lag is a general term applied to coarse grained (> 2 mm), hard, but partially weathered rockfragments, which are concentrated at the surface through attrition of finer materials. based on morphology,mineralogy and the origin of lag from the cobar region of australia, lag may be conveniently grouped intothree broad morpho-mineralogical categories; (a) those with a rough, blocky, lithic morpholog...

We tracked the changes in water chemistry (major and trace elements, S isotope compositions, pH, Eh) and At the Sanders Lead car-battery recycling plant, near Troy, AL, identified solid “mineral” phases produced by biochemigroundwater is highly acidic (pH varies from 3 to 3.5) and carries cal processes. Theoretical geochemical modeling was high concentrations of Pb, Cd, Zn, Cu, and Fe. Pilot fi...

Abstract Gypsum crystals are found at the well perforation of observation Ktzi 202 test site for CO 2 storage Ketzin, Germany. XRD analysis confirms pure gypsum. Fluid samples before and after injection analyzed. Geochemical modeling is conducted to identify mechanisms that lead gypsum formation. The carried out with PHREEQC Pitzer database due high salinity up 5 mol per kg water. Due their sig...

Strontium isotope sourcing has become a common and useful method for assigning sources to archaeological artifacts.In Chaco Canyon, an Ancestral Pueblo regional center in New Mexico, previous studiesusing these methods have suggested that significant portion of maize and wood originate in the Chuska Mountains region, 75 km to the West [corrected]. In the present manuscript, these results were t...
