Intergrated Airborne Gammaray Spectral and Satellite Data Analysis for U and REE Mineralisation — A Case Sudy from North Sagobandh Area, District Sonbhadra, Uttar Pradesh, India

Petrogenesis and Rb-Sr Isotopic Characteristics of Paleo-Mesoproterozoic Mirgarani Granite Sonbhadra Uttar Pradesh India: Geodynamics Implication for Supercontinent Cycle

“…The Son-Narmada South Fault (SNSF) and North Fault (SNNF) cause radiometric breaks in the radio-geochemical images based on airborne gamma-ray spectrometric data in the Son-Valley area, where the Mahakoshal group of volcano-sedimentary rock have deposited in the rift valley known as Son Valley. These faults have NE-SW, East-West, and ENE-WSW trending faults [20] . Mirgarani granite is coeval to the granites in Bihar Mica Belt (BMB) around the Bhallupahari-Nerupahar, Hazaribagh area dated 1590 ± 30 Ma [75] .…”

“…Three sets of lineaments were observed: NE-SW, ENE-WSW, and east-west. The migmatite complex hosts several uranium occurrences in Anjangira-Deohar and north of Sagobandh village (Figure 2a) [20][21][22][23] . The Dudhi Group unconformably overlies the Archean basement and starts with transition sediments with oligomictic quartz pebble meta conglomerates overlaid by Metamorphites, Migmatite Complex, and younger intrusive granites, of various ages Mafic Granulites, and syenites.…”
