**8. Conclusion**

The rock types exposed in Nakora Ring Complex were classified into three major lithological divisions: basalt and rhyolite as first phase, second phase of granites of different colors and third and last phase magmatism of dykes of fine-grained granites and rhyolites. Based on petrographical observations, it is suggested that rhyolites show ophitic, sub-ophitic, porphyritic, granophyric, glomeroporphyritic, aphyritic, spherulitic, perlitic, hypidiomorphic, granophyric and microgranophyric textures. These textures have close similarities with A-type, anorogenic and withinplate granitoids as early reported by MIS rock-types behave. The volcano-plutonic rock associations and physio-chemical characteristics showed that during complex geological processes, the rock types of the Nakora Ring Complex were formed. Volcanic vent (approx. 40 m wide and semicircular to elongated shape) and sudden change pathways of Luni River advocates the relationship between tectonism and volcanism. Magmatic growth, phase petrology and geodynamic indicated that the studied areas in the NW Indian shield belonging to the MIS extension could be developed under the plume-related hot spot extension model.
