This means that radioactive source is associated in varying composition and depends upon the depositional environment. That is the main reason that the normal GR trends are used to interpret the subsurface sedimentary facies in the absence of 3D seismic data and well core data. 3.

It is a natural mineral that occurs in certain types of sedimentary rocks. Gypsum forms when water evaporates in mineral-rich marine soil environments. Over long periods of time, evaporation brings more minerals to the soil surface, eventually forming a solid deposit.The nodular lithofacies with wavy, irregular laminated lithofacies may show deposition in supratidal, sabkha environment and the massive gypsum lithofacies, associated with more even, laminated lithofacies may indicate precipitation in subaqueous, intertidal to subtidal environment (e.g., Schreiber et al., 1976).Sabkha. Sabkhas are hydrological settings where resurging groundwater form displactive and replacive evaporite minerals in the capillary fringe above a saline water table or in the brine-saturated muds immediately below (Warren, 2010), which are usually distributed in the uppermost interval of tidal flat environment (supratidal zone) in relatively arid climate.(i.e. transporting agent, depositional environment, energy of deposition). Depositional environment is the anticline associated with rollover structures at the border fault formed structural highs that partially isolated the faulted blocks from other depositional environments of the basin and favored the isolation of water bodies during low ...
