Fossils in Lava Mistaken for Minerals

Abstract

The sample reveals elongated, tube-like structures with internal partitioning that match the morphology and size range of wood cells from vascular plants. This article presents a detailed morphological analysis of these features and rebuts the abiotic interpretation, demonstrating that no known mineral growth or fracture pattern in igneous or metamorphic contexts replicates these biological signatures.

1. Cellular Geometry and Size Match Vascular Plant Wood Cells

The structures observed exhibit:
– Long, parallel, tube-like fibers.
– Slight periodic swellings (nodal thickenings).
– Straight cell walls and internal separations.

Measured against the scale bar, individual “cells” span:
– Widths of ~15–20 µm.
– Lengths from ~100 µm to >500 µm.

These dimensions fall squarely within the known range for fossil or modern wood cells.

2. No Known Mineral Can Mimic All Features

Common abiotic mineral structures that might be proposed include:
– Asbestos fibers or other fibrous silicates: these are chemically distinct, lack internal partitions, and do not exhibit the tapering, nodal patterns seen here.
– Fracture veins or tension cracks: these lack the uniform width and curvature.
– Crystallization textures: igneous mineral growth does not produce such consistently tubular, parallel strands with biological segmentation.

No standard mineralogical atlas shows anything with this level of morphological and structural correspondence to plant cells.

3. Preservation in a Volcanic Matrix Is Plausible

Skeptics may argue that volcanic settings are too hot for biological material to survive. However:
– This photo may represent material from altered volcanic ash, tuff, or basaltic deposits where soft sediment incorporation and rapid mineralization can preserve organic outlines.
– Silicification or carbonization may occur before cellular decay, particularly if plants were engulfed in cooler outer edges of flows or volcanic sediment.
– Known examples of fossil wood in basalt or volcanic tuff support this preservation route.

4. Structural Complexity Exceeds Random Abiotic Origin

Even if some crystal fibers or cracks superficially resemble tubes, the image shows:
– Repetition of aligned tube-like forms.
– Internal boundaries between “cells.”
– Occasional nodes or bulges suggesting pits or secondary wall thickenings.

Such organized complexity, especially at consistent scales, strongly exceeds what abiotic growths tend to produce without a biological template.

Conclusion

This image is best interpreted as a microscopic view of fossilized wood cells, likely tracheary elements, preserved in a volcanic or volcaniclastic matrix. The uniform cellular geometry, biologically consistent scale, and anatomical detail collectively argue for a biogenic origin.

The burden of proof now rests on the abiotic hypothesis: no known mineralogical structure offers an equally precise match.

Key Takeaway

These are not mineral artifacts. The features shown reflect organized, multicellular plant structures — and demand serious consideration as authentic microfossils.
