Research summary

Our research aim is to determine geochemical and mineralogical compositions to evaluate the different magmatic processes at play beneath the San Luis Potosi Volcanic Field, where, lavas of widely different composition (bimodal, basalt to rhyolitic) were erupted together in both space and time, between fortyfive and point six million years ago. Data will be used for quantitative petrogenetic modelling and multidimensional techniques (that is examining five to sixteen elements in DF one and DF two type plot). The bimodal nature of the San Luis Potosi Volcanic Field in some areas and the presence of mantle and crustal xenoliths in others make the San Luis Potosi Volcanic Field interesting to evaluate simple as well as complex petrogenetic models (it is important to understand the genesis of the rhyolites relative to the more benign basalt volcanism because the silicic volcanism presents a real threat to human populations). After the exploratory geochemical and modelling work, we plan to back-up the modeling using radiogenic tracer isotopes, which will better constrain the crustal and mantle controls on lava production. Geochronology will also be employed to better constrain the relative timing of the different composition lavas that gave rise to the San Luis Potosi Volcanic Field.The current research work is carrying on with scientific collaboration of Dr. Tiffany Barry, University of Leicester, UK and Dr. Sanjeet Kumar Verma, Institute of Scientific and Technological Research of San Luis Potosi (IPICYT) Mexico.
