Course Description

In the resource engineering, data acquirement and observation in the field are essential skills. For learning these knowledge, two field experiments are conducted; geological and geophysical surveys.

Grading

Evaluation based on reports and presentations. Details will be explained at the beginning of class.

Course Goals


Geological Survey
Students can understand the relationship between the geology and topography by field observations, and also become familiar with the observation of the geological outcrops from the view point of resource geology. In addition, they can explain how the topography and geology are deeply related each other, and obtain the basic geological information, such as strike, dip, rock type (mineral species) in the field observation (measurement).
Geophysical Survey
Students carry out the field training and data analysis of seismic refraction survey and electrical resistivity exploration. In the field training, they learn deployment of geophones for land seismic survey, together with arrangement of current/potential electrodes for electrical survey. In addition, they can understand the vibration at seismic source wave and recording method of the seismic wave, together with the transmission of electric current and the measurement of potential. In the data analysis, students can deeply learn the knowledge about the estimated physical quantity from the recorded data, and also understand the imaging method for underground structure.

Course Topics

Theme Class number of times Description
Topographic Analysis (Geology) 2 The topographic analysis method is lectured as a pre-study of geological field trip, then students carry out the analysis by using topographic maps and aerial photos of the excursion destination.
Field Excursion I, II (Geology) 6 Students observe the outcrops in the field, and compare the real geological structure with the results done as the exercises. Two excursions on the different locations are conducted.
Presentation 2 Students make presentations what they learned in the excursion and analysis.
Seismic Survey (Geophysics) 2.5 Along the Kamo river side, the seismic refraction survey is conducted. The data acquired is analyzed using the "stripping method", and used for estimating the subsurface structure based on the seismic wave velocity.
Electrical Resistivity Survey (Geophysics) 2.5 Along the Kamo river side, the electrical resistivity survey using the Wenner array is conducted. The data acquired is analyzed , then students learn the theoretical basis of this method together with a way for estimation of subsurface resistivity structure.
