Abstract

The Bundelkhand Granitic Complex of central India contains inclusions of Archaean volcanic and sedimentary rocks and orthogneisses, some of which are 15 km by 6 km in size, Earlier workers considered that these inclusions belong to two distinct lithostratigraphic formations separated in time by a migmatization event. Our new data suggest that the migmatization event post-dated all of the volcanic and sedimentary rocks and hence the two-fold stratigraphic subdivision is not viable. Further, intrusion of orthogneisses resulted in an increase in grade of metamorphism in some volcanic and sedimentary rocks specifically near the contact.
