Abstract
The wad-minerals from limestone caves of Yugoslavia, China and Japan were studied. X-ray diffraction analysis revealed five minerals; birnessite, 10A-manganite, pyrolusite, todorokite and goethite. The heavy metal elements, Mn, Zn, Fe and Cr have been detected by X-ray fluorescence analysis and their contents were roughly determined. The condensation water introduced directly from the covering soils formed by the continental weathering and the deriving corrosive water interaction with limestone could be the input sources of manganese and other metal elements into the system.
