“…Currently, abandoned underground mines are used for various purposes, such as touristic (Klomínský et al, 2014;Sánchez, 2015;Schejbal, 2011), educational (AlRayyan et al, 2017), medical (Glass, 2000, experimental (Kaláb et al, 2012), storage (Athresh et al, 2017;Dieudonné et al, 2015) or energetic (Bailey et al, 2016;Farr et al, 2016). Nevertheless, in the field of geomorphology, the knowledge of abandoned underground mines remains quite poor, especially compared with natural caves or underground cemeteries.…”

Abandoned underground mines remain insufficiently investigated landforms, which leads to underestimating their importance within world landscapes. Even though they stand as distinct and widespread geomorphic forms, research devoted to them is underpublished in comparison with natural caves. Because many mines with disturbed entrances remain hidden, various methods of their detection are reviewed, which are essential to prevent loss of life and damage due to their eventual collapse. The most prominent manifestations of the presence of abandoned underground mines are dynamic deformations along with slower subsidence. Even small related movements of the rock mass are detectable. Interest in monitoring and modelling the motions of such processes is growing. In response to the increasing number of documented mines worldwide, their reclamation, remediation or rehabilitation are being initiated as part of efforts to restore land devastated by mining activities; complex reclamation problems can be addressed by multidisciplinary expert teams. However, it is important to note that abandoned underground mines and their particular geomorphic forms are considered to be a source of great geodiversity and hence also biodiversity. The various possibilities of future research connected with abandoned underground mines as geomorphic forms are outlined.

“…Jedná se o S-typový granit. Z akcesorických minerálů často obsahuje stejně jako I-typové granity magnetit, monazit -(Ce) a zirkon, navíc pak granát (spessartin-almandin) a andalusit (Klomínský et al 2007(Klomínský et al , 2009Fediuková et al 2008). Převážně je tanvaldský typ středně a stejnoměrně zrnitý, v zóně při kontaktu s libereckým granitem je však hruběji zrnitý a nevýrazně porfyrický.…”

“…%). Patrná je také geochemická variabilita v rámci tělesa, kdy směrem ke kontaktu s krystalinikem klesá obsah CaO, MgO, K 2 O a stoupá obsah mobilních stopových prvků (zejména F a Rb; Klomínský et al 2007).…”

“…Jeho anomální minerální složení nasvědčuje vyššímu stupni frakcionace taveniny, přestože je toto těleso lokalizováno jen několik metrů od méně frakcionovaného pegmatitového tělesa z lokality Nová Ves n. Nisou I a tedy i blízko hranice tanvaldského a libereckého granitu. Odlišným pegmatitem je i těleso z lokality Lučany n. Nisou uzavřené v libereckém granitu, které se jeví být složením silikátových minerálů nejjednodušší a nejméně frakcionované, což je ale opět v souhlase s geochemicky primitivnějším charakterem hostitelského granitu (Klomínský et al 2007;Jarchovský et al 2010). V případě turmalínu z pegmatitu z Jablonce nad Nisou (vzorek JA-4), v němž klesá poměr Fe/(Fe + Mg) směrem od centra k okraji krystalu, lze uvažovat o přínosu Mg z vnějšího zdroje.…”

We have studied silicate minerals in pegmatite nests from the Tanvald Granite (4 sites) and the Liberec Granite (1 site) in the vicinity of Jablonec n. Nisou, situated within the Variscan Krkonoše-Jizera Pluton. They contain major quartz, K-feldspar and plagioclase (An0-11), subordinate biotite, muscovite and locally schorl. Accessory phases include garnet (spessartine-almandine), andalusite, Hf-rich zircon and thorite. In addition, zinnwaldite was found in a single sample. The studied pegmatites show simple internal structure including aplitic, granitic and coarse-grained “blocky” units; the central zone commonly contains miarolitic cavity which is sometimes filled by tourmaline. The mineral composition and fractionation degree largely reflect those of the host granite; the more fractionated are pegmatites hosted by the Tanvald Granite. The pegmatite nest from Nová Ves nad Nisou II exhibits distinct mineral assemblage with zinnwaldite, pure albite and lack of biotite and garnet, therefore we suggest here a substantial modification of mineral assemblage by superimposed processes. Moreover, tourmaline (schorl) composition with local increasing of Mg toward rim indicates a possible contamination derived from adjacent rocks during tourmaline crystallization.
