Gold Country
The Gold Country (also known as Mother Lode Country) is a historic region in the northern portion of the U.S. state of California, that is primarily on the western slope of the Sierra Nevada. It is famed for the mineral deposits and gold mines that attracted waves of immigrants, known as the 49ers, during the 1849 California Gold Rush. History When gold was first discovered in 1848 many people came from all over the world to find gold. The migration into California brought diseases and violence. There were 500 mining camps of which 300 are still undiscovered as of today. There was 400 million dollars in gold mined between 1849 and 1855. In 1942 most of the mines shut down due to World War II. The transportation in Gold Country grew rapidly due to the Gold Rush. The first railroad in California ran through Gold Country. There were 250 different stage coach companies formed by 1860. Major Events Per County: * Amador County – At the time of the Gold Rush the Kennedy Mine was ...

Master Of Science
A Master of Science ( la, Magisterii Scientiae; abbreviated MS, M.S., MSc, M.Sc., SM, S.M., ScM or Sc.M.) is a master's degree in the field of science awarded by universities in many countries or a person holding such a degree. In contrast to the Master of Arts degree, the Master of Science degree is typically granted for studies in sciences, engineering and medicine and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, earning a Master of Science degree typically includes writing a thesis. The Master of Science degree was first introduced at the University of Michigan in 1858. One of the first recipients of the degree was De Volson Wood, who was conferred a Master of Science degree at the University of Michigan in 1859. Al ...

Mining Geology
Mining geology is an applied science which combines the principles of economic geology and mining engineering to the development of a defined mineral resource. Mining geologists and engineers work to develop an identified ore deposit to economically extract the ore. Mining geology is the process of exploration and exploitation of ore or economic minerals from the earth.it is also called "winning"the ore from the earth. See also * Ore genesis * Prospecting * Mineral exploration ** Exploration geophysics ** Geochemistry ** Remote sensing * Mining * Industrial mineral Industrial resources (minerals) are geological materials which are mined for their commercial value, which are not fuel (fuel minerals or mineral fuels) and are not sources of metals (metallic minerals) but are used in the industries based on th ...

Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxford a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrology
Petrology () is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together because they both contain heavy use of chemistry, chemical methods, and phase diagrams. Sedimentary petrology is, on the other hand, commonly taught together with stratigraphy because it deals with the processes that form sedimentary rock. Background Lithology was once approximately synonymous with petrography, but in current usage, lithology focuses on macroscopic hand-sample or outcrop-scale description of rocks while petrography is the speciality that deals with microscopic details. In the petroleum industry, lithology, or more specifically mud logging, is the graphic representation of geological formations being drilled through and drawn on a log called a mud log. As the cuttings are circulated out of the borehole, they are sample ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

German American
German Americans (german: Deutschamerikaner, ) are Americans who have full or partial German ancestry. With an estimated size of approximately 43 million in 2019, German Americans are the largest of the self-reported ancestry groups by the United States Census Bureau in its American Community Survey. German Americans account for about one third of the total population of people of German ancestry in the world. Very few of the German states had colonies in the new world. In the 1670s, the first significant groups of German immigrants arrived in the British colonies, settling primarily in Pennsylvania, New York and Virginia. The Mississippi Company of France moved thousands of Germans from Europe to Louisiana and to the German Coast, Orleans Territory between 1718 and 1750. Immigration ramped up sharply during the 19th century. There is a "German belt" that extends all the way across the United States, from eastern Pennsylvania to the Oregon coast. Pennsylvania, with 3.5 mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
