The literature dealing with secondary carbonates in loess-paleosoil sequences is in
many cases ambiguous, which means that different concepts are used for the same features,
whereas certain concepts referring to different types are used as collective nouns.
The aim of this study is to give a review on this nomenclature and to draw comparision
between the various types and concepts. As a main guiding principle the article of
Becze-Deák et al. (1997) is used, because it has formulated a proposition of a nomenclature
which would be worthwhile to adopt. The terms and concepts introduced by their work
are exact, referring to certain separated secondary carbonates and are of decisive
importance with a view to paleoenvironmental reconstruction.
The research of secondary carbonates in loess-paleosoil sequences is of great importance,
through providing detailed information on the paleoenvironment, especially on the
former moisture conditions (including leaching processes). Secondary carbonates originate
from the vertical, horizontal or in situ resettlement of carbonates during pedogenesis
in the soil-sedimentary environment. Among others, calcified root cells, hypocoatings
and needle-fiber calcite are classified into the microscale category, while concretions
(e.g. loess dolls) belong to the macroscale types.
