Thermoluminescence of Quartz and Feldspar Sand

Thermoluminescence of Quartz and Feldspar Sand

+

Quartz and feldspar grains exhibit laboratorystimulated thermoluminescence (TL) as a consequence of their natural radiation exposure while buried in a sedimentary environment. The sources of this natural radiation are primarily 40K, 238U and 232Th and their daughter products, and cosmic ray muons. The magnitude of the TL emission in a grain is dependent upon the size of the past radiation ...

Feldspars are a group of rockforming aluminium tectosilie minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodiumcalcium) feldspars and the alkali (potassiumsodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.
