Diagnostic horizons depths

For the Brunisolic order, is the depth of the diagnostic Bm horizon greater than 5cm? And for Gleysol, a Bg greater than 10cm?

(For these two the depths are only given for the other potential diagnostic horizons but not for the main diagnostic horizon)

Thanks!

For the Brunisolic soil order the diagnostic horizons are a Bm, Bfj or Btj > 5 cm thick or Bf < 10 cm thick. Consider that Brunisols have undergone only slight development from parent material.

For Gleysol, the diagnostic horizon is a Bg (or Cg > 10 cm thick within 50 cm of the soil surface). Consider the conditions which lead to a gleyed horizon (e.g. Bg).
