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.
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. Major topics covered includes: Geochemical and
Sedimentation History of Neogene Lacustrine Sediments, Arsenic Geochemistry in
Groundwater System, Geochemistry of Hydrothermal Alteration in Volcanic Rocks,
Behaviors of Mantle Fluid During Mineralizing Processes and Potential and
Geochemical Characteristics of Geothermal Resources in Eastern Macedonia.
