COURSE DESCRIPTION

This is an independent geophysical fieldwork lasting 4-6 weeks during long vacation at the end of the third year. 300 level undergraduates students are trained to acquire, process and interpret geophysical data based on each of the geophysical methods they have been taught in the school. A written report on this exercise shall be submitted at the beginning of the second semester of the fourth year.

COURSE OBJECTIVES

The objectives of this course are:

  1. GEOLOGICAL:
  • Location of outcrops and description
  • Strike and dip measurement of outcrops
  • Plotting strike and dip on the field map
  • Assigning a tentative field name to outcrops studied
  1. GEOPHYSICAL:
  • Establishment of geophysical traverses
  • Study of subsurface geology and structure
  • Improvement of existing geologic boundaries of rock types
  • Study of the groundwater and mineral potentials of the study location

COURSE LEARNING OUTCOMES / COMPETENCIES

Upon successful completion of this course, the student will be able to:

(Knowledge based)

  • The student will understand the relationship between geophysical traverses and existing geology
  • Instrumentation trouble shooting to detect malfunctioning
  • Position location on the field using compass-chinometer, global positioning system(GPS) and topographic map

(Skills)

  • Students can carry out geophysical survey independently with little supervision
  • The students can also process and interprete the acquired data.
  • Understanding of the fundamental of geophysical report writing

GRADING SYSTEM FOR THE COURSE

This course will be graded as follows:

Geological report:                   30%

Geophysical report:                 70%

TOTAL                                  100%

 

GENERAL INSTRUCTIONS

Attendance: It is expected that every student must be on the field and participate effectively in all the exercises. Attendance records are kept each day to determine each person participation in the field work. In case of illness or other unavoidable cause of absence, the student must communicate as soon as possible with any of the instructors, indicating the reason for the absence. A maximum attendance and participation of 60% is expected from a student to be eligible for grading on the field.

Academic Integrity: Violations of academic integrity, including dishonesty in assignments, stealing, fighting or other unethical behaviours are prohibited. You are not allowed to make copies of another person’s work and submit it as your own, that is plagiarism. All the cases of academic dishonesty will be reported to the university management for appropriate sanctions in accordance with the guidelines for handling student misconduct  as spelt out in the student handbook.

Assignments and Group Work: students are expected to submit assignments as scheduled. failure to submit an assignment as at when due will earn you zero for that assignment only under extenuating circumstances, for which a student has notified any of the instructors in advance with late submission of assignment be permitted.

 

Code of Conduct during Field Work

(In the Hostel/Hotel)

Students should turn off their cell phones during lectures. Students are prohibited from engaging in other activities (such as texting, watching videos etc. during lectures. A register is marked at 10pm each night to ensure that every student is around. Going out at late hours is forbidden or prohibited except on emergency cases where a student took ill and had to be rushed to the nearest hospital. This is normally done with the consent of any of the instructors. All the rules and regulations for a successful field work as outlined by the field co-ordinator must be strictly adhered by both students and staff members.

 (On the Field)

Late coming to the field by the students is not allowed. Playing on the field while others are working will attract severe sanctions and in extreme cases, the students may be asked to return to school, this means automatic carry-over of the course to another year

Course Synopsis

This course is the first course in numerical analysis designed for students in mathematics, physical sciences, engineering, mineral and earth sciences. The focus of the course is to equip students with basic useful skills to solve numerically both theoretical and empirical problems leading to linear and nonlinear equations. Topics to be covered include numerical solution of algebraic and transcendental equations; curve fitting; error analysis; interpolation and approximation; zeros of non linear equations in one variable; system of linear equations; numerical differentiation and integration.
