The Almopia Speleopark caves are located at the Almopia basin in northern Greece, at the foothill of Voras Mountain, and are formed in the Maestrichtian limestones of the Pelagonian zone. They are studied on the basis of their meso- and micro-scale morphology as well as their horizontal pattern, in order to investigate the character of the forming aquifer. Emphasis is given on the morphological description of the Loutra Almopias Cave. Cave morphology is dominated by the presence of cupolas, rock bridges, ridges and “windows”, abrupt terminations of fracture guided passages, pendants, rising channels, pseudonotches, false-floors and spongework. Speleogens indicate a speleogenesis due to slowly natural convecting hot water bodies. Phreatic calcite from the Varathron Cave is analyzed on the basis of the fluid inclusions in order to investigate the physicochemical conditions of the convecting water bodies. This has shown that the calcite was formed at temperatures ranging between 120 and 189 ºC, with a peak around 150 ºC. The fluids were dominated by NaCl of very low salinities (0.2-1.0 wt% NaCl equiv.), showing probably the incorporation of meteoric waters. ; Speleopark Almopia je ob vznožju gore Voras v porečju Almopije v Severni Grčiji. Jame so nastale v maastrichtskih apnencih Pelagonske cone. Z analizo jamskih skalnih oblik in tlorisov jam smo raziskovali pogoje njihovega nastanka. Največ raziskav smo naredili v jami Loutra Almopias. Med oblikami so značilne kupole, skalni mostovi, skalni grebeni, okna, nezvezni zaključki rovov nastalih ob razpokah, dvigajoči se kanali, lažne korozijske zajede in tla ter prepleti drobnih kanalov. Iz skalnih oblik sklepamo, da so jame nastale s korozijo počasnih konvekcijskih tokov termalne vode. Fizikalno-kemične pogoje speleogeneze smo določali z analizo tekočinskih vključkov v freatičnem kalcitu iz jame Varathron. Temperatura izločanja kalcita je bila med 120°C in 180°C, z vrhom temperaturne porazdelitve pri 150°C. Nizka slanost tekočinskih vključkov, masni delež soli je med ... |
