Original Title:
Recent Advances in Deep Diamond Genesis
Translated title:
Recent Advances in Deep Diamond Genesis
Summary:
Diamond is perhaps the most unique mineral on our planet. Apart from its aesthetic and commercial value, it is the information it preserves for parts of our planet that are completely inaccessible that makes it scientifically priceless. Through its mineral inclusions, we travel to depths inside the earth that could not even be conceived a couple of decades ago.
Less than 1% of the global diamond production is believed to come from depths greater than 250km. However, it is the mineral inclusions of these diamonds that provide extremely valuable information about the mineralogical constitution of the deep mantle, the pressure and temperature conditions prevailing at such depths as well as the deep carbon cycle.
The first part of this diploma thesis is concerned with the geotectonic setting of diamond genesis, the main carrier rocks, and the elemental substitutions in the diamond crystal lattice that are related with its depth of formation.
The second part deals with the diversity of mineral inclusions in the diamond and their connection to specific depths of formation, depths that can reach the top of the lower mantle (more than 660km).
