| description | Geological, mineralogical and chemical properties of a sepiolite occurrence, located in the south of Kıbrıscık
township of Bolu Province, northcentral Turkey, have been investigated in detail, and new mineralogical data have been
obtained. Differing from the sedimentary sepiolite deposits, mostly associated with the carbonate/evaporite sequences, Kıbrıscık
sepiolite occurs in the Köroğlu (Gallatian) Volcanic Belt, and has formed by the hydrothermal alteration of the vitric tuff unit of
Middle Miocene aged Deveören Volcanites. The mineral, which shows a similar XRD pattern to sepiolite, gives DTA and IR
patterns with close resemblance to those of palygorskite, in addition to its chemical composition with rather high alumina
content. There are indications of monoclinal symmetry, determined by XRD, and it is thought to be possible that the material
represents a new mineral phase. |
