Tracy, and Brent E. Owens. New York: W. H. Freeman and Company, 2006. The Blackboard site for this course provides essential resources for this course. Check your Towson e-mail account daily for possible course-related announcements. 1 Course Objectives: Upon successfully completing the course, students should be able to explain and apply knowledge and skills central to the domain of professional geologists, including: . formation and modification of magma . differentiation, fractional crystallization, partial melting . primary textures of igneous rocks . determination of crystallization history of an igneous rocks . intrusive and extrusive magmatic features . eruptive styles of volcanoes as function of lava composition & viscosity . interpretation of binary and ternary phase diagrams . fabrics and compositions of metamorphic rocks . quartz optical microstructures . formation and kinematic interpretation of mylonites . connections between crystalline rocks and plate tectonic margins . crystalline rocks of the Maryland Piedmont geology . analysis of metamorphic rocks to determine their petrologic histories . writing and presenting an accurate report on a crystalline rock COURSE INFORMATION AND POLICIES Grading: The Grade Center in Blackboard will maintain a running weighted Letter average of your scores. Course grades will be assigned according to Cumulative % Grade breakdown shown at right: 94-10 A 90-93.9 A- 87-89.9 B+ 84.0-86.9 B Please note: A student must receive a course grade of at least a 80.0-83.9 B- 77.0-79.9 C+ middle C (73.0%) to fulfill this requirement of the Geology major. 73.0-76.9 C 70.0-73.0 D+ 60.0-69.9 D Below 60 F Your course grade will be based on the following distribution (approximate): Assignment or Assessment: % of total grade Laboratory Assignments 30 Homeworks, etc.: 20 Igneous Case Study 25 Piedmont Project 25 TOTAL 100 Lectures: Students are expected to attend every class and be prepared to discuss the assigned reading. Students in this class are expected to behave in a professional manner befitting their attendance at university in preparation to become working geoscientists, including the following: be present and attentive for the entire class period; demonstrate preparation for that day’s class by bringing lecture PDF’s, if available, answering questions, and asking substantive questions; turn in completed assignments on time; participate in class discussions and activities; and respectfully listen to the instructor and to other students. 2 Persistent distracting and disrespectful behavior (texting, tardiness, talking, chewing gum, sleeping, etc.) will deduct points from your course grade and/or lead to dismissal from class. Labs: Laboratory activities in this course synthesize lecture and lab skills and will include identification of rocks in hand samples and in thin section. Labs will usually be begun on Monday and turned in the next Monday. Lab work in the course may require work outside of class. When the classroom is free, you may use this room to work quietly on assignments, but distracting activities (loud talking, computer games/videos, etc.) are not to be conducted in the room. Late work is not accepted without documentation of a student’s serious personal or medical emergency. Although students are encouraged to exchange ideas, your lab work is expected to be your own. Collusion on lab work will result in zero credit to all involved parties. Homeworks, etc.: The purpose of these assignments is to encourage students to keep up with the lecture material. These will be assigned throughout the semester and may be handed in either in class or on-line through Blackboard; specific requirements will be described later in the course. Field Trips: Field trips will be conducted during class period (weather permitting) and will require you to either travel in your own vehicle or car-pool with another student; if you have serious concerns about this requirement, contact the instructor as soon as possible. Field trips will involve detailed observations of rocks and other field skills; no pets, pals, smoking, etc., are allowed on the trips. All students must sign the Field Trip liability waiver required by the University. Field trip cancellation due to inclement weather will be announced via e-mail to your Towson account as early as possible; unless otherwise noted in the cancellation announcement, we will meet in the classroom. o Field Trip 1 (3/7): Ellicott City Granodiorite and Baltimore Mafic Complex: magmatic contacts, xenoliths, flow foliation, layered intrusion o Field Trip 2 (5/2): Setters Schist and Cockeysville Marble, Hunt Valley: amphibolite facies metamorphism, index minerals Igneous Case Study and Piedmont Project: In lieu of traditional exams, students will undertake two projects requiring mastery of both lecture and laboratory concepts, each involving observation, description, interpretation, application, and synthesis. The first project will be on an igneous rock (hand sample + thin section), with a write-up illustrated with labeled photomicrographs summarizing your results. The second project will be on a metamorphic rock (hand sample + thin section) from the Maryland Piedmont and will involve either writing a paper and then giving a professional-quality PowerPoint presentation or designing an interactive web page that presents your observations and interpretations. More details will be provided later. Students with Special Accommodations: This course is in compliance with Towson University policies on students with special accommodations. Most course materials are provided on-line via Blackboard. Students requesting note-takers and other accommodations must notify the instructor as early as possible in the semester with the proper paperwork; the availability of a note-taker is dependent upon another student in the class volunteering to take notes. Withdrawal Deadline: The deadline to withdraw from this course with a “W” is April 30th. You may not repeat this course more than once without permission of the Academic Standards Committee. 3 .

  • History of Geology
    FEBRUARY 2007 PRIMEFACT 563 (REPLACES MINFACT 60) History of geology Mineral Resources Early humans needed a knowledge of simple geology to enable them to select the most suitable rock types both for axe-heads and knives and for the ornamental stones they used in worship. In the Neolithic and Bronze Ages, about 5000 to 2500 BC, flint was mined in the areas which are now Belgium, Sweden, France, Portugal and Britain. While Stone Age cultures persisted in Britain until after 2000 BC, in the Middle East people began to mine useful minerals such as iron ore, tin, clay, gold and copper as early as 4000 BC. Smelting techniques were developed to make the manufacture of metal tools possible. Copper was probably the earliest metal to be smelted, that is, extracted from its ore by melting. Copper is obtained easily by reducing the green copper carbonate mineral malachite, itself regarded as a precious stone. From 4000 BC on, the use of clay for brick-making became widespread. The Reverend William Branwhite Clarke (1798-1878), smelting of iron ore for making of tools and the ‘father’ of geology in New South Wales weapons began in Asia Minor at about 1300 BC but did not become common in Western Europe until Aristotle believed volcanic eruptions and nearly 500 BC. earthquakes were caused by violent winds escaping from the interior of the earth. Since earlier writers had ascribed these phenomena to The classical period supernatural causes, Aristotle's belief was a By recognising important surface processes at marked step forward. Eratosthenes, a librarian at work, the Greek, Arabic and Roman civilisations Alexandria at about 200 BC, made surprisingly contributed to the growth of knowledge about the accurate measurements of the circumference of earth.

  • 2. Petrology and Mineralogy
    2. Petrology and Mineralogy In the period from 1999 to 2002, many studies on petrology and mineralogy have been made by Japanese earth scientists as well as the previous period. Significant progress has been made at the Japanese-USA cooperative studies on Hawaiian volcanoes (Naka et al., 2000; see section VII of this report), including deep-sea survey with the submersible "Shinkai 6500", the world's most advanced deep-sea probe. Major part of the outcome was published as a monograph (Takahashi, E. et al., 2002), including petrological and geochemical studies on products collected by the deep-sea survey (Kaneoka et al., 2002; Sherman et al., 2002; Shinozaki et al., 2002; Tanaka et al., 2002) and melting experiments on basalt+peridotite (Takahashi, E. and Nakajima, 2002). Other studies on the Hawaii project were appeared as individual papers (e.g., Lipman et al., 2000). Research on Unzen volcano also progressed significantly after its eruption of 1990-1995 (Chen, C. H. et al., 1999; Kusakabe et al., 1999; Nakada and Motomura, 1999; Sato et al., 1999; Tateyama et al., 2002; Watanabe, Ko. et al., 1999). At the volcano, international scientific drilling project (Unzen volcano Scientific Drilling Project) is going on (Sakuma and Nakada, 2002; Sakuma and Saito, 2000; Uto et al., 2000; see section VII of this report) and many publications will be appeared in the next period. Research on subduction-zone magmatism around Japan was made energetically. As for Northeast Japan, spatial distribution of volcanoes was noticed (Umeda et al., 1999), and a new concept of "hot fingers" in the mantle wedge was proposed (Tamura, Y.

    REVIEWS OF GEOPHYSICS, VOL. 26, NO. 3, PAGES 370-404, AUGUST 1988 Magma Genesis, Plate Tectonics, and Chemical Differentiation of the Earth PETER J. WYLLIE Division of Geolo•7icaland Planetary Sciences,California Institute of Technolo•Ty,Pasadena Magma genesis,migration, and eruption have played prominent roles in the chemical differentiation of the Earth. Plate tectonics has provided the framework of tectonic environments for different suites of igneousrocks and the dynamic mechanismsfor moving massesof rock into melting regions.Petrology is rooted in geophysics.Petrological and geophysicalprocesses are calibrated by the phase equilibria of the materials. The geochemistry of basalts and mantle xenoliths demonstrates that the mantle is hetero- geneous.The geochemical reservoirs are related to mantle convection, with interpretation of a mantle layered or stratified or peppered with blobs. Seismic tomography is beginning to reveal the density distribution of the mantle in three dimensions,and together with fluid mechanical models and interpreta- tion of the geoid, closer limits are being placed on mantle convection.
