Geochemistry

I am going to offer you online course entitleGeochemistry.Thisis 2 credits course run online for 8 weeks and finally end with examination. This course is design for B.Sc. Geology students.This course is a basicintroductionfortheundergraduatestudentspursuing B.Sc. Geology degree. Knowledge in the field of geochemistry is expanding rapidly. Students must understand the important chemical approaches used to study the Earth. The study of geology andearth sciences has become more environmentally orientated in recent years and, as a general trend, has also become more quantitative. In turn mathematics and chemistry are an increasingly important part of environmental sciences curriculum. Recognizing both of these trends essentials of Geochemistry bring an environmental and quantitative focus to the study of Geochemistry.In my view there are two basic ways to introduce geochemistry to students.The formation of elements approaches descriptively goes through the formation ofearth and the elements in it. The present course is designed with a view to introduce a general concept and principles of Geochemistry; as per the syllabus of UGC the course emphasis thegeochemistry, which cover theIntroduction to geochemistry, basic knowledge about crystal chemistry, types of chemical bonds, coordination numbers, colloids in geological system, ion exchange and geological evidence for earlier colloids, elementary idea of periodic table along with cosmic abundance of elements, composition of planets and meteorite and along with geochemical cycle, the distribution of major, minor and trace elements in igneous, metamorphic and sedimentary rocks and elements of geochemical thermodynamics,isomorphism and isotope geochemistry. Thecoursedefinitelyprovides better understanding to students for the processes and principles involvedduring the originand evolutionof the rocks.Thecourse contains video, text, assignments,quiz, case studies, references etc andI hopeit will be useful for the geology students within and outside India.Last but not least, I highly acceptany comments, questions, or suggestion for the improvement of this course.
