Carbonate in soil: a theoretical consideration on, and proposal for its fabric analysis. 2. Crystal tubes, intercalary crystals, K fabric.

Abstract

The spatial arrangement (fabric) of carbonate in 7 different soils was studied to make a proposal for its fabric analysis. These soils, which have been developed in calcareous loess and marine deposits, are located in Afghanistan, the USSR, Germany and the Netherlands.In the first part of this study (Bal, 1975) the simple plasmic fabrics crystic, calcic and fibrous have been defined. Their distinction is primarly based on theoretical considerations of Brewer's concepts (Brewer, 1964).In this second part the morphology and genesis of carbonate crystal tubes and intercalary carbonate crystals is dealt with.Also K-fabric, the carbonate fabric introduced by Gile et al. (1965) is discussed and redefined. The fabrics crystic, calcic and fibrous are simple fabrics; the K-fabric, on the contrary, is principally a compound fabric. This means that K fabric is composed of one or more of these simple fabrics. (Abstract retrieved from CAB Abstracts by CABI’s permission)
