Mӧssbauer Spectroscopic Study of Sub – Surface Samples of the DND#28 Well of the Jaisalmer Basin Located in Western Rajasthan, India

The Jaisalmer Basin is a pericratonic basin located on the northwest slope of the Jaisalmer Mari foundation arch that deepens southwest. With a dip angle of 30 to 50, the basin is late Paleozoic-Mesozoic and is made up of Permian rocks that unconformably rest on Proterozoic foundation. The sedimentary samples of the Pariwar Formation from the Danewala well DND#28 in the Jaisalmer Basin were the subject of the current Mӧssbauer spectroscopic investigation. The primary iron-bearing minerals include siderite, pyrite, and Fe3+ and Fe2+ in clay. When humic organic matter is present, the presence of Fe3+ in clay is more favourable, and siderite indicates that the source rocks are not as mature.
