dominated by ashfall episodes with paleosol formation during stability times; while the middle member is represented by desert eolian deposits. Mentioned palaeosols bears a moderately diverse ichnofauna. Trace fossils presents are Coprinisphaera murguiai, C. ispp., Loloichnus baqueroensis,…

Initially, the most striking feature of Eroded Rock, Point Lobos, a gelatin silver print by Edward Weston, is its relationship between positive and negative space. The photo’s subject is an eroded rock, whose rough, raised plateaus create a light positive space and emerge from smooth, blackened sections of the eroded rock which create the image’s negative space. These sections of eroded rock envelop the plateaus in languid serpentine lines, almost as though the plateaus are land masses cast…

Earth is composed of many different components such as minerals, and rocks. These components have several different properties and characteristics which are unique to each. In this paper, I will discuss some of the different properties, characteristics, and uses of three different factors, those being gypsum, coal, and nickel. Gypsum Gypsum is derived from the Greek word gypsos which means plaster (Gypsum Meanings, Powers, and History). Gypsum is composed of oxygen, calcium, sulfur, and water…

type of shale rocks are chosen because they are “local” rocks which was abundant and available in the lab, also they have very similar mineralogical compositions. Both of the shale samples are provide by the SEER lab (Abiola). Before the tests, samples are cut into piece from the core with thickness about 1 in, and polished to make the top and bottom surfaces parallel. All tests are proceed on Nanovea Indenter perpendicular to the bedding direction. As natural material, the shale rock…

Granophyre is a unconformably overlain by Lower Cambrian sandstones. Micro granite forms in an area with magma and quartz rock. The crystals are smaller than granite, which means that the magma cooled more quickly. A breccio conglomerate with clasts which are both rounded and angular, it is a mixture of breccia and conglomerate. Breccio conglomerate is coarse-grained sedimentary rock, it is present at locality 5. Breccio conglomerate varies in colour, because of the different types of clasts…
