Generally, soils which have 20% organic matter or more organic material to a depth of 35cm is considered as "organic soil" and taxonomically referred to as histosol [3].
Las unidades Gleysol Haplico (GLha), Molico (GLmo) e Histico (GLhi), Vertisol Gleyico (VRgl) e Histosol Hemico (HShm), tienen horizontes Ag y Cg de colores gris y gris oscuro (5 Y 6/1, 5 Y 4/1) (Tabla II), que indican gleyzacion y drenaje interno muy pobre desde la superficie, al situarse en llanuras de inundacion y cubetas de decantacion.
The significance of a thin coal within the open water facies association depends on its origin: given its discontinuous nature and lack of underlying roots, it likely represents organic material (vitrain) resulting from coalification of a transported lycopsid log rather than an in-situ histosol (peat).
