Potassium fertilizer via hydrothermal alteration of K-feldspar ore

Distribution and Origin of Clay Minerals During Hydrothermal Alteration of Ore Deposits

Routine characterization and interpretation of complex alkali feldspar intergrowths†k

Almost all alkali feldspar crystals contain a rich inventory of exsolution, twin, and domain microtextures that form subsequent to crystal growth and provide a record of the thermal history of the crystal and often of its involvement in replacement reactions, sometimes multiple. Microtextures strongly influence the subsequent behavior of feldspars at low temperatures during diagenesis and weath...

Isochron dating of sediments using luminescence of K-feldspar grains

[1] A new method for dating well-bleached sediments is presented, with results for thirteen samples from China. The method uses an isochron constructed from the measurement of natural radiation doses received by potassium-feldspar grains in a range of grain sizes using the infrared stimulated luminescence (IRSL) signal. The age of deposition of the sediment is calculated from this isochron and ...
