Observations of the rock in hand sample have a slight variation to those seen in thin section. In hand sample five main minerals were visible with trace amounts of a sixth seen in very small amounts. Mineralogy in hand sample is k-feldspar, plagioclase, quartz, biotite, magnetite, with trace amounts of hornblende. Texture (hand sample): Overall grain size is coarse grained, with a porphyritic texture, non-foliated. The hand sample has a porphyritic texture with pebble sized, euhedral k-feldspar grains

Yo-Yo Ma is a worldwide known cellist and songwriter who has produced a great number of albums and won more than fifteen Grammy Awards. However, this person is famous for not solely his remarkable talent but also for his significant contribution to the world of music and his not indifferent attitude to the issues of the world importance. Ma's powerful and inspiring speech at the World Economic Forum, in Davos, Switzerland, in January 2008 definitely revealed a number of meaningful issues that concerns

Comparing rocks Minerals make up rocks. Rocks are formed in many environments upon and within the Earth's crust. There are three types of rock, each formed in a different `way. Igneous rock , formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products of weathering by cementation or precipitation on the Earth’s surface. Metamorphic rocks , formed by temperatur e and pressure changes inside the Earth. All three types of rock

Introduction Dimension stones All natural stones* which can be cut to sizes, polished and used for construction purposes, are referred to as dimensional stones.,) including marble, granite and slate { m p _plant) the dimension stones basically consists of two main classes of rocks: “Calcareous material” or “Marble” comprising the whole class of carbonate rocks amenable to sawing and polishing, and “Siliceous material” or “Granite” including the whole set of eruptive rocks having granular structure

Category: Chemistry Experimental Question: How does the temperature of the environment affect the growth of crystals in fudge? Hypothesis: If crystallized fudge is cooled under two different temperatures, then the lower temperature will grow bigger crystals than the high temperature, because solubility in cold temperatures is lower. Why fudge was chosen: Crystals form in igneous rocks, and this experiment was chosen to explore the sizes of crystals formed under different conditions. The topic was

1. How does the rock cycle work? The rock cycle is the repeating process of how igneous rock can transform into sedimentary or metamorphic rock, sedimentary rock changing into metamorphic or igneous rock, metamorphic rock morphed into sedimentary or igneous rock. For example, granite, an igneous rock, forms beneath Earth’s surface, but the forces of mountain building push the granite upward creating a mountain. Gradually, wind and water erosion transform the granite into sand. Wind and water carry

Imagine a rock. A little rock. With speckles of gold and silver. There are two lenses to peer through. A scientific, logical lens tells us the natural processes, the distribution of gold and silver in the ground, the pressure of the sediment above, which all combined to create the rock. The emotional lens shows us what we may not grasp right away. The inexplicable, the emotions which bubble up when look at the rock. Perhaps the rock brings back memories of a grandmother. Or fun times in the park

Manchester State Park, Kitsap Peninsula, Washington: West Beach Outcrop Geology Jason Ott The west beach at Manchester State Park consists of roughly 200m of exposed outcrops with well bedded strata of consisting of the Blakeley formation, of Oligocene age, and poorly consolidated beds of Quaternary age. The northern boundary of the area of interest begins at the southern edge of Middle Point and area terminates at Clam Bay to the south. The Blakeley formation consists of alternating sequence

Caroline Burns 159001444 Museum Assignment 2 3) Basalt is an igneous and mafic rock that compromises most of the volcanic rocks. It is dark black and gray colored. It is rough and has an uneven rectangle-box shape. Basalt is from Somerset and is four point two billion years of age. 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

College. I then transferred to Florida International University where I obtained my Bachelor in geoscience in July 2017. My geology courses helped me become more familiar with the domain of oil and gas. We learned, in classes such as sedimentology, petrology, and mineralogy, about some of the geologic settings where we can find these natural resources and how to identify them in the field. I have also been required to take a hydrogeology class where I learned about different type of wells and how they

Mathematical Exploration: Constructing the Iron-Carbide phase diagram using Gibbs Free energy curves Introduction The first time I heard of the term “phase diagram” was on an online post about the 911 attacks. In 2005, the first installment of the Loose Change film series (series of films which argued in favor of conspiracy theories surrounding the September 11th attacks) was released. The movie suggested that the United States government itself orchestrated the September 11th, 2001 attacks.
