             abstract = "The near-vertical leakage of light gaseous hydrocarbons (HC) to 
                         the surface triggers an array of diagenetic physio-chemical and 
                         mineralogical changes in the soils and sediments overlying a HC 
                         accumulation. Over years, multi-, and hyperspectral remote sensing 
                         has been used to detect the mineralogic footprints of microseepage 
                         systems using their diagnostic spectral features in the 
                         visible-near infrared (VNIR) and shortwave infrared (SWIR) 
                         wavelengths. In practice, however, there has been ambiguities in 
                         result interpretation because the diversity and quantity of the 
                         target minerals was not well delineated by classic microseepage 
                         theory. In this article, we introduce a novel collection of 
                         alteration products induced by a microseepage system using 
                         detailed examination of 360 hand samples collected on and off the 
                         Alborz oil field in Qom area, Iran. Our Lab spectroscopy and 
                         follow-up analysis using an in-house spectral processing package 
                         named AMISA demonstrated that smectites (montmorillonite, 
                         nontronite, and likely palygorskite), chlorite, carbonates 
                         (calcite, and probably ankerite), iron oxides/oxyhydroxides 
                         (goethite, ferrihydrite, hematite, and possibly maghemite), and 
                         sulphates (gypsum and in parts jarosite) are present as diagenetic 
                         alteration products over the HC affected zones. The introduced 
                         mineralogic assemblage can provide a new insight into microseepage 
                         theory that in combination with classic model can set benchmarks 
                         for the characterization of microseepage-induced alterations using 
                         remote sensing technology.",
