Interferometric Synthetic Aperture Radar (InSAR) mapping in Vlaykov Vruh and Tsar Assen Cu-porphyry deposits, Panagyurishte ore region, Bulgaria
Bibliographic record
Abstract
Interferometric Synthetic Aperture Radar (InSAR) has been applied using SAR images from the European Space Agency (ESA) Sentinel-1 constellation, in descending orbit, to obtain the terrain displacement by means of the Coherent Pixel Technique (CPT). This Persistent Scatter Interferometry (PSI) technique was developed in 2002 by the Remote Sensing Laboratory (RSLab) of the Universitat Politècnica de Catalunya, UPC (Lanari et al., 2004; Mora et al. 2002), and recently updated by the Dares Technology team.ESA Sentinel-1 satellite constellation images were used with Single Look Complex (SLC) images and Interferometric Wide Swath (IW) acquisition mode to detect terrain displacements at Vlaykov Vruh and Tsar Assen porphyry-copper deposits (PCD) in the southern part of Panagyurishte ore district in Bulgaria.The detected displacement magnitude in Vlaykov Vruh was from 500 to 4,000 m2 while for Tsar Assen PCD it ranges from 500 to 2,500 m2 where several spots of displacement were detected.We conclude that in the waste pile area east of the Vlaykov Vruh slope instabilities occurred with a displacement of 3.5 cm. Due to a landslide along the fault structure, a slope displacement of about 4.0 cm for Tsar Assen PCD was detected.The study is supported by the Horizon 2020 co-funded GOLDENEYE project, which has received funds through Grant Agreement 869398.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
