Can we use t suffix as Bt horizon in a horizons that we did not observe any micro-lamination clay coating in thin section of the soils.
we had doubt for clay coating in field observation.
what is your idea about hypocoating of clay+OM and Fe/Mn oxides.
Can we use t suffix in soil description Table?
P1: In calcareous shale parent material, Udic, We Observed hypocoating of clay+OM and Fe/Mn oxides in thin section but we did not micro-lamination clay coating

A 0-17 35 6.98 1.6
B(t or w)1 17-33 32.5 7.14 4.26

Whats your idea about fragmented micro-lamination clay coating (paplue)? can I use t suffix in this soil profile?
P2:In a shale parent material, Udic, We observed fragmented micro-lamination clay coating (paplue)
