Course Objective

This course aims to discuss hydrothermal systems including shallow- to deep-seated plutonic-related, volcano-plutonic to subvolcanic and volcanic-related hydrothermal systems, sub-sea-floor hydrothermal systems, and rift-associated hydrothermal systems in sedimentary basins. Basinal diagenetic brines as well as metamorphic-related hydrothermal systems will be discussed in detail. The lectures are intended primarily for exploration geologists and post-graduate students. Those who do not understand the evolution of the ore-forming systems won t appreciate the type and potential of mineralizing system already discovered. It is, therefore, analysis of mineralized systems by detailed geological, mineralogical, in particular alteration mineralogy, and geochemical studies is extremely important for an exploration geologist to use the funds efficiently in the discovery of ore deposits.

Course Contents

Week Subject Description
1 Introduction: What is a hydrothermal system Why is it important to understand the mechanism of hydrothermal systems in forming ore deposits How many of us do appreciate its significance in understanding ore-forming processes
2 Kinds of waters, which may constitute a hydrothermal solution, oxygen and hydrogen isotopic systematic and their role in understanding the nature of hydrothermal fluids
3 Definition of hydrothermal system including magmatic hydrothermal systems related to shallow and deep-seated plutonism; magmatic-meteoric hydrothermal systems related to volcano-plutonic and volcanic complexes
4 sub-sea-floor hydrothermal systems including spreading centers and island arcs; rift-associated hydrothermal systems in sedimentary basins and hydrothermal systems with metamorphic and crustal origin
5 Role of nature of hydrothermal systems on the diversification of alteration mineralogy
6 Use of alteration minerals in defining various types of hydrothermal systems and temperature/pH conditions
7 Intrusion-centered ore systems: Evolution of hydrothermal systems in intrusion centered ore fields, in particular, the role of mafic alkaline magmas in felsic-porphyry-Cu and Mo systems
8 Hydrothermal systems in metamorphic terrains This attempts to explain the pressure-temperature-time-deformation-fluid (P-T-t-d-f) characteristics of ore-forming hydrothermal system
9 Discovery of giant skarn-type Cu-Au-Zn-Ag-Co deposits in Peru in recent years once more has call the attention of exploration geologists towards long time-ignored intrusive centers close by
10 Hydrothermal systems forming VHMS deposits: Chemostratigraphy and the analysis of hydrothermal systems forming VHMS deposits and use of understanding these systems in exploring for VHMS deposits in greenstone and younger volcanic rocks will be emphasized
11 Low-Sulphidation epithermal ore-forming systems: General characteristics of alteration system and their fluids along with their model of ore formation in association with alteration are described in the world and Türkiye Hydrothermal systems and construction of exploration models. Use of recognizing hydrothermal systems in designing models for exploring hydrothermal ore deposits
12 High-Sulphidation epithermal ore-forming systems: General characteristics of high sulfidation epithermal systems and their model of ore formation are described elsewhere in the world and Türkiye
