Lithology and environment
Primary lithology: | diatomaceous siltstone |
Includes fossils? | Y |
Lithology description: La litología esta dada predominantemente por areniscas tobáceas, limolitas, limolitas diatomáceas amarillentas a blanco grisáceas. En la base del afloramiento se observa un nivel de conglomerado de forma lenticular, areniscas tobáceas con nódulos areniscosos de 0,5 a 2 cm de diámetro; la estratificación es paralela, sesgada, en general lo podemos dividir (de base a techo) en una secuencia granocreciente positiva y otra granodecreciente negativa, dentro de las cuales tenemos superficies de meteorización de coloración rojiza, compacta «hard-ground». | |
