Morphology of gypsum and depositional environment. Gypsum precipitates when the salinity of solution reaches ca. five times the salinity of modern seawater (Warren, 1989). The amounts of gypsum increase vertically in the core, indicating that the brines gradually become concentrated with salt ions (Fig. 3).The Burano Evaporite Formation from the Secchia River Valley is an up to 2200 m-thick sequence composed of meter-to decameter-scale interbeds of gypsum–anhydrite and dolostones with minor halite.The deposit has been affected by a complex array of post-depositional modifications, thermal events and large-scale …Since gypsum is formed in a complex lacustrine environment controlled by changes in climate, the relationship amongst crystal morphology, trace elements …@article{osti_7230430, title = {Stratigraphy and depositional environments of Jurassic Gypsum Spring and Sundance Formations, Sheep Mountain anticline area, Big Horn County, Wyoming}, author = {Doyle, A B}, abstractNote = {The Sheep Mountain anticlinal complex between Lovell and Greybull, Wyoming, in the Bighorn basin provides exposure suitable for three-dimensional stratigraphic studies of ...

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.
