This
note covers all aspects of molecular biosignatures, such as their pathways of
lipid biosynthesis, the distribution patterns of lipid biosynthetic pathways
with regard to phylogeny and physiology, isotopic contents, occurrence in modern
organisms and environments, diagenetic pathways, analytical techniques and the
occurrence of molecular fossils through the geological record.

This note covers the following
topics: Geochemical Fundamentals, Low Temperature Geochemistry: The hydrologic
cycle and sedimentary systems, High Temperature and Planetary Geochemistry.
This note explains the
following topics: acid or base and electrochemical concepts, aqueous
geochemistry and solid-water interactions with an emphasis on ground water,
chemical weathering, mineral thermodynamics and redox (Eh-pH) diagrams and their
applications to soil and mineral stability and ground water chemistry, modeling,
environmental geochemistry and isotopes applied to groundwaters.
This note describes the following topics:
Physics of the Nucleus and Radioactive Decay, Nucleosynthesis, Geochronology,
Radiogenic Isotope Geochemistry, Cosmogenic Isotopes in Geochronology, Fission
Track Dating, Isotope Cosmochemistry, Stable Isotope Geochemistry.
This course note introduces students to the basic concepts of
Medical Geology/Geochemistry. Medical Geology or Geochemistry is the study of the
interaction between abundances of elements and isotopes and the health of humans
and plants. Topics covered includes: Classification of Elements, Elemental Link
Between Geosphere and Biosphere, Essential and Non-essential Elements with
Reference to Human Health, Selection of Elements for Report and
Presentation,NORM (Naturally Occurring Radioactive Material), TENORM, MIT-EAPS
Neutron Activation Analysis Laboratory - Hands on Experience and Dust Storms.
