The Biogeodynamic Unified Model: A 6-Phase Forensic Reconstruction of Martian Tectonic Evolution and the Dichotomy Riddle

Abstract This repository contains the complete computational framework, NASA telemetry inputs, and simulation outputs for the Biogeodynamic Unified Model. This 6-phase, GPU-accelerated geodynamic simulation (utilizing CuPy at 256³ and 512³ resolutions) bridges planetary physics and molecular biology. The model reconstructs the evolutionary trajectory of Mars, from the closure of the "Thermal Cage" and the subsequent biological metabolic pivot (the Nitrogenase transition), to the poroelastic venting of the crust driven by Chandler wobble, and finally, the resolution of the Martian Dichotomy via a "Radiogenic Capacitor" plume discharge. Methodology & The 6-Phase Pipeline This simulation is mathematically contiguous; the terminal state of each phase serves as the boundary condition for the next, eliminating arbitrary parameter tuning. Phases 1–3 (The Metabolic Pivot): Establishes the "Thermal Cage" threshold. As tectonic recycling arrests, transition metals (Mo, V) are sequestered, forcing the Martian biosphere into a deep-crustal Fe-only Nitrogenase pivot. Phase 4 (Poroelastic Venting): Validates the coupling between subsurface fracture permeability and observable atmospheric methane flux, modulated by Chandler wobble cyclic forcing. Phase 5 (The Gravity Handshake): Integrates NASA MRO Bouguer anomaly data (GGMRO_120) to isolate the Basal Mantle Layer (BML) and dense eclogite drip mass anomalies (the "Hidden Dog"). The terminal state records a BML depth of 0.0170 and an active, though insulated, core heat flux. Phase 6 (The Dichotomy Riddle): Initializes directly from Phase 5 telemetry. The model simulates the discharge of the deep-mantle radiogenic heat (the "Capacitor"), projecting a localized mantle plume against the MRO crustal thickness boundary to reconstruct the Tharsis Rise upthrust and the Vastitas Borealis basin. Methodological Transparency: Isostatic Calibration To ensure geophysical rigor, the Phase 6 topographic output applies a mandatory Airy Isostatic Compensation filter. The raw fluid-dynamic engine calculates a pre-isostatic tectonic subsidence (mechanical load) of -3500.00 m. By acknowledging that the Martian lithosphere is a floating, non-rigid system, the isostatic filter ($D_{iso} = D_{tectonic} \times [\rho_m - \rho_c] / \rho_m$) relaxes this load to an equilibrium deflection of -2674.05 m. This post-isostatic rebound closely converges with the observed Vastitas Borealis baseline (-2503.17 m, <7% residual), providing independent forensic validation of the model. Textural Porosity Scaling The model utilizes a "barley / barley bread" morphological texture baseline as a localized poroelastic flux modifier. This calibrates fluid resistance across the dichotomy boundary, linking observable surface textures to deep-crustal fracture permeability. Repository Structure The archive is organized to ensure full scientific reproducibility and a clear chain of custody for all data: 01_Source_Code/: Contains the Python/CuPy solvers (Phase5_GeodynamicEngine.py, Phase6_DichotomySolver.py, etc.). 02_Telemetry_and_Logs/: The JSON state files connecting the phases (e.g., 02_Telemetry_P5_GeodynamicState.json), proving the model's contiguous execution, alongside raw console logs. 03_Input_Data_NASA_MRO/: The 64-bit Little-Endian binary grids (.img and .lbl) from the NASA Planetary Data System (GGMRO_120 crustal thickness and Bouguer anomalies) used as static boundary conditions. 04_Results/: High-resolution visual outputs of the calibrated topographic upthrust and residual gravity maps.
