Advantages And Disadvantages Of Marble

The rocks do not show signs of heavy weathering. There is some white staining visible, but there is very little red or brown staining. The rocks have abundant vesicles. There is a mix of rocks with varying sizes and numbers of vesicles. Samples collected were representative of this mix.

Rocks also do not have crystalline structure. Rocks also can include fossils where minerals cannot. Minerals colors are generally the same. Rocks vary in color.

This phenomenon is called a thermally inverted pattern, in which the subducting plate becomes folded and the layers of rock bend. This bend led to the Catalina Schist which is where you will find amphibolite on top of the green,

Hematite, quartz, and clay are the mineral in rocks. It was deposited in beach from environment. The event recorded here is a transgression of sea level (intercontinental seaway). Benton Shale Formation was our next stop. Its 90 million years old.

This is due to the fact that when magnesium is burned in air, its contact with oxygen causes it to become a brilliant white color (Stewart

Basalt is mostly composed of augite, plagioclase and olivine. Augite comes in many shapes – cylinder, square, rectangular - but is usually rough and grayish black. Plagioclase is whitish brown and usually has a cubic shape with ragged edges. Olivine can be green, yellow or brown. It is usually three dimensional and octagonal.

However, only about a quarter comes from sedimentary rocks. According to USGS. The Statue of Liberty was not always the green color it is now. The Statue of Liberty used to be a dull brown. It slowly turned to the green color because the copper undergoes a oxidation reaction.

Pebble Mine Pros and Cons: Which Side Are You On? Mineral exploration has been done for centuries, and it is always associated with advantages and disadvantages. The Pebble Mine in the Bristol Bay region of Southwest Alaska is no different. This type of mine involves extraction of low grade copper-gold-molybdenum sulfide deposits. During the world recession, pebble mining was one of those businesses that saved many countries.

3. Hard siltstone: a much harder and heavier siltstone type of rock overlies the shale. It starts out gray color and becomes red and yellow as it moves higher. This is the layer where most of the fossils are found. Splitting is sometimes very difficult because of the hardness.

At the conclusion of my speech today you will each be able to explain what the Georgia Guidestones are, where they are located, some basic physical characteristics, and what the message is to be conveyed and to whom. Attention getting opening statement. - Introduction Imagine in a world of over 7 billion people a cataclysmic, near extinction level event (ELE) has occurred, in which nearly all of the world’s 7 billion people have died or been killed and a mere 500 Million survive. Because that is exactly what has happened in the mind of RC Christian (A pseudonym) When he conceived and created the Georgia Guidestones.

The Purpose of Stonehenge Stonehenge, a collection of monoliths in England, has been around since 1600 B.C. (“Stonehenge”). The ruins are composed of almost 100 chunks of sandstone and bluestone (“Stonehenge”). A number of the larger stones were made into “iconic three-pieced structures call trilithons” (“Stonehenge”) that many still recognize today.

Over time sediment built up and was turned into sedimentary rock by the intense pressure. Deep below this sedimentary rock, magma was slowly cooling and turning to rock. This lava took a long time to cool and became harder and harder over time. This magma turned into granite. The softer rock such as the sedimentary above the granite was eroded away revealing the granite that did not erode much if at all because of its hardness.

After studying puzzling stone balls found near ancient stone circles in Scotland that resemble Stonehenge, they concluded that Neolithic workers may have used wooden or stone balls and long grooved planks to slide the heavy slabs all the way from Wales. With a team of oxen, the researchers estimate, Stonehenge’s creators could have transported the massive rocks some 10 miles a day, taking roughly two weeks to make the trek from the Preseli Hills quarry to the construction site in
