Spanish term

materiales tipo raña

Spanish to English Science Geology raña
I am translating a report about Andalusian geology. The sentence is as follows:
"Se trata de materiales tip raña de colores rojos, debido a procesos de rubefacción, que se encuentran dispuestos discordantemente sobre las arenas basales. Están formados por gravas de origen fluvial, principalmente cuarcíticas y pizarrosas, junto con arenas y arcillas. En algunos puntos pueden presentarse costras ferruginosas."

I find this explanation of 'raña': Depósito de cantos de cuarcita, mezclados con arcillas o arenas, que se extiende al pie de una cordillera o en el borde de una cuenca de sedimentación.

It is a term from Spain, but I don't know if I have to translate this explanation, or just write 'raña-type materials', or is there an English term? Since the paragraph goes on to explain their composition, should I just indicate that it is a Spanish term without equivalent.

Thank you. I appreciate your advice.

"alluvial deposit" is another option.

The term raña is a local name used in the Montes de
Toledo and Extremadura to define any pebbly high
plateau. ***The rañas are old alluvial deposits with a
great surface extension forming siliciclastic conglomerate deposits with alluvial origin and little thickness.***
They crop out as hanging mesas (small plateaus)
above modern rivers, at variable height and slopes
depending on their geographical location, but in any
case with higher values than river terraces.

The soil profiles C.1 and C.2 are located respectively on
fluvial Pliocene deposits and alluvial-fan deposits (Rañas)
that are disconnected from the current Quaternary river
network.

In addition to Syria and Persia, mentioned by Huntington, there is rather deep alluvial fill in parts of Spain, Portugal and Greece. Such deposits are termed ranas in the Iberian Peninsula.

Hernandez-Pacheco (1950) described Upper Pliocene alluvium representing a phase of intense deposition that occurred during a climate of accentuated semidesert character with intense, accidental rains. Ribeiro and Feio (1950) claimed that the Mediterranean climate with its long dry season is sufficient to maintain or form ** rañas.** Mistardis (1950a, 1950b, 19500 noted similar deposits in Greece and classified pediment surfaces of the Mediterranean region in detail. There is some disagreement about age of the rañas and related alluvial features, whether Late Pliocene or Early Pleistocene, but the above authors would concur with Huntington that aggrading conditions required drought, while the dissection of detrital slopes occurred in more moist periods.

At intermediate latitudes, under subtropical to wet temperate climates (warm temperate – FAO) Acrisols tend to form readily on more easily weatherable rocks, such as schists and basic gneisses, granulites, amphibolites, gabbros, and, especially, on old, sedimentary materials with notable permeability, such as **(i) deposits of major flood events (formations that in the Iberian Peninsula are known as “rañas”**, and which are probably of Plio-Pleistocene age),
Note from asker:
Thank you. I guess I didn't look far enough in the English literature. I think it would be best to stick with the original Spanish term (saying 'materials of the type known as raña') since it is explained quite well in the following text.
