Objectives

This course is designed to acquire the knowledge about the origin of magma and the role of magmatic and metamorphic process in the formation of igneous rocks. This will help the students in understanding the classification of various igneous rocks and their genesis in different tectonic settings. The generation of primary basalts at mid-ocean ridges and hotspots, and the generation of all other igneous rocks (ranging from acidic to ultrabasic) from primary basalts is discussed. The laboratory is an integral part of the course and students will learn to identify common igneous minerals, rocks and textures in hand specimen and in thin section using a petrographic microscope.

Learning Outcomes

Students can identify the common rock forming minerals of igneous and metamorphic rocks in both hand specimen and thin-section. They would be able to identify key textural/micro structural features of igneous and metamorphic rocks and appreciate the significance of such features with regard to geological processes that have operated. Assign a name to an igneous or metamorphic rock on the basis of its mineralogical and textural characteristics, and appreciate the environment(s) of formation. Practical experience of rock and mineral identification in hand specimen and in thin-section using a transmitted light microscope. Ability to interpret phase diagrams relevant to igneous systems and pathogenic grids relevant to metamorphic systems on the basis of mineral assemblages recorded in the rock. Ability to make detailed and annotated Petrographic sketches from thin-section observation and to summaries the salient features and relate the chemistry of the system and environment of formation.
