A thermal spike model is proposed for the analysis of latent track formation in insulators. The model predicts that above a threshold electronic stopping power [ital S][sub [ital e][ital t]] [ital R][sub [ital e]][sup 2][similar to]ln[ital S][sub [ital e]] for 1[le][ital S][sub [ital e]]/[ital S][sub [ital e][ital t]][le]2.7 followed by [ital R][sub [ital e]][sup 2][similar to][ital S][sub [ital e]] for 2.7[le][ital S][sub [ital e]]/[ital S][sub [ital e][ital t]] ([ital R][sub [ital e]] being the effective track radius). A simple expression is derived for the evaluation of [ital S][sub [ital e][ital t]] from material parameters. A good agreement is found with literature data on latent tracks in magnetic insulators. The analysis showed that the width of the temperature distribution is [ital a](0)=(4.5[plus minus]0.25) nm and the energy deposited in the spike is 0.17[ital S][sub [ital e]].
