The present study investigates the effect of β-hemihydrate gypsum (HG) dosages on mechanical and microstructural performance cemented paste backfill (CPB) produced from sulphide-rich mine tailings using NaOH-activated slag (NAS) as major binder. X-ray diffraction (XRD), scanning electron microscopy (SEM) mercury intrusion porosimetry (MIP) analyses were carried out to elucidate mineralogical co...

study of soil and plant relationships is nessesery for ecological- based and appropriate management. the objective of this study is to determine the influence of edaphic properties on haloxylon persicum growth and also, indentifing growth limiting soil properties for saxaul. the study was performed through the stratified random sampling and 3 sites were selected as follow: planted strong saxaul...

Subaqueous gypsum (CaSO4·2H2O) crystals are relatively common in epithermal systems where sulfide ore deposits present. The Giant Geode of Pulpí (Almería, SE Spain) hosts some the largest (up to 2 m length) subaqueous discovered date. Here, we present first U-series ages its and reconstruct oxygen hydrogen isotopic composition (δ18O δ2H) paleo-aquifer from which formed by using stable isotopes ...
