In this study, we report a high concentration of cobalt (Co) in the rocks of Ajabgarh Group of Delhi Super-group from Nasibpur and the surrounding areas of Southwest Haryana, India, which forms a part of the North Delhi Fold Belt (NDFB). Metasedimentary and magmatic phases of the rocks contained high cobalt content ranging from 166 to 3657 ppm. The maximum concentration of cobalt (2371–3657 ppm) was observed in quartzite samples from the Nasibpur area. Cobalt enrichment in these rocks can be attributed to magmatic–hydrothermal and metamorphic fluids in relation to geological features such as shear and foliation zones, which provide a high fluid/rock ratio. Overall, the applications of cobalt are numerous and crucial. The present study warrants further extensive exploration efforts in order to assess the abundance of this valuable metal, as the global cobalt market is increasing in response to a low-carbon economy.
