Few published analyses of feldspar pairs give concordant temperatures, probably because small errors in composition strongly affect the calculated temperatures. However, if the compositions of coexisting feldspars are allowed to vary within expected analytical error, three concordant temperatures can be calculated for feldspar pairs that were close to being in equilibrium.

Abstract. By 2050, the world''s population will have reached 9 billion. To feed that many people, soil fertility will have to be maintained artificially. All fertiliser materials depend on a geological resource: nitrogen (N) fertilizer production needs fossil fuels, and both phosphate (P…
2017-3-1 · The leaching kinetics of K-feldspar in H 2 SO 4-CaF 2 system with the assistant of ultrasound was investigated. The effects of various factors, such as sulfuric acid concentration, liquid-to-solid ratio, CaF 2 dosage and leaching temperature were comprehensively studied.
