The rate of charge deposition in quartz grains irradiated in natural conditions is computed by radiation transport modeling. Quartz luminescence models are modified with the addition of the resulting charge deposition term, and the influence of this process on the optically stimulated luminescence (OSL) signal is analyzed. The results indicate that the charge deposition occurring in the quartz grain during the time of residence within rock could lead to the depletion of trapped holes in the recombination centres. For the two different quartz models investigated here, complete depletion is expected to occur for rock ages between 500 Ma and 1100 Ma. It is predicted that for sedimentary quartz derived from such rocks, the OSL signal is dominated by the slow component. It was also found that the shape and saturation level of the natural sensitivity-corrected dose response curve (DRC) of quartz is affected by the charge deposition; specifically, a linear reduction of the saturation level with the age of the rock is observed.

通过辐射传输模型计算在自然条件下照射的石英颗粒中的电荷沉积速率。石英发光模型通过添加最终的电荷沉积项进行修改，并分析了此过程对光激发发光（OSL）信号的影响。结果表明，在岩石中停留期间，石英颗粒中发生的电荷沉积可能会导致复合中心陷留的空穴耗尽。对于这里研究的两种不同的石英模型，岩石年龄在500 Ma至1100 Ma之间预计会发生完全耗尽。可以预料，对于源自此类岩石的沉积石英，OSL信号主要由慢分量主导。还发现，石英的自然灵敏度校正剂量响应曲线（DRC）的形状和饱和度受电荷沉积的影响。具体而言，观察到饱和度随岩石年龄的线性降低。
