During this study, we investigated the mineralogical characterization of technogenic magnetic particles (TMPs) contained in alkaline industrial dust and fly ash emitted by coal burning power plants and cement plants. The reaction of tested dust samples varied between values of pH 8 and pH 12. Their magnetic properties were characterized by measurement of magnetic susceptibility (χ), frequency d...

Beachrocks are well known as significant proxies for paleoenvironmental analysis they indicate the coastal evolution. The combination of geomorphological and archaeological sea level indicators has a contribution to paleogeographic reconstruction. In this study, we studied beachrock from Diolkos area (West Corinth canal, Greece) remnants slipway reconstruct evolution before construction until t...

Geoscientists have extensively used machine learning for geological mapping and exploring the mineral prospect of a province. However, interpretation results becomes challenging due to complexity models. This study uses convolutional neural network (CNN) Shapley additive explanation (SHAP) estimate potential locations gold mineralisation in Rengali Province, tectonised mosaic volcano-sedimentar...

 In the Northern iron-ore district of Kryvbas basin, mining deposits poor magnetic ores is underway in two quarries – Pervomaiskyi and Hannivsky. Oftentimes, their mine contours contain low-valuable or unusable magnetite-silicaceous quarzites containing ferrous slate horizons. As a result, excavated ore mass contains partly rocks various mineral chemical compositions physical technical pr...

Requisite programs soil conservation and sediment control is requires identification of areas prone to erosion and today used fingerprinting method around the world to determine the contribution of sediments transported. In this study, in order to gain optimized share of the estimated sediment resources, used of tracking feature and finally presented the map susceptibility to erosion in the Fas...

metabasites and serpentinites of the ophiolitic sequence of the gimigliano-mount reventino unit(calabria, southern italy), also known as greenstones, are employed and marketed for building and ornamentalpurposes since prehistorical times. the main topic of our research focuses on the occurrence, within the abovelithotypes, of asbestiform minerals that may be potentially harmful for human health...

This study focuses on the mineralogical and chemical characterization of Mishan Formation marls from North East Ahvaz for brick production. Mineralogical and Geochemical studies were performed by XRD and XRF methods. Major minerals in marls are quartz, calcite, dolomite and the minor minerals are orthoclase, chlorite, and muscovite. Illite and montmorillonite are also present as minor minerals ...

Along a long-term ecosystem development gradient, soil nutrient contents and mineralogical properties change, therefore probably altering soil microbial communities. However, knowledge about the dynamics of soil microbial communities during long-term ecosystem development including progressive and retrogressive stages is limited, especially in mineral soils. Therefore, microbial abundances (qua...
