摘要：The test well MNW-1 is located in the Manewala structure of Jaisalmer basin. The Cretaceous sediments are believed to contain source rocks in this basin, the samples collected from Goru formation of upper Cretaceous sedimentary sequence were investigated using Mössbauer spectroscopy to understand the relative distribution of iron bearing minerals with depth. Iron was found present mainly in siderite, Fe2+ in clay minerals and Fe3+ in clay minerals. Large abundance of Fe3+ in clay minerals in comparison Fe2+ in clay minerals results into lower ferrous to ferric ratio in this Formation. This is an indication of poor reducing environment which is not favorable for transformation of organic matter into hydrocarbons.
