Widmanstätten patterns are geometric textures observed in iron meteorites, widely attributed to phase separation and extremely slow cooling of nickel–iron alloys. The subject figure, originally described as displaying a Widmanstätten pattern, also reveals distinct strand-like substructures highlighted by red arrows and red lines. These substructures exhibit bounded geometries, uniform widths, and repeated modular architecture that do not conform to the planar lamellae expected in classical Widmanstätten structures. This article explores the morphological characteristics of these substructures and proposes that they may represent artificially manufactured elements incorporated within the meteorite, contributing to the observed pattern.

1. Introduction

Widmanstätten patterns are well-documented metallographic textures consisting of interwoven kamacite and taenite lamellae formed during very slow cooling of octahedrite iron meteorites. These patterns are routinely revealed by etching polished slices of meteoritic iron to make the interleaved bands visible. The presence of such patterns is considered diagnostic of extraterrestrial origin.(維基百科)

The figure under investigation was described as showing a Widmanstätten pattern. However, detailed inspection reveals additional organized substructures that are not immediately accounted for by classical metallurgical explanations. These features have prompted re-examination of the mechanisms responsible for the pattern and the possible role of non-natural processes.

2. Description of the Observed Features

The subject figure contains:

• Red arrows indicating localized linear or strand-like structures.

• Red lines marking assemblies of these strands forming extended pathways.

These features are visually distinguishable from the main lattice of intersecting lamellae traditionally described in Widmanstätten figures.

Characteristics of these substructures:

• Bounded geometry with finite terminations.

• Consistent modular widths across multiple occurrences.

• Aligned to form strand bundles rather than continuous planar plates.

• Compact, repeatable morphology.

Unlike typical Widmanstätten lamellae, which are planar and extend across the crystal domain dictated by crystallography, these strand-like elements appear as discrete segments that do not form continuous plates.

3. Widmanstätten Patterns in Iron Meteorites

Widmanstätten patterns arise when a homogeneous nickel–iron alloy in a meteorite cools sufficiently slowly (cooling rates on the order of 10–1,000 °C per million years) that a two-phase structure develops. Kamacite (low-nickel phase) precipitates along specific crystallographic directions within the taenite matrix, forming lamellae visible on polished and etched surfaces.(維基百科)

These planar lamellae have the following features:

• Growth along crystallographically defined planes.

• Intersections at characteristic angles determined by crystal symmetry.

• Thickness and spacing correlated with nickel content and cooling rate.

Such lamellae are typically large compared to microstructures seen in terrestrial alloys and represent diffusion-controlled growth over geological timescales.

4. Morphological Comparison

The strand-like features highlighted differ from classical lamellae in key ways:

• Discrete segmentation: Instead of extended plates, the features appear as short, bounded segments.

• Uniform modular width: While natural lamellae vary in thickness, these features maintain similar widths across occurrences.

• Bundle organization: Local clusters of strands form assemblies distinct from lattice geometry.

These differences suggest either an overlay of additional structure on top of the classical lamellae or the presence of embedded features that are not generated by slow cooling processes.

5. Hypothesis of Artificial Origin

Given the morphological distinctions noted above, this article explores the hypothesis that the highlighted strand-like elements may represent artificial constructs incorporated into the meteorite:

• The bounded and modular morphology resembles engineered conduits or structural strands.

• Their presence within a pattern otherwise attributed to natural cooling processes raises questions about exclusive geological interpretation.

• These substructures could serve as templates or inclusions around which the surrounding lattice crystallized, producing a composite pattern.

Such an interpretation does not deny the existence of natural Widmanstätten lamellae; rather, it suggests that the observed pattern may be a hybrid structure with contributions from pre-existing artificial elements.

6. Implications and Future Work

If certain meteorite patterns incorporate artificial elements, this would have significant implications for:

• Interpretation of meteoritic microtextures.

• Understanding of historical interactions between human or non-terrestrial technology and meteoritic materials.

• Criteria for distinguishing natural metallurgical features from manufactured structures in extraterrestrial contexts.

Future investigations should apply high-resolution imaging (e.g., SEM, EBSD) and compositional mapping (e.g., EDS) to determine whether the highlighted features exhibit chemical or crystallographic signatures inconsistent with classical Widmanstätten lamellae.

7. Conclusion

The subject figure combines a global pattern consistent with classical Widmanstätten structures and localized strand-like substructures that deviate from expected lamellar morphology. These deviations support the hypothesis that at least some observed features are artificial in origin, embedded within the meteorite and influencing the overall pattern. This hybrid interpretation expands the analytical framework for understanding complex meteoritic textures.
