Comment on “Spatial changes in inclusion band spacing as an indicator of temporal changes in slow slip and tremor recurrence intervals” by Nishiyama et al.

Abstract A recent paper by Nishiyama et al. (Earth, Planets, and Space 73:126) examined syntectonic quartz veins to constrain temporal variations in the recurrence intervals between slow slip tremor events. The authors claim that examining liquid-volume fraction of fluid inclusions veins, they can accurately reconstruct pore-fluid pressures (and therein) were operative during faulting at ~ 15 km depth an exhumed subduction melange. From these observations, infer large (from lithostatic hydrostatic) decreases pressure occurred faulting, drove increases supersaturation rapid precipitation over time scales consistent with repeat times seismologically observed Here, I show al.’s analysis neglects reasonable uncertainties reconstruction. When those are included, results become ambiguous as whether any variation vein formation all, negating validity many subsequent conclusions. Graphical
