Course description and aims

To take petrology and geology courses, students will be required to confirm and apply the basics learned from other introductory courses. Although rocks are important resources to reveal the history of Earth, we cannot take information from them without our understanding of nature of the rocks. The teacher will explain the basics of petrology, and then students will observe rocks slices under a polarizing microscope. Students will be required to understand the feature and consisting minerals of each rock, and to judge what rocks we observe.

Student learning outcomes

[Goal] To learn the basics of geology and petrology, and relevant field in petrology. These knowledges will support to understand other classes in EPS department.
[Theme] To understand that rocks and minerals are mine of physical and chemical information for Earth and planets evolution. Throughout this class, students will get into the habit "see and think" that is the basic attitude for research activity.


Polarizing microscope, Igneous rocks, Sedimentary rocks, Metamorphic rocks, Minerals

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

To explain the contents of each class, rock observations under a polarization microscope and to sketch the rocks, and summary of the class. Before coming to class, students should read the course schedule and prepare for the topics with handouts and references.

Course schedule/Required learning

  Course schedule Required learning
Class 1 The importance of the rock observation by optical microscope, and how to use a polarizing microscope. Understanding the features of a polarizing microscope, and learning how to use it.
Class 2 Preparation of the slices of rocks 1 Cutting Understanding build process of rock slice.
Class 3 Preparation of the slices of rocks 2 polishing Understanding process of rock slice polishing.
Class 4 Observations of hypogene rocks Understanding the feature of minerals in hypogene rocks.
Class 5 Observations of volcanic rocks Understanding the feature of minerals in volcanic rocks.
Class 6 Observations of sedimentary rocks Understanding the feature of minerals in sedimentary rocks.

Assessment criteria and methods

Students will be evaluated from the intelligibility for mineral observation by microscope. The score of this class is based on the score of reports and attitudes in every class.
