Abstract
Geophysical studies were conducted on the ancient quarry of the Bronze Age “Novonikolaevsky” in theTrans-Urals, Russia. The purpose of these studies was to investigate the possibility of determining the relief of bedrock rocks buried under a thick layer of sedimentary rocks and processed soils according to GPR data, to build a model of an ancient quarry using these data, as well as to estimate the amount of ore and copper mined. The survey was conducted by SIR-3000 with a 400 MHz antenna in 16 parallel profiles. A description of the method of survey and interpretation of the results was given. A ditch was dug in the quarry and geological sections along the western and eastern walls were made. The obtained GPR sections were compared with geological data. The results of the excavation at the quarry correspond well to the boundaries of the reflections of electromagnetic waves from the bottom of the ancient quarry. A three-dimensional model of the quarry was built during its operation. Based on the model obtained, an estimate was made of the amount of ore mined. The results allowed establishing that in the Bronze Age, 2.5 tons rough copper could be smelted from mined ore.
