Abstract. This paper focuses on the authigenic mineralization processes acting “Tufo Rosso a Scorie Nere” (TRS), i.e. one of main pyroclastic units Vico stratovolcano (Latium, Italy). The deposits appear in general massive and made “black vitreous vesiculated juvenile scoriae”, immersed an ashy matrix lithified after zeolitization processes. minerals are chabazite phillipsite, zeolitic content ...

Zeolites are present in numerous outcrops of volcanites different ages Sicily (Italy). Some these important because they constitute the ideal genesis conditions some minerals, which represent geological indicators chemical and geothermal gradients involved during their formation. For this purpose, a group zeolites coming from areas Ionian coast Palagonia village (Eastern Sicily) was investigate...

The negative environmental impacts of Ordinary Portland Cement (OPC)-based materials, including high carbon emission, energy-intensive manufacturing process, and freshwater consumption, can be minimized by capitalizing on the concepts ancient Roman concrete. Accordingly, this study presents a pathway producing durable sustainable seawater concrete mimicking cementation Calcined clays with blend...

Abstract The purpose of this study was the conversion calcareous lignite fly ash (LFA) into synthetic zeolite by hydrothermal, fusion‐hydrothermal and hydrothermal ‐sonochemical processes. Experiments were carried out using raw washed (5 N HCl) ash. Initially, fractional factorial experimental design used to plan experiments assess process parameters such as solid liquid ratio (S/L), silica alu...

This report reviews the safety of Aluminum, Calcium, Lithium Magnesium, Lithium Magnesium Sodium, Magnesium Aluminum, Magnesium, Sodium Magnesium, and Zirconium Silicates, Magnesium Trisilicate, Attapulgite, Bentonite, Fuller’s Earth, Hectorite, Kaolin, Montmorillonite, Pyrophyllite, and Zeolite as used in cosmetic formulations. The common aspect of all these claylike ingredients is that they c...

Excessive use of nitrogen fertilizer and inappropriate fertilization designs have negative results in agricultural ecosystems, such as considerable losses through dioxide (NO2) soil leaching ammonia NH3 volatilization. In addition, climate change, with rising summer temperatures reduced precipitation, leads to production declines water shortages the soil. This review aims highlight characterist...

The detailed mineralogical and microgeochemical characteristics of polymetallic nodules collected from the Interoceanmetal Joint Organization (IOM, Szczecin, Poland) claim area, Eastern Clarion-Clipperton Fracture Zone (CCFZ, Pacific) were described in this study. obtained data applied for delimitation nodule growth generations estimation ratios (back-stripping using Co-chronometer method). met...
