Study On The Diagenetic Calcareous Accumulations In A Soil Profile From Floresti (Cluj County, Romania), Horea Bedelean
Study On The Diagenetic Calcareous Accumulations In A Soil Profile From Floresti (Cluj County, Romania), Horea Bedelean
Studia UBB Geologia
The studied calcretes developed in two different levels (horizons) in the soil profile from Floreşti (Cluj County). The deposits outcropping in the area are represented by Bartonian-Priabonian sedimentary rocks (Ciuleni Member, Viştea Limestone) and the Quaternary horizon (terrace of Someşul Mic River, consisting of pebbles of different origin), which represent the parent rock of the soil. A detailed petrographical and mineralogical description of the calcretes is given below, based on macroscopic, microscopic and X-ray diffraction analysis. It led to the conclusion that the calcretes from the studied profile have a pedogenic origin. The calcretes consist of distinctive subhorizons within the …
Considerations On The Parent Material In The Soil Developed On The Evaporite Deposits From Stana (Cluj District), Horea Bedelean
Considerations On The Parent Material In The Soil Developed On The Evaporite Deposits From Stana (Cluj District), Horea Bedelean
Studia UBB Geologia
This research concerned three profiles developed on Eocene (Priabonian) gypsum parent material from Stana (Cluj district) in order to investigate their properties. The soil and parent material samples were collected from individual horizons in each profile. Both the mineralogical and structural-textural features of the parent material (evaporitic deposits) reflect the depositional context. From a mineralogical point of view, the deposits are represented by gypsum, and anhydrite. Typical sulfate facies are present: laminitic, nodular, gypscretic, and entherolitic. Physical and mineralogical properties of the soil layers were determined in the laboratory. The field observations and the results of the analyses allowed us …
