Rectilinear, compartmental “boxwork” structures observed on exposed Martian rock surfaces are widely labeled as geological by default. This article evaluates that attribution against strict observational constraints—surface exposure, lithified context, three-dimensional relief, geometric order, and areal repetition. When these constraints are applied simultaneously, no direct photographic or field evidence demonstrates that known natural geological processes produce equivalent structures under Earth conditions. This work shows that the natural-origin claim has not been validated.

1. Introduction

“Boxwork” is a descriptive term, not an explanation. On Mars, it has been used to denote surface patterns composed of rigid, rectilinear compartments resembling grids or frameworks. In practice, the label “geological” is often treated as settled fact rather than as a hypothesis requiring empirical support.

The purpose of this article is limited and precise: to assess whether a natural geological origin for boxwork on Mars has been demonstrated by evidence. The question is not whether geology could plausibly generate such structures in principle, but whether it has been shown to do so in the observed context.

Any explanation must account for the following properties as a single set:

1. Surface Exposure
   Boxwork occurs on open, exposed rock pavements, not on cave walls, void interiors, or fracture faces.

2. Lithified Context
   The structures are integral to solid bedrock, not to unconsolidated sediment or soil.

3. Three-Dimensional Relief
   Compartment walls show persistent edges and shadows, indicating real depth and rigidity rather than color contrast or superficial staining.

4. Geometric Order
   Compartments are rectilinear with frequent near-right-angle intersections. In multiple cases, square and circular forms coexist at the same scale.

5. Areal Repetition
   Numerous adjacent compartments form laterally continuous fields, not isolated or sporadic features.

These constraints are observationally grounded and non-negotiable. Partial matches are insufficient.

Natural origin is typically defended by analogy. When the most frequently cited analogues are examined against the constraints above, each fails in specific, repeatable ways.

3.1 Cave Boxwork

Cave boxwork forms on the walls of voids through secondary mineral growth. The environment, orientation, and exposure are fundamentally different from open Martian pavements.

Failure: wrong context.

These features form in unlithified sediment and consist of cracks rather than rigid, load-bearing walls. Their characteristic scale is orders of magnitude larger.

Failure: wrong material state and scale.

Jointing reflects regional stress fields and typically produces variable spacing and irregular geometry. No field photographs demonstrate fracture processes producing rigid, rectilinear, laterally extensive boxwork on exposed pavements with the observed coherence.

Failure: lack of demonstrated field equivalence.

Evaporites can display rectilinear internal fabrics and circular dissolution features. However, these are internal textures observed in cut or polished material. No documented examples show such frameworks preserved as naturally exposed rock pavements.

Failure: internal fabric, not surface expression.

Prepared sections can show small-scale rectilinear features with depth. Preparation, however, creates an artificial exposure context and cannot substitute for natural field documentation.

Failure: not a natural surface.

Despite decades of geological study, no Earth photographs have been presented that show:

• a naturally exposed rock surface,

• composed of lithified bedrock,

• bearing rigid, rectilinear boxwork,

• extending laterally across a pavement,

• matching the observed Martian geometry and repetition.

Geological explanations therefore rely on the assertion that known processes could generate such patterns. Plausibility is not evidence.

In standard geological practice, robust interpretations are supported by field analogues and repeatable documentation. For boxwork on Mars, the conclusion (“geological”) precedes the proof. The evidentiary chain stops at analogy.

This does not establish impossibility. It establishes non-demonstration.

This article does not claim that a natural origin is impossible. It shows that:

• no geological process has been empirically shown to produce the observed Martian boxwork in the required surface context, and

• therefore, claims that boxwork on Mars is already explained by geology are unsupported.

In scientific terms, the natural-origin hypothesis has not been validated.

To substantiate a natural origin, at least one of the following must be provided:

1. Documented terrestrial field photographs of surface-exposed, lithified boxwork matching the Martian observations.

2. Mineralogical and microstructural continuity demonstrating that boxwork walls and host rock share an origin inconsistent with construction or assembly.

3. Quantitative models predicting the observed geometry and repetition without ad hoc assumptions.

Until then, confident attribution to a natural geological origin is premature.

There is currently no direct photographic or field evidence demonstrating that known natural geological processes produce boxwork equivalent to that observed on exposed Martian rock surfaces.
