A noniterative solution of the (U‐Th)/He age equation

We present a direct solution of the (U‐Th)/He age equation for age that obviates the need for an iterative solution. The uncertainties of this solution are sufficiently small to allow its use as a quasi‐analytical solution of this age equation. The direct algorithm has the obvious advantage of greater simplicity. Moreover inversion algorithms for (U‐Th)/He age profiles and coupled three‐dimensional thermal‐age‐landscape models will profit from the resulting gain in computational speed.
