Igneous Rocks ROCAS IGNEAS PLUTONICAS En este capitulo, consideramos la familia de las rocas ?gneas intrusivas - granito, gabro y otras de la misma familia - las cuales se cristalizan, desde su fundici?n a grandes profundidades en la corteza terrestre y que luego son tra?das a la superficie por la erosi?n de las formaciones superiores. La g?nesis desde una fundici?n a alt?simas temperaturas (aprox. 900?C), y kil?metros de ascenso imprimen caracter?sticas especiales en estas rocas. Tambi?n consideraremos las particularidades qu?micas y mec?nicas de la inusual roca: serpentina, la cual se origina en el manto terrestre, en algunos casos ascendiendo en estado s?lido con grandes deformaciones internas. Contrariamente a la serpentina que generalmente presenta problemas desde el punto de vista ingenieril, las rocas gran?ticas son generalmente consideradas como el mejor aliado de los ingenieros, con buenas cualidades, sin meteorizaci?n y sin fracturamiento el granito es el prototipo de un lecho de roca. Sin embargo, generalmente las rocas gran?ticas presentan meteorizaci?n o fracturamiento, o ambas. Esto puede generar muchos problemas. Las rocas gran?ticas las encontramos haciendo parte de los n?cleos de gran cantidad de monta?as y en otros lugares donde existieron elevaciones. Principalmente en aquellas regiones llamadas escudos. El escudo Canadiense cubre la mayor?a de la zona este del Canad?, que se extiende desde las Monta?as Rocosas hasta la regi?n de los Grandes Lagos en U.S.A. Existen escudos similares de rocas gran?ticas que se encuentran bajo la superficie de Brasil, El oeste de Australia, Africa, Escandinavia y Siberia. Un gran porcentaje de roca de estos escudos se asemeja al granito, pero pueden haberse formado por metamorfismo y no por solidificaci?n de masa en fusi?n. Las rocas de tipo gran?tico tambi?n pueden encontrarse en masas separadas de varios tama?os y formas, en intrusiones de rocas de diferente tipo fuera del n?cleo de cualquier zona monta?osa. Entre este grupo se encuentra granito plut?nico terciario que se presenta en la zona este de U.S.A y generalmente est?n asociados con dep?sitos de mi neral. Las rocas plut?nicas son especialmente fascinantes para los ge?logos, ya que estas son mensajeras del interior de la tierra. Su composici?n y texturas nos presentan hechos, que con una buena interpretaci?n pueden revelar la temperatura, presi?n, y composici?n de la corteza baja y del manto. GEOLOGIA DE LAS ROCAS PLUTONICAS Magma Los terremotos precedidos por erupciones volc?nicas tienen or?genes en eventos que ocurren aproximadamente a 60km bajo la superficie. Entonces podemos decir que estos movimientos tel?ricos se producen por la entrada de magma en fisuras de la corteza. Cuerpos de magma se encuentran bajo las regiones de actividad volc?nica, como el Monte Santa Helena en Oregon y en regiones de alta actividad t?rmica, como el parque Yellowstone con sus geysers, aguas termales y piscinas de lodo hirviente. El gradiente t?rmico aumenta en las capas superiores de la corteza en 10?C/km, en ares que se encuentran sobre magma, puede subir hasta 50?C/km. Formas de intrusi?n ?gnea Las rocas ?gneas plut?nicas se encuentran en capas planas o en vol?menes de configuraci?n mas complejos. Las capas de rocas ?gneas intrusivas, se extienden en dos direcciones y solamente cm o m de espesor en las otras direcciones. Estas se presentan cuando el magma se introduce en fisuras y se extiendo por kil?metros. Estas intrusiones en capas verticales a los planos de estratificaci?n son llamados diques, o de lo contrario si la intrusi?n es en forma horizontal se le denominan mantos tabulares. Tambi?n encontramos intrusiones que semejan a los mantos tabulares pero difieren a estos en que poseen una b?veda en la parte superior, este tipo de intrusi?n es llamada lacolitos. Los ge?logos estructurales ayudados por la teor?a de la mec?nica de fracturas nos pueden explicar las formas e intersecciones de los diques. Entre estas formas se encuentran los diques anillados las capas c?nicas y los grupos de diques. La estructura primaria de mayor tama?o que podemos encontrar son los batolitos . Estas formaciones son generalmente mayores a 100km?, y son enormes vol?menes de roca gran?tica que se extienden por toda la corteza terrestre. Existen otras formaciones con dimensiones menores a 100km? llamadas stocks. Clasificaci?n de las rocas plut?nicas Las rocas ?gneas est?n compuestas de un peque?o n?mero de minerales tales como: feldespatos, piroxeno, hornblenda, olivino, biotita, cuarzo y otros. Algunos de estos minerales son aliados, encontr?ndose frecuentemente juntos en

Editing My Essay Example Editing My Essay – Essay Example In 300 words or less, describe why you have chosen health sciences as a career and how you will contribute to the profession My passion to pursue a career in health science began since my childhood days, almost all careers in the field of health science have always fascinated me making it difficult to choose one. The first encounter I had with a health setting was in high school through a volunteer program, I was more interested in occupational/physical therapy. In college, I decide to take an occupational therapy course that was being offered in order to acquaint myself with knowledge about the profession to help me decide which field of occupational therapy I would specialize in. Due to my desire to become an outstanding occupational therapist, I volunteered at the Wake Forest Camp Rehab Centre where I gained more knowledge and experience in occupational therapy to help me pursue a master’s degree in occupational therapy. My character as a kindhearted person, which I inherited from my mother who has been a nurse for 15 years, is a desirable trait in this profession and determines success of a care er in occupational therapy. My desire to make a change in people’s life has been fuelled by my compassionate nature toward occupational therapy patients who need to be cared for with a lot of patient and humility. For instance, some occupational therapists just spend 15minutes with a patient then they are in a hurry to discharge him (Kramer and Hinojosa 65). This is wrong for an occupational therapist who is required to spend more time with the patients especially if they had booked an appointment or there is no queue of other patients waiting to be treated, patients should be treated warmly to ensure they are contented with treatment after visiting an occupational therapist.

Most consumers use this product for nighttime relief because of the strength of the medication and because the alcohol and antihistamine help the patient rest. How you adjusted your pricing, channel, and promotions in response to the changes in: a) Macroenvironment of the Industry: Macro-economic environment changes such as change in government regulations; taxes, demographic changes and political environment highly affect the performance of the brand. For example, decline in industry growth and rise in infaltion negatively affected all the companies (including Allround brands) in the market. The cost of goods sold became higher than the previous period and hence our bottom line took a hit. After a consistent decline in the industry profits and growth, because of the competitive nature of the industry or changes in government policies for OTC, the macroeconomic environment changed in Period 8 when it increased by almost 12% period-over-period growth. Due to anticipatory high growth, the prices of the product were marginally increased ($1) in the respective period in order to leverage the benefits of market boom. b) Consumer Behaviors: Generally speaking, m arketing revolves around people. In the words of Peter Drucker, â€Å"Marketing is the entirety of the business from the perspective of the customer.† Hence, it is imperative to understand consumer behavior in order to gain customer insights and apply it to one’s brand strategy.
