Syllabus

Module 1 :

Module 1: Types and classification of ore deposits. Crustal evolution and metallogeny throughout geological time scale.
Module 2: Igneous ore forming processes: partial melting, crystal fractionation and liquid immiscibility. Mechanisms for chromite mineralization, Ni-Cu sulfide deposits, PGE mineralization and Fe-Ti oxide deposits in anorthositic rocks.
Module 3: Formation of magmatic aqueous phase, composition and characteristics of magmatic-hydrothermal solutions. Pegmatite and granite-related ore forming processes. Models for formation of porphyry Cu, Mo, and W deposits, skarns deposits and near-surface epithermal Au-Ag-(Cu) deposit. Metamorphism its causes and effects.
Module 4: Ore fluids, physico-chemical aspects related to metal transport (and deposition). Sources of ore fluid and metals through fluid inclusions and stable isotopes. Modern sea floor hydrothermal deposits: mineralogical, geochemical and genetic aspects of SEDEX and VMS ores deposits.
Module 5: Sedimentary/surficial ore forming processes: clastic sedimentation and heavy mineral concentration, chemical sedimentation of banded-iron formation, supergene enrichment of Cu and other metals, laterite deposits formation.

Course Objective

1 .

To provide the knowledge to identify the association between rock types and metallogenesis and evaluate the patterns of ore distribution.

2 .

To impart in-depth knowledge of magmatic ore deposits and analyze its enrichment mechanisms.

3 .

To introduce the concept of magmatic-hydrothermal interplay and identify the mineral enrichment involved in such process.

4 .

To impart knowledge on sedimentary ore deposits and explore the relation between paleoclimate and metallogeny.

Course Outcome

1 .

CO 1: Identify types of ore mineralization and evaluate the pattern of ore distribution through time.

CO2: Understand the process of formation of igneous ore deposits.

CO3: Decipher the mechanisms for formation of magmatic-hydrothermal ore deposits.

CO4: Examine the present day analogue for seafloor hydrothermal ore deposits.
