geology & geochronology (FOLDER)
Description : Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios. (Wikipedia)

geodesy, geomagnetic & geophysics (FOLDER)
Description : Geodesy is the Earth science of accurately measuring and understanding Earth's geometric shape, orientation in space and gravitational field; geomagnetic field, is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the sun; geophysics is concerned with the physical processes and physical properties of the Earth.

mineralogy & seismology (FOLDER)
Description : Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical properties of minerals and mineralized artifacts; seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies.
