Abstract Gross gamma radiation survey was carried out using Nal(Tl) scintillatorbased portable gamma ray spectrometer (PGRS) around areas of Gaonri, Dholera,Pachnota and Meghot in Mahendragarh district, Haryana. Geologically the area formspart of north Delhi fold belt comprising calc-silicate, quartz biotite schist,impure marble, quartzite and pegmatite rocks. Equivalent uranium (eU3O8)concentration in ppm was estimated in situ on a regular grid pattern of 500 m (E-W)× 1000 m (N-S) and grab samples were collected at grid locations for analyzing inthe laboratory for estimating the contents of eU3Os Raeq, ThO2 and %K. A comparisonwith the laboratory analysed grab samples for eU308 data and in situ radiationmeasurements shows a good match of the two sets of data. The in situ measurementsindicate higher concentration of eU3O8 in Chapra Bibipur in northeastern mostcorners, Maghot area in central part, Gaonri in western part and Pachnota insouthwestern part of the study area. As index to uranium favorability, U(Raeq).Th contour map (prepared using Surfersoftware with Krieging interpolation method for this grid size) based on the data ongrab samples was generated which show three major clusters of relatively high U.Thratio. The blocks delineated are enriched in sodic mineral albite which supportalbite hosted uranium mineralization potential in metamorphic rocks in Haryana.
