Lanthanide element signatures are key to understanding many astrophysicalobservables, from merger kilonova light curves to stellar and solar abundances.To learn about the lanthanide element synthesis that enriched our solar system,we apply the statistical method of Markov Chain Monte Carlo to examine thenuclear masses capable of forming the $r$-process rare-earth abundance peak. Wedescribe the physical constraints we implement with this statistical approachand demonstrate the use of the parallel chains method to explore themultidimensional parameter space. We apply our procedure to three moderatelyneutron-rich astrophysical outflows with distinct types of $r$-processdynamics. We show that the mass solutions found are dependent on outflowconditions and are related to the $r$-process path. We describe in detail themechanism behind peak formation in each case. We then compare our masspredictions for neutron-rich neodymium and samarium isotopes to the latestexperimental data from the CPT at CARIBU. We find our mass predictions givenoutflows that undergo an extended (n,$\gamma$)$\rightleftarrows$($\gamma$,n)equilibrium to be those most compatible with both observational solarabundances and neutron-rich mass measurements.
