Continuous or fractured layer cemented by Fe (WRB 2022 Ch 3.1.27, p. 59).
Since v0.9.312 a layer qualifies when its Fe cement is recorded (an iron
pan, pan_type ferricrete or ironpan, or plinthite \>=
min_plinthite_pct) and its cementation class is at least strongly
cemented (criterion 4; until v0.9.311 moderately was enough), over
min_thickness cm of adjoining layers (criterion 7). A layer whose
Fe cement or cementation is not recorded is undecided.
