reaching that part of the basin of deposition, and probably a depositional site far from shore. Most of the Paleozoic carbonates were originally composed of calcite but were altered by the replacement of calcium ions by magnesium to form the mineral dolomite. The St. Lawrence Formation is not clean but contains clay, silt, sand, and glauconite, indicating fluctuating conditions. The Jordan Sandstone is 25 to 35 meters thick, and variable in sandstone type. The Jordan Sandstone is either a white or
Two properties are required for fluid movement of Reservoir rocks and Source rocks: permeability and porosity. It consist voids or pores, ability to contain fluid (known as porosity) and the pores are interconnected (permeability) in order to allow flow to occur. Hydrocarbons can be termed as reservoir fluid. The volume of hydrocarbons stored in a reservoir depends upon the porosity of the reservoir rock. The rate and volume at which hydrocarbons are withdrawn depends upon the permeability of the
Introduction Cortina d'Ampezzo is located in Northern Italy and is one of the most famous ski resorts. Settled in the middle of Dolomites alpine valley, Cortina d’Ampezzo is seen as a best practice winter sport resort with wide range of activities for the visitors. Furthermore, it’s known for the hosting of Winter Olympics in 1950’s, plus various World Cup events (such as World Cup skiing circuit for the women's speed disciplines) and motion pictures, e.g. The Pink Panther. Cortina d’Ampezzo
There are three different types of rocks. We should know about • Igneous • Sedimentary • Metamorphic Sedimentary rocks are made of fragments of other rocks; igneous, metamorphic or sedimentary. They are made when an older rock erodes or weathers to produce sediment, for instance sand on a beach. The sediment is then compacted and cemented together to produce a rock. Sedimentary rocks can also contain individual grains of minerals which have been eroded out of older rocks. Igneous rocks are formed
this was because the marble began as limestone. During the late Precambrian era this place was covered by warm sea water. When magnesium was added to the limestone it changed the rock to dolomite, which is a magnesium-rich sedimentary rock. When time began to go on younger rock covered the dolomite. The dolomite was influenced by the pressure and temperature of being covered and this caused the rock to transform into
3- What are porosity and permeability? What do these parameters depend on in a geologic setting? And how is diagenesis involved? Porosity is a measure of how much of a rock is open space. It also is a measure of its ability to hold a fuild. The porosity can be between grains or within cracks, or cavities of the rock. Permeability is a measure of the ease of flow of a fluid through a porous solid. A rock may be extremely porous, but if the pores are not connected, it will have no permeability. Likewise

The Brown bears population in Europe was on the brink of extinction in western Europe and a team of scientists teamed up to create a healthy balance and now the population is steady growing and healthy as ever. The Brown bear ( Urcus Arctos ) or more is a species of bear with a population of around 200,000 mostly in North America and the Russian Federation . Deemed as least concerned on the conservation status International Union for Conservation of Nature or ICUN for short. With a fairly large
In forestry terminology, silvicultural systems describe the sequence of treatments by which a stand is harvested, regenerated, and tended to produce timber and other forest products. (Clayoquot, 1995). The silvicultural system currently implemented on Witklip plantaion is that of an even aged stand known as clearfelling. Silviculture involves an applied forest ecology approach utilizing silvicultural practices such as the control of stand structure and processes, control of composition, control

Barites are a solid mineral that combines barium and Sulphur. It is composed of Barium sulfate (BaSO4). The word barite is a Greek word derived from the word “barys” which means “heavy” which is with regards to its high specific gravity which makes it exceptionally suitable for its many applications in areas of medicine, manufacturing and industrial uses. Barite is the principal ore of Barium. Pure barites contain the following below (“Barite Mineral Data,” n.d.) Chemical Formula: BaSO4 Composition:
Valley Region of the Appalachian Mountains and Subsequent Karst Regions in the State of Virginia This map which appears on page 402 of Process Geomorphology (1995), written by Dale F. Ritter, Craig R. Kochel, and Jerry R. Miller, serves as the basis of my report on the formation of the Appalachian Mountains and its subsequent karst regions in along the Atlantic side of the United States particularly in the state of Virginia. The shaded areas represent generalized karst regions throughout the
Introduction Out of the United States, Alabama was rated sixteenth among the states because of their industrial minerals produced. The industrial minerals that were produced were limestone, lime, dolomite, crushed stone, marble, building stone, sand, gravel, chalk, clay, shale, kaolin, bauxite, bentonite, fuller’s earth, fireclay, recovered sulfur, salt, and mica. In 2007, Alabama’s value of industrial minerals was about two percent of the national mineral production. In 1998, Alabama was ranked
Glacier National Park preserves more than a million acres of forests, lakes, rugged peaks, and glacial carved valleys (Winston, 2013). Glacier National Park is named for its glacier-carved terrains and remnant glaciers from thousands of years back. Geologic forces such as geologic faults and uplifting have created some of the most spectacular views in the park. Held in this park is an impressive geologic story that geologist depicted by examining various features in the park. One of the most striking

Gudea belonged to the neo Sumerian culture dated 2090 B.C. from the ancient Mesopotamia. BODY Briefly describing the statue of Memi and Sabu we can say that the media was limestone which is a sedimentary rock composed mainly by calcium carbonate or dolomite used for sculpture material in the ancient work and still used in buildings today. On the other hand the sculpture media of Gudea was Diorite, which is an igneous rock composed
When someone accidentally touches a smoldering oven rack, they are not presented with adequate time to consider every manner they can react. Within a split-second, the human will retract their hand in order to avoid further agony and save their skin. In this circumstance, the sensory nerve which perceived the pain will bypass the brain and reconnect directly to a motor nerve near the spinal cord, which will in turn cause muscles to withdraw the hand. This life-saving device, called a reflex arc
secret was his name! Titian’s real name was Tiziano Vecellio. It’s a weird name, I can see why he would want to be called something else, wouldn’t you? Tiziano Vecellio’s birth time is undeterminable, although we do know where he was born, in Dolomites, Pieve di Cadore (http://www.boglewood.com/cornaro/xtitian.html).
Minerale Metalor Minerali i Kromit Shqipëria është e njohur për potencialin e tij të lartë në mineral krom, krahasuar me vendet e tjera të Mesdheut dhe të Ballkanit, me anë të secilës dikur kemi zënë vendin e tretë në botë, për prodhimin e kromit pas Afrikës së Jugut dhe Rusisë. Para viteve 90’ ndëroji drejtimi ynë drejt mineraleve metalore, qymyrin. Ndërsa tani tendenca ka ndryshuar edhe më shumë duke shkuar drejt mineraleve jo metalore, drejt gurëve dekorativë, argjile, gipse, zhavorr, inerte etj
Chernobyl 1986 was a year of several meaningful worldwide events, some of which included the Voyager 2 got details and pictures of Uranus, the space shuttle Challenger exploded on takeoff, and Haley’s comet soared past Earth (infoplease.com). Perhaps the event that alarmed the world the most, however, was the major nuclear accident that occurred at the nuclear power plant Chernobyl. The nuclear disaster that occurred at Chernobyl in 1986 (Lecture 4/1/02), has forever changed the
