Geological Mapping Course - Syllabus (8-28th Sep 2014)

Prof. Masayuki Komatsu

Geological Mapping Course 8-28th September, 2014 (Credit 4) only for geology students of Gorontalo State University (semester 5 and higher).

Instructor: Prof. Masayuki Komatsu (Ehime University)

8 days consisting of 16 classes are for lecture and desk work in the room and 8 days of 16 classes are for training in the field or outside the room. Duration of 1 class is 90 min, and there are 2 classes in the morning. First class will start in the morning at 08.30 and end at 10.00, with a break for 20 min. And second class will start at 10.20 and end at 12.00.

Lectures and desk works (8 days)

• Introduction to geology and geological mapping.
• Topographic map: what topographic map is? Some exercises*
• How to read topographic map: Imaging the feature of the map and draw cross-section of topographic maps.
• Intersection of a boundary plane with topography.
• A method to plot a boundary plane on a topographic map using the attitude in an outcrop.
• Exercises: drawing a boundary plane on map.
• Apparent dip problem:
• Case 1: Determine true dip from strike + attitude of an apparent dip.
• Case 2: Determine strike and dip from two apparent dips
• Case 3: The three point problem
• Methods of geological mapping ; field equipments and traversing.
• What you observe in the field: sedimentary rocks and stratigraphy
• Unconformity and the geological cross-section
• Faults and folds
• Description of strata and rocks (some more detail)
• Igneous and metamorphic rocks
• Geological mapping, making a route map and an areal map
• Geological report
• Introduction to the geology and geological evolution of Sulawesi.
• Remarkable geo-sites around Gorontalo: carbonate rocks and their depositional system as evidence of rifting.
• Active faults and collapsed structures : evidence of rapid uplifting

Field training (8 days)

• How to measure a distance in the field - a method of pacing
• Measurement of your pace and double paces in campus.
• Measurement of campus roads and making a campus map using your double paces and compass-clinometer.
• How to use copass-clinometer, and how to measure the attitude of planes and line in the field, including the basic training of geological mapping.
• Geological excursion to North Gorontalo (or to Olele depending on conditions) to have a look of carbonates, Miocene volcanic rocks and sedimentary strata.
• Geological mapping (1) along the bay-pass road around a village in Southeast Gorontalo to Bone river: Miocene volcanic rocks, granite, conglomerate and carbonates. Making a fair copy map (the same as in the case 2 to 5)**
• Geological mapping (2) along Laksamana Martadinata street and along a path in the mountain: carbonates and volcanic rocks.
• Geological mapping (3) along the North foot of the Southern mountain range in Gorontalo: granite, corbonates and superficial sediments with normal faults.
• Geological mapping (4) Traverse over the ridge of the Southern mountain range in Gorontalo: from Dumbe to Kayubulan area.
• Geological mapping (5) Traverse over the ridge from Donggala to Tontayu.
• Option

Notice: The results of exercises* and all the fair copy of maps** that you have made are required to submit after the end of this course.
