ha ha. yeah. wow, yours were clean. yeah. joe? you re going to me for the last block, aren t yo. no, the person who goes first the first time is last the last time. haven t you figured that out? this story hit home for weeks because i m on the cusp and made me realize i should eat more pasta because some criminal nation is good if it gets it out of going on lame rides with your cousins. you really hate your does sniens i do. no, i m just teasing. they re adorable. all right. coming up awoke petition to tweak a definition. m eds. and it s unlikely to improve without treatment. i felt like my movements were in the spotlight.
Potassium (K)-rich feldspars are one of two mineral types typically used for optical dating. Feldspar grains can contain up to ~14 wt% K that gives rise to an internal dose rate component. This internal component can comprise a significant proportion of the total environmental dose rate to which a mineral grain is exposed. The environmental dose rate term the denominator in the optical age equation determines the rate at which electronic charge is transferred into the crystal lattice of a mineral grain over its period of burial. Not all feldspar grains have the same K concentration, so internal dose rates differ between individual grains. K concentrations can range from 0 to 14 wt% due to the variable compositions of feldspar phases, differing proportions of discrete feldspar phases and/or the presence of other mineral inclusions in grains. Numerous techniques are available for determining the K concentrations of individual grains, but are time-consuming, and either lack the spatial re
