1. Introduction

As part of the interdisciplinary expedition SPECTRA-XI, new methods were applied for the detection and analysis of microscopically fragmented relics. Central to this was the 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 sedimentary 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 upon photonic exposure if their molecular bonding has been altered due to aging or embedding.

• Device: Vector Coherence Scanner VCS-9β

• Wavelength range: 220–950 nm (UV-NIR)

• Scanning interval: 12 μm lateral, 3 μm vertical

• Displacement detection: up to Δλ α 0.013 nm

Sequential scanning allowed the mapping of so-called "spectral trails" that indicate fragmentation zones or previous thermal events (e.g., burn pits, smelting).

2.2 X-ray imaging (XR imaging)

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

• Classical radiographs

• Phase-contrast images

• Multilayer scanning X-ray (MLRR)

were used, which also made it possible to resolve laminated artifact layers (e.g., painted ceramic fragments, charred papyrus layers).

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 of oxidized amber bonds.

• XR phase contrast revealed microscopic incrustations on a charred artifact, including a possible totem fragment carrier with symbolic incisions.

3.2 Site B— Stratigraphic shaft (layer 5b)

• Spectral data indicated inorganic fragments of multilayered metallic mica, the displacement of which suggests possible cosmogenic impact (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 (a 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 noteworthy that spectral shift analysis has provided clues to the objects' earlier transport states and degrees of exposure—indicating lost trade routes, ritual relocations, or thermally induced fragmentation.

5. Outlook

The Spectral Shift Fragment Gathering method opens up new perspectives for:

• Paleophotonics

• Non-invasive cultural heritage recovery

• Precise age dating through molecular shifting

Future missions are to combine the method with hyperspectral aerial mapping and penetrate deeper substrate zones (<12 m). Coupling with quantum resonance is also possible.nance tomographies are planned.
