Pudinga
rocha sedimentaria
As pudingas son un tipo de conglomerado formado por croios caracteristicamente redondeados cuxa cor adoita contrastar coa matriz de gran fino que os rodea, xeralmente areosa, e co cemento. Os croios redondeados de cor contrastada dánlle a este tipo de conglomerados a aparencia de uvas ou pudin.[1][2] Hai diferentes tipos de pudingas, con diferenzas en composición, orixe e distribución xeográfica. Exemplos de pudingas de diferentes tipos son as pudingas de Hertfordshire, Schunemunk, Roxbury e illa de St. Joseph (illa Drummond).
