Study of Lineament Patterns of the PGE-bearing Mafic-Ultramafic Rocks of Madaura area, Bundelkhand Craton, Central India using Remote Sensing Data
The Archean Bundelkhand craton (Figs.1.1.a and 1.1.b)occupies nearly 29, 000 sq km in the form of a large semi-circular outcrop in parts of central Indian shield. It dominantly comprises granitoids (2.5-2.2 Ga), metasupracrustals (up to 3.3 Ga), giant quartz veins and younger mafic intrusives. The PGE-bearing mafic-ultramafic rocks are exposed in sporadic and low lying areas in the southernmost fringe of the Bundelkhand craton. These rocks are located in and around Madaura, Dangli, Ikonakhurd, Rajola, Gorakalan, Purani Pindar, Hanumatgarh, and Siron area, Lalitpur district, Uttar Pradesh, India with regional spread of about 200 km2 while the cumulative outcrop area of only～50 km2, and do not reveal their contact relationship with the host granitoids. The exposures are scanty, scattered, partly covered by alluvium and covered under thick forest covers at places. Hence, for a synoptic view of the eight outcrops in the regional scale, the use of remote sensing data has been of tremendous help. The remote sensing study in the present work has been carried out using the Survey of India toposheet (54L/15), IRS-1D hybrid data of May, 2003 (PAN: 10:04:2003 & 02:05:2003; LISS-Ⅲ: 02:05:2003), LANDSAT TM data (Path-145, Row-43; 20:11:2000)and the Google Earth images (2008).
