Abstract	A network of fluxgate magnetometers was operated over Garhwal Lesser Himalaya Seismic Belt (GLHSB) in Uttarkashi area during 1987–1990. This study delineated a narrow conductive zone south of MCT and named as Garhwal Lesser Himalaya Conductivity Anomaly (GLHCA). Pseudo-sections of \|Z/H\| for a traverse across GLHCA implicate that the top of the anomaly is within 10 km depth and mostly of 2D nature. The tectonic formation associated with the anomaly is found to be polarization sensitive and the polarization characteristics show that the anomaly is not parallel to Main Central Thrust (MCT) but inclined by about 10°–30° in anti clockwise direction. The frequency and polarization characteristics of the induction response of GLHCA are discussed in this paper.
