Welcome

Discover completely new world!

In front of you, the page that will show you the extremely valuable treasure of our planet, interesting, intriguing and delightful with its beauty. We want to show you the beauty of the rock, which seemingly may seem boring and uninteresting, we will prove that the rock, seemingly indestructible and unchanging, can change, transform and evolve over time. We present you hydration caves, unusual morphological forms, formed as a result of chemical changes that take place in the rock. On this site you will not find boring scientific rules, just a simple and pleasant description. Of course, for those interested, we will include references to geological literature, sources of citations and data sets.

Hydration caves are the morphological effect of chemical weathering on the surface of the quarries in Dingwall and several other places in the world. Research conducted in connection with the transition of anhydrite to gypsum on the surface of the quarry floor focuses on many aspects of this process. First of all, it is important to carry out general geological research aimed at lithological profiles, geological cross-sections, running and dipping measurements and rock sampling. Also, an inseparable element of this type of work is to see what the gypsum rock hides inside anhydrite and carrying out petrographic tests. Moreover, as we already know, the effect of anhydrite hydration is the formation of hydration caves and numerous forms of land relief rarely found in the world. Hence, morphology and its analysis using several methods, including photogrammetry, is also important. The morphology of the studied area is related to tectonic issues, because hydration causing an increase in the volume of the rock medium causes stresses and, at the same time, numerous deformations.

 

The results of the above-mentioned works are included on our website in the form of multiple pages and subpages of a complex text. The description, documentation and morphological, petrological and structural analysis of the weathering zone of gypsum-anhydrite rocks in Dingwall are included here.

In addition, we have included documentation data related to the site in the Harz Mountains and the closed Ukrainian quarry in Pisky.

 

The maintenance of this website and the presented results of research in Dingwall were financed from the funds of the project entitled “Hydration Caves from the wethering zone in Dingwall, Canada – three-dimensional documentation, characteristics and genesis” as part of the competition named “Diamond Grant ” financed by the Ministry of Science and Higher Education in Poland.

Here you may also discover another wonder of the gypsum weathering zone – gypsum tumuli. Gypsum tumuli are morphological forms known from many places on earth, formed as small domed landforms of relief, with a diameter of several decimeters to several meters and a height exceeding 1 m, formed by detachment of the surface layer of weathering gypsum rocks under semi-arid climate or microclimate conditions.

Hydration faves and forms

More than 60 years have passed since the quarry ended works in 1955 at the bottom of the disused quarry in Dingwall. From the moment when, as a result of mining works, the layer of gypsum was removed from a thickness of several meters, the exposed anhydrite is subjected to even greater influence of meteoric waters. The ongoing gipsyfication leads to an increase in the volume and swelling of the rock. The direct effect of the swelling is the formation of domes, wigwams, ridges, inside which a rock void of various sizes and varying degrees of access is created. These voids at the moment of human accessibility were called hydration caves, and the rock surrounding the voids is called the morphological hydration form.

Below are the most important aspects related to the above-mentioned geological and morphological objects. Just click to find out what genesis is behind their formation, whether the location of the caves in the quarry is dense and check whether perhaps the dimensions of the hydration caves are sufficient for us to go inside and feel comfortable.

Study areas

In Canada, in the northern part of the Nova Scotia province, we can find many gypsum outcrops of the Carboniferous age. One of them is a closed gypsum quarry at Dingwall, whose activity has been closed since 1955. The general profile of this place presents 8 m of gypsum and 10 m of anhydrite. Anhydrite as chemically unstable mineral is subjected to atmospheric factors, including rain and snow, which results in chemical transformation and the formation of secondary gypsum.

Site at Dingwall

Site at Pisky

The tiny village of Piski in western Ukraine, in the Lviv region, is located within the outcrop of the Badenian gypsum. For this reason, in the previous century, a gypsum quarry was created, which has now practically lost its importance. Similarly as at Dingwall, during exploration of gypsum layers, anhydrite was discovered which turns into gypsum under the influence of water activity.

Another place with weathered anhydrite can be found in the central part of Germany between the towns of Walkenried and Bad Sachsa, towns in Lower Saxony. That’s where the gypsum-anhydrite plateau is visible, and impressive in terms of its panorama and scenery. This plateau was created in a natural way and is covered with forest.
