¿Suelos del páramo de colores? Esto se da en los páramos en zonas de volcanismo activo. Son suelos antiguos, o ‘paleosuelos’. Miren como se forman.

[WRB 2022 Soil Classification System @WRB2022]

A drained peat soil with andic and vitric properties that has lost half of the topsoil (45 cm) since installing drains at 90 cm. Gleyic properties and reducing conditions at 40 cm. Therefore this soil is classified as an Andic Gleysol. See full classifications in a comment below.
