Quarry house churches
In the Hauskirchen quarry (locally also Liechtenstein quarry ) in the Lower Austrian Weinviertel, Sarmatian gastropod-bearing oolites ("snail limestone sandstones ") were extracted.
history
The traces of the former dismantling in the quarry, north-northeast of the parish church Hauskirchen on the north slope of the Galgenberg, can still be seen today in the form of cut walls and cuboids left behind with pincer holes. An inscription in the part by the road testifies to the use of this quarry in 1871 ( 18 FE 71 ).
Facies
It is an agitated, hypersaline shallow water area in which the oolites were formed. Again and again they contain layers of bivalve vein cells with a partly excellent state of preservation of the shell substance . Even specimens with a mother-of-pearl layer and original color preservation are not uncommon. In the thin section, ooids, which are partly radially formed, dominate, with quartz, potassium feldspars, small gastropods and bivalves as well as foraminifera serving as nuclei. These components are cemented by fine-grained, in places radial-fibrous, low-iron calcite.
use
The coarse to fine-grained sand-lime brick was considered easy to work with fresh from the mountain , but exposed to the air it becomes harder and harder, which makes it very resilient. The mined oolite was used, for example, in the churches in Großkrut, Fallbach, Paasdorf, Walterskirchen , Stillfried and Falkenstein Castle .
Trivia
Towards the end of the Second World War , a small distillation plant for fuel production was built in the quarry as part of the "Geilenberg program", the remains of which are still there today.
