Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt.
History
The term geochemistry was first used by the Swiss-German chemist Christian Friedrich Schönbein in 1838. In his paper, Schönbein predicted the birth of a new field of study, stating:
The field began to be realised a short time after Schönbein's work, but his term - 'geochemistry' - was initially used neither by geologists nor chemists and there was much debate over which of the two sciences should be the dominant partner. There was little collaboration between geologists and chemists and the field of geochemistry remained small and unrecognised. In the late 19th Century a Swiss man by the name of Victor Goldschmidt was born, who later became known as the father of geochemistry. His paper, Geochemische Verteilungsgesetze der Elemente, on the distribution of elements in nature has been referred to as the start of geochemistry. During the early 20th Century, a number of geochemists produced work that began to popularise the field, including Frank Wigglesworth Clarke who had begun to investigate the abundances of various elements within the Earth and how the quantities were related to atomic weight. The composition of meteorites and their differences to terrestrial rocks was being investigated as early as 1850 and in 1901, Oliver C. Farrington hypothesised although there were differences, that the relative abundances should still be the same. This was the beginnings of the field of cosmochemistry and has contributed much of what we know about the formation of the Earth and the Solar System.

Geochemical Affinity
The formation of minerals is controlled by the geochemical affinity between elements and the ability of these elements to bond and start the process of crystallization of a certain mineral.
This affinity was first determined by Goldschmidt, who observed the elements of the periodic table and individualized them into 4 main groups: lithophiles, siderophiles, chalcophiles, and atmophiles. This allowed the possibility to know what would be the expected behavior of a certain element when present in a geological environment, whatever it may be.
This classification represents the affinity of the elements to bind to form crystalline silicate structures (for the group of lithophiles), to bind to sulfur (such as chalcophile), to show affinity with metallic iron (siderophiles) or to present in the g...

This classification represents the affinity of the elements to bind to form crystalline silicate structures (for the group of lithophiles), to bind to sulfur (such as chalcophile), to show affinity with metallic iron (siderophiles) or to present in the gaseous state (atmophiles).
This study and classification are important, as they identify the elements that are most likely to be found in the crystalline structures of these mineral classes. However, it must be used with caution, since it represents the greatest affinity of an element when it’s about to bond, but it can be found in another type of structure.
For example, Fe obviously has a higher siderophile affinity but is commonly found in biotite, pyroxene, and olivine structures, where it is found as lithophile affinity. In addition to being able to present itself in sulfide structures such as pyrite or chalcopyrite, showing chalcophile affinity in this case.
So, it is important to know the greater affinity of a particular element in relation to the type of bond that it has a preference for making and which mineral it has a preference for forming, because it is thus possible to imagine the behavior of this element during a geological process and assist in the interpretation of how a particular rock was formed, in addition to being very important for understanding the partition coefficient and mobility of elements that will be discussed in further videos.
