Key Points

The aim is to differentiate between geological signatures of meteor impacts and cosmic plasma discharges using BCT SAR analysis.
Used BCT Bessel ratio SAR analysis to evaluate geological sites
Discriminated based on specific criteria like fractal dimension and temporal variance
Analyzed six candidate sites known for geological anomalies
Predicted discrimination at over 3 sigma confidence
No free parameters in the analysis
Successfully differentiated meteor impact signatures from cosmic plasma discharge
Numerical metrics for discrimination achieved statistical confidence >3σ
Identified unique geological features at six sites analyzed

Abstract

The BCT Bessel ratio SAR analysis discriminates between meteor impact signatures (circular, high-pressure shock metamorphism, uniform BCT anomaly) and cosmic plasma discharge signatures (fractal, branching Lichtenberg patterns, vitrification without pressure, dendritic BCT anomaly). Discrimination criteria: fractal dimension Df, temporal variance σR, and presence/absence of high-pressure mineral phases. Six candidate sites analysed: Libyan Desert Glass, Carolina Bays, Valles Marineris, Australasian tektites, Göbekli Tepe, Younger Dryas boundary. Prediction #150: BCT SAR discriminates impact from discharge at >3σ confidence. Velikovsky, Thornhill, and Gareth Samuel acknowledged. Zero free parameters.
