Abstract
The two studied ornamental stones, `Siklós-green´ and `Siklós-rose´
are quarried in the
Villány Mountains in South Hungary. The former one belongs to the Middle
\hboxTriassic Zuhánya Limestone Formation while the latter one is a
part of the Upper
Jurassic Szársomlyó Limestone Formation. Besides pinkish, yellow and
white varieties of `Siklós-rose´ also exist.
Zuhánya Limestone was formed in an outer ramp setting representing the
deepest facies.
Szársomlyó Limestone contains pelagic fauna, microoncoids and peloids.
The
microoncoids were accumulated in a relatively shallow part of a drowned
platform and were redeposited.
The petrophysical tests showed that uniaxial compressive strength of both
limestones was
in the order of 80 MPa. It is easy to polish them and their polished
surfaces are
decorative. Both stones are used as inner wall or floor cover but due to
its frost resistance
`Siklós-rose´ is also applicable for outer surfaces. The byproduct of
ornamental stone quarries are appropriate for aggregates.
Better petrophysical properties of `Siklós-rose´ are attributed to the
more homogeneous texture of the Jurassic limestone
