Extensive Miocene volcanic activity produced basaltic and pyroclastic successions, which were penetrated by many wells in the area of Üllés-Ruzsa-Bordány, in the western and central part of the Great Hungarian Plain. The Kecel Basalt comprises primary porosity from a high proportion of vesicles and significant secondary fracture porosity, as well. Due to the significant fracture porosity, some ...

Thomsonite along with other zeolite minerals such as natrolite, mesolite, analcime and rarely stellerite in cavities and veins of mafic alkaline lavas in Hormak area, north of Zahedan, eastern Iran, is formed in there distinct habits of blocky, bladed, and waxy-growth. Chemical composition of Hormak thamsonite is reasonably comparable with those of other reported thomsonites. Si/Al ratio of the...

The Kaleybar alkaline igneous intrusion contains fine- to coarse-grained, anhedral to euhedral brown garnets. Most of the garnets are zoned. Generally, they occur in foid-bearing leucocratic rocks and the phenocrysts typically have analcime inclusions. According to mineral chemistry, the garnets of Kaleybar are Ti-andradites and melanites. The chemical zoning is characterized by a decrease in m...

The suitability of residue sand (the coarse fraction remaining from Bayer's process of bauxite refining) for constructing the surface cover of closed bauxite residue storage areas was investigated. Specifically, its properties as a medium for plant growth are of interest to ensure residue sand can support a sustainable ecosystem following site closure. The geochemical evolution of the residue s...

Abstract The quality of the Colli Albani volcanic soils has certainly contributed to vine cultivars hence name one oldest wines (i.e., Alban wine). alkali up 15 wt%, SiO2 ≤ 52 wt% and emplacement at high temperature (≤ 600 °C) are bedrock features that have deeply influenced soil-forming processes in vineyards. However, peculiar not well known. Field survey textural, mineralogical, chemical dat...

Reaction of carbon dioxide (CO 2 ) with minerals to generate stable carbonates, also known as CO mineralization, has been regarded one the most promising methods for safe and permanent storage. As a feedstock, basaltic rock gained special interest, elevating basalt carbonation efficiency reduction negative environmental impact is main challenge mineralization system development. Considering mul...

with a framework structure enclosing cavities occupied by large ions and water molecules, both of which have considerable freedom of movement, permitting ion-exchange and reversible dehydration. Because it is possible that materials with the typical physical properties of zeolites may not have framework structures, the above definition of a zeolite must be applied with caution. In order to iden...
