Aerial photo-interpretation of the area underlain by Bandelkhand gneisses, Bijawars and Vindhyans, around Madaura and Sonrai in Lalitpur Dist. of U.P., revealed the presence of a number of lineaments. During fieldwork the lineaments were found to represent ultrabasic, basic and acidic intrusions, faultzones, lithological contacts and foliation. The drainage of the area was found to be grossly controlled by these elements. Three major trends viz. NW-SE, NE-SW and E-W are observed in the area. The first two represent shear joint system, while the latter represent release fractures. This setup is visualised to be due to N-S phase of compression.
