20.500.12556/DiRROS-25107 Karst Rock Weathering of The Great Pyramid of Giza Zakrasevanje Keopsove piramide The exposed stone blocks of soft carbonate rock, from which the pyramid is built, quickly develop a distinctive form and rock relief. The outer parts of the blocks are often undercut into overhangs. On their upper parts, a protective crust forms through rock dissolution and rapid recrystallization under the influence of occasional rain and seeping water, shielding the rock from wind erosion and dissolution. This crust, in turn, is dotted by small pits, whose bare surfaces remain exposed to wind erosion, allowing them to expand and grow deeper. In the lower sections, where the rock is fully exposed, wind erosion primarily carves out larger cups and channels. A thin crust may occasionally form over these sections, but tends to flake off quickly. This process suggests rapid karstification and the ongoing disintegration of the stone blocks. Izpostavljeni skalni bloki mehke karbonatne kamnine, iz katerih je piramida, razmeroma hitro pridobijo značilno obliko in skalni relief. Na zunanjih delih so bloki največkrat previsno spodjedeni. Njihov zgornji del, ki ga občasno dosegata dež in polzeča voda, prekriva skorja, ki nastane z raztapljanjem kamnine in hitro rekristalizacijo ter skalo ščiti pred vetrom in šibkim raztapljanjem. Razčlenjen je z vdolbinicami, katerih površina je pogosto gola in zato izpostavljena vetrni eroziji, kar omogoča njihovo rast. V spodnjem delu, kjer je skala gola, v večini primerov povsem prevladujejo skalne oblike, ki jih dolbe vetrna erozija, torej večje vdolbine in žlebovi. Tanka skorja, ki občasno prekrije njihovo površino, se hitro lušči. Sklepamo na hitro zakrasevanje in razpadanje skalnih blokov. carbonate rock rock relief complexometry Great Pyramid of Giza Egypt karbonatna kamnina skalni relief kompleksometrija Keopsova piramida Egipt true false true Angleški jezik Slovenski jezik Imetniki avtorskih pravic na prispevkih so avtorji Članek v reviji 2026-01-10 09:11:46 2026-01-10 09:11:47 2026-02-15 18:34:37 0000-00-00 00:00:00 2025 0 0 str. 11-37 št. 1 letn. 54 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-08-01 551.3.053:552.54(620.21/.22) 0583-6050 10.3986/ac.v54i1.14332 246889987 https://ojs.zrc-sazu.si/carsologica/article/view/14332 0 f5236331-edfe-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37779 Knez.pdf Knez.pdf 1 0682357EAC118E94D8715F947749BA9B 9c8d80dc03d7b78401b4f31f32696e666c1ccc8788ad3a8dce56c94f14042689 09032930-edff-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37780 Znanstvenoraziskovalni center Slovenske akademije znanosti in umetnosti Acta carsologica = Krasoslovni zbornik 0 0 0
