Večmetodne raziskave sedimentarnega zaporedja in kamnitih izdelkov rimskodobnega kamnoloma v Podpeči

The paper presents a multi-method characterisation of the Roman quarry of the middle Lower Jurassic (Pliensbachian) limestone situated in the village of Podpeč, south of Ljubljana, and examples of the placement of stone products made from micritic, fine-grained, and oolithic facies into the known extent of the quarry. 23 m of the rock succession from the ancient quarry was exposed at the northern tip of the St. Ana Hill by archaeological trenching. Petrological, micropaleontological, mineralogical, geochemical, and isotopic analyses of carbon, oxygen, and strontium were performed in order to characterise the rocks exploited in the quarry. Additionally, a new detailed geological map of the wider Podpeč area was prepared, which defines in detail the lithostratigraphic units in the area.Članek predstavlja večmetodno karakterizacijo rimskega kamnoloma v vasi Podpeč južno od Ljubljane in primere umeščanja apnenca kamnitih izdelkov iz spodnjejurskih (pliensbachijskih) mikritnih, drobnozrnatih in oolitnih faciesov v znan obseg kamnoloma. Na severnem robu hriba sv. Ane je bilo z arheološkimi izkopi razkrito 23 m debelo kamninsko zaporedje antičnega kamnoloma. Za karakterizacijo kamnin, ki so jih izkoriščali v kamnolomu, so bile opravljene petrološke, mineraloške, mikropaleontološke in geokemične analize ter izotopske analize ogljika, kisika in stroncija. Poleg tega je bila izdelana nova podrobna geološka karta širšega območja Podpeči, na kateri so natančno opredeljene litostratigrafske enote na tem območju
