The Variscan high-grade metamorphic basement of northern Sardinia and southern Corsica record lower Carboniferous anatexis related to post-collisional decompression the orogen. Migmatites exposed in Punta Bianca locality (Italy) consist quartz + biotite plagioclase K-feldspar orthogneisses, garnet cordierite-bearing diatexite metatexites, derived from metasediments. Field evidence, petrographic...

Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. This study evaluated a novel approach for buffering subsurface pH that relies on the use of silicate minerals as a long-term source of alkalinity. A screening methodology based on thermodynamic considerations and numerical simulations was developed to rank silicate minerals acc...
