Donbasite and alushtite discovered by E.K. Lazarenko
(1942) and P.A. Dvoychenko (1914) respectively have been named as sudoite and tosudite
later. It is proposed to regard dioctahedral chlorites as the members of
isopolymorphic rows cookeite–dickite and sudoite–serpentine. It is advisable to
use the term “donbasite” for the first row and the term “sudoite” for the
second one. Donbasite and alushtite are crystallised under conditions of higher
activity of Al, Na, Li and pH>7. These phases are alternative to dickite.
Regional spreading of donbasite and alushtite are connected with hydrothermal
alteration of Palaeozoic argillites of Donbas and Crimea.

According to the results of goniometric investigations four habitus types
of quartz crystals of “Marmarosh diamonds”-type were distinguished, namely:
hexagonal-dypyramidal, pseudo-cubic, hexagonal-prismatic and trigonal-dypyramidal.
When a fall in temperature of crystallisation medium is observed, crystal
habitus changes from hexagonal-dypyramidal into trigonal-dypyramidal. A conclusion
was made about the connection between crystallomorphological features of “Marmarosh

The
Upper Badenian evaporitic deposits from the Polish part of the Carpathian
Foredeep (Bochnia-Wieliczka area) contain units (several up to 70 m thick)
of mixed salt-clay (15–85 % of clay) sediments (zubers), originated in deep
marine (as chemical precipitates) to basin slope (redeposites) environs. Petrological
and geochemical (XRF, TA, SEM) analyses indicated varied mineral composition
of these rocks: evaporitic minerals (halite, sulphates: gypsum, anhydrite,
rare celestine) are surrounded by detritical (quartz, feldspars, muscovite,
biotite, glauconite, zircon, organic fragments) and pelitic (illite, smectite
and rare chlorite) components. Frequently occur dolomite and calcite microlithes

platform caused by formation of the Carpathians. Evaporite basin had a
continental-marine origin, water of sulphate-sodic chemical subtype and total
