The study area is located in the northeast of Iran. Miankuhi Formation is 500m thick and comprises homogeneous shales, brown granular sandstone and siltstone. In this study, 45 samples were taken from Miankuhi shales and sandstones in order to determine their tectonic origin by using a polarizing microscope. Samples were analysed by X-Ray Fluorescence (XRF) method to determine their chemical...

The paper presents research on chloride minerals of natural origin from Kłodawa (Poland), i.e., colorless, blue and purple halite as well colorless sylvite. Selected samples were studied by chemical analysis (ICP-OES, ICP-MS, titration methods) crystallographic measurements. Then, for the tested halides, was carried out using far-infrared spectroscopy. Spectroscopic studies confirmed simple way...

As Australia and the world transition to net zero emissions, hydrogen will continue grow in importance as a clean energy source, with underground storage (UHS) expected be key component of this new industry. Salt (halite) caverns are preferred option for hydrogen, given their scale, stability high injection withdrawal rates they can support. The use salt storing gas is an established industry N...

Detailed knowledge of chemical, petrographic and mineralogical compositions as well the effects applying rock powder on soil chemical properties plant production are required for classifying these materials remineralizers (SR), according to Brazilian legislation in force. This study aimed evaluate potential powders siltstone, tephrite olivine melilitite, pure or mixed, improving fertility a Cam...
