New Course Announcement - Fall Semester 2003

Geology 590R

Mafic Magmas, Volatiles, and Ore Deposits

Instructor: J.D. Keith

Variable Credit: 1-3 hours; Tuesday 8-9 am

Course content will deal with mafic magmas (broadly basaltic), volatile contents (S, H₂O, CO₂, etc) of such magmas, and related ore deposits.

Class format will be seminar style, meeting one hour per week. Both students and participating faculty members can suggest readings for the course; then a sequence of readings will be chosen and a paper assigned to be read and discussed each week. Participants will take turns leading the discussion. Two optional field trips will also be offered as part of this course.

1 Credit Option: Attend the weekly discussion, participate in the discussion (which includes asking questions and expressing opinions), and write a summary paper on a topic of interest.

2 Credit Option: Do items required for the 1 credit option and attend one of the two optional field trips (described below).

3 Credit Option: Do items required for the 1 credit option and attend both of the field trips (described below).

Hawaii/ Oahu Field Trip – Aug 16-24

Purpose: Examine and sample fresh lavas and dikes on Oahu and Hawaii. If possible, collect mantle nodules from Koolau Ridge that are also sulfide-bearing. View and sample lava flows from Kilauea. A detailed itinerary is at: http://www.geology.byu.edu/alumni/Hawaii2003b.htm

Preliminary Itinerary:

Day	Date	Agenda
Sat	16-Aug	Fly to Honolulu; Take Aloha Air to Hilo; stay at Volcano House
Sun	17-Aug	Attend church (and other optional activities) and visit Mauna Kea Observatories
Mon	18-Aug	Examine recent volcanic features on Hawaii; sample active lava flows
Tue	19-Aug	Examine recent volcanic features on Hawaii; sample active lava flows
Wed	20-Aug	Visit olivine sand or black sand beach; fly to Honolulu; stay at Turtle Bay Resort
Thr	21-Aug	Examine Koolau Caldera and phreatomagmatic craters (possible nodule localities)
Fri	22-Aug	Examine (via snorkel) coral reefs at Hanauma Bay; visit Polynesian Cultural Center.
Sat	23-Aug	Participate in several optional activities; leave Honolulu at 10 pm
Sun	24-Aug	Arrive in SLC at 9 am

No departmental funds will be used for this trip; each participant is responsible for his or her own airfare and expenses. This is primarily an alumni trip to raise funds for the Hamblin Global Geology Fund. However, we have found the best consolidator airfares and chosen somewhat less expensive rooms for students.

Because all funds are from personal sources, spouses (and other family members) are welcome to attend and participate in any or all portions of this trip. To facilitate future trips, we are encouraging alumni to make tax-deductible donations to the Hamblin Global Geology field trip fund.

Trip Expenses (using a group discount) are shown below based on round trip, nonstop service between SLC and Honolulu (Delta) and two inter-island flights (Hawaiian Air). Car rental is based on 5-6 persons per minivan for 8 days. Trip costs below are based on the number of people sharing a room as shown.

Cost and Payment Schedule*:

Quad Occupancy:	$1390 per person
Triple Occupancy:	$1485 per person
Double Occupancy:	$1705 per person
Single Occupancy:	$2370

*this does not include food or other expenses individuals might accrue.

Initial payment of $500 is due to the Geology Department by March 5^th. Make checks payable to “BYU Geology.” Total student enrollment of no more than ten. Preference will be given to Seniors, Graduate Students, and students doing research in related areas. The deposit is refundable up until June 1^st. The remainder of the fee is due on June 15^th. Some scholarship money may be available before March 5^th payment deadline. If you have any questions, call Kris Mortenson (801-422-3919) or Jeff Keith (801-422-2189).

Keep updated on Kilauea activity by clicking here. Surface flows have been common during the last 20 years.

Yellowstone and Stillwater Pd-Pt Mine Field Trip – Sep 3-6

Purpose: Examine the role of sulfur and other volatiles in forming the magmatic and hydrothermal ore deposits (inferred) at Yellowstone National Park, the Stillwater layered mafic complex in Montana (Matt Harper’s thesis area), and the Absaroka volcanic field. Discuss the origin of the mafic (and silicic) magmas associated with these three areas.

Preliminary Itinerary:

Day	Date	Agenda
W	3-Sep	Leave on Field Trip at 5:30 PM from ESC East Lot; stay in Rexburg
Th	4-Sep	Yellowstone Nat. Park – Bimodal Volcanism &Hydrothermal Activity; Stay in Red Lodge
F	5-Sep	Visit Stillwater Complex, Underground Pd-Pt Mine Tour, Mill Tour; Stay in Red Lodge
S	6-Sep	Return via Beartooth Pass and Absaroka Volcanics; arrive in Provo at midnight

Departmental funds will be used for this trip; however, each student is responsible for their own meals. This trip will be combined with students from Geology 460 (and perhaps other classes).

Be advised that if a student attends the Yellowstone field trip, he or she will miss 2 days of Fall semester classes during the first week of classes (during the add/drop period).
