## In short

A buried compositional layer nested within the crust mediates the causal link between interior cooling and the surface fault geometry actually observed.

## What they found (results)

Critical-taper analysis of Mercury's lobate scarps found fold-and-thrust-belt geometry consistent with weak, low-angle faults lubricated by a heterogeneously distributed graphite-bearing crustal layer, implying greater cumulative radial contraction than previously estimated.

These researchers were not testing DSRP. The finding is theirs; the correspondence to DSRP is drawn by this site.
