1. Introduction

As part of the interdisciplinary expedition SPECTRA-XI, new methods for detecting and analyzing microscopically fragmented relics were applied. At its core was a combination of Spectral Shift Fragment Gathering (SVG) and depth-adaptive X-ray imaging. The goal: non-extractive recovery of spectrally encoded microparticles from stratigraphic contexts without destroying the surrounding sediment layers.

2. Methodology

2.1 Spectral Shift Fragment Gathering (SVG)

This technique is based on the hypothesis that certain ancient materials – particularly organo-mineral composites – exhibit slight spectral shifts when exposed to photons if their molecular bond has changed due to aging or embedding.

• Device: Vector Coherence Scanner VCS-9β
• Wavelength Range: 220–950 nm (UV-NIR)
• Sampling Interval: 12 µm laterally, 3 µm vertically
• Shift Detection: up to Δλ ≈ 0.013 nm

By sequentially rastering, so-called "spectral trails" could be mapped, which indicate fragmentation zones or previous thermal events (e.g., fire pits, smelting).

2.2 X-ray Imaging (XR-Imaging)

The complementary X-ray analysis was performed in situ with a portable high-resolution device (Korpix-Scan 4X). Both:

• Classical transmission images
• Phase contrast images
• Multi-layer raster X-rays (MLRR)

were used, allowing even laminated artifact layers (e.g., painted ceramic fragments, charred papyrus layers) to be resolved.

3. Results

3.1 Site A – Subterranean Cult Courtyard (Coordinates 48.82°N, 9.11°E)

• SVG identified a cluster zone of 38 fragment objects with Δλ between 0.021–0.034 nm in the UV range – typical for oxidized amber bonds.
• XR-Phase contrast revealed microscopic incrustations on a charred artifact: including a possible totem fragment carrier with symbolic indentations.

3.2 Site B – Stratigraphic Shaft (Layer 5b)

• Spectral data indicated inorganic splinters from multi-layered metal shimmer, the shift of which suggests possible cosmogenic influence (e.g., meteorite impact).
• X-ray images revealed ring-shaped melting patterns that only occur with extremely localized high-energy impact – possibly due to ancient energization (subject of future studies).

4. Interpretation

The combination of SVG and X-ray methods enables a completely new type of object reconstruction, in which not only the material substance but also its energetic history can be reconstructed.

It is particularly worth noting that spectral shift analysis could reveal indications of previous transport states and exposure levels of objects – an indication of lost trade routes, ritual relocations or thermally induced fragmentations.

5. Outlook

The procedure of Spectral Shift Fragment Gathering opens up new perspectives for:

• Paleo-Photonics
• Non-invasive cultural heritage rescue
• Precise dating through molecular shift

Future missions will combine the method with hyperspectral aerial mapping and penetrate deeper into subsurface zones (<12 m). Coupling with quantum resonance tomography is also planned.
