Mineralogy and geochemistry of soils/paleosols formed in contrasting pedoenvironments (oxidizing vs. reducing) on pure cretaceous limestones in Istria, Croatia
The Istrian peninsula represents the NW part of the Adriatic Carbonate Platform. It is composed of a succession of carbonate deposits more than 2000 m thick (of Middle Jurassic to Eocene age), and is overlain by Palaeogene (Eocene) Foraminiferal limestones, Transitional beds (Globigerina marls) and flysch deposits (Fig. 1). Carbonate deposits of the Istrian Peninsula are mainly covered with terra rossa, a polygenetic relict soil, formed during the Tertiary and/or hot and humid periods of the Quaternary and with Quaternary pedo-sedimentary complexes. Carbonate rocks also exhibit numerous exposure surfaces reflecting emergence. Some subaerial exposure surfaces are associated with Jurassic, Cretaceous and Lower Palaeogene bauxites and/or palaeosols. Therefore, the Istrian Peninsula represents an excellent area where soils/paleosols developed on carbonate rocks can be studied. Especially interesting are red and greenish-grey clay rich and carbonate free soils and paleosols situated on limestones of Cretaceous age containing very low content of insoluble residue (less than 1 wt.%).
