Research on carbonatites and associated alkaline rocks from India

In the field (Central India)

In December 2015, research scientist Lukáš Ackerman was involved in the field work on carbonatites and associated alkaline rocks (phonolite, trachyte) in Middle India (localities Amba Dongar and Panwad-Kanwat) within the framework of research project of the Czech Geological Survey. These sites are located on the northernmost part of world known Deccan flood basalts erupted on the Cretaceous-Tertiary boundary. The collected samples will be for the first time analyzed for the concentrations of platinum-group element as well as osmium isotopic compositions in order to provide insights to carbonatite melt sources and possible role of parental melt crustal contamination.
