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.

The central objective of
this lecture in a deeper understanding of mantle interaction. Topics include:
history of ocean basins, formation of MORBs and OIB's, mantle geochemistry,
mantle heterogeneity; slab recycling, mantle models.
This note looks at the oceans and is
an introduction to marine chemistry. The sub-topics of this lecture includes:
ocean dynamic topography, ocean temperature and salinity; oceanic circulation;
thermohaline circulation, carbon cycle, composition of sea water; variations of
sea water through time, hot vents and cold seeps, ferromanganese nodules, gas
hydrates, radiogenic isotopes in the oceans, U-disequilibrium dating and
sedimentation rates.
This book
brings together the knowledge from a variety of topics within the field of
geochemistry. The audience for this book consists of a multitude of scientists
such as physicists, geologists, technologists, petroleum engineers,
volcanologists, geochemists and government agencies. The topics represented
facilitate as establishing a starting point for new ideas and further
contributions.
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.
