Multi-method study of the Roman quarry at Podpeč sedimentary succession and stone products

The paper presents a multi-method characterisation of the Roman quarry middle Lower Jurassic (Pliensbachian) limestone situated in village Podpeč, south Ljubljana, and examples placement stone products made from micritic, fine-grained, oolithic facies into known extent quarry. 23 m rock succession ancient was exposed at northern tip St. Ana Hill by archaeological trenching. Petrological, micropaleontological, mineralogical, geochemical, isotopic analyses carbon, oxygen, strontium were performed order to characterise rocks exploited Additionally, new detailed geological map wider Podpeč area prepared, which defines detail lithostratigraphic units area. recorded contains that also occur modern part Interpretation sedimentation environment is consistent with previous interpretations occurred an internally differentiated lagoon. studied characterised δ13C isotope values ranging -2.44 +2.5 ‰; δ18O -4.0 -1.2 87Sr/86Sr 0.707414 ‰ (SD 0.000003) 0.707329 0.000012). Sr can prove decisive factor when studying provenance products, while help narrow place extraction within Podpeč. high positive correlation SiO2 Al2O3, K2O TiO2 recognised both logged indicates low terrigenous input depositional further confirms determination. By applying approach quarry, we have reliably determined their origin successfully applied this several fine-grained limestones.
