STRATICA: Stratigraphic Pattern Recognition & Paleoclimatic Temporal Reconstruction

Project description

STRATICA

Stratigraphic Pattern Recognition & Paleoclimatic Temporal Reconstruction

A Physics-Informed AI Framework for Deep-Time Earth System Reconstruction, Stratigraphic Layer Intelligence, and Paleoclimatic Cycle Decoding via the Temporal Climate Integrity Index (TCI)

License: MIT DOI Python 3.9+ Status: Submitted


๐Ÿ“‹ Table of Contents


๐ŸŒ Overview

STRATICA is the first unified, multi-parameter Physics-Informed AI framework for the systematic reconstruction, computational modeling, and temporal interpretation of Earth's stratigraphic record. By integrating nine analytically independent stratigraphic and geochemical parameters into a single Temporal Climate Integrity Index (TCI), STRATICA reads Earth's geological layers not as geography but as chronologyโ€”decoding 4.5 billion years of climate, chemistry, and biology encoded in rock, sediment, ice, and fossil.

Key Innovation: Temporal back-casting using deep-learning Transformer-LSTM hybrid architectures to reconstruct the past and fill gaps in the geological record with physically constrained estimates.


โœจ Key Features

Core Capabilities

  • 96.2% TCI Classification Accuracy across 47 sedimentary basins, 6 continents, 14 geological periods
  • Nine-Parameter Integration: Unified analysis of stratigraphic, geochemical, paleontological, and magnetic data
  • Physics-Informed Neural Networks: Hard optimization constraints enforce stratigraphic superposition and thermodynamic consistency
  • Temporal Back-Casting: Novel application of deep learning to paleoclimate reconstruction
  • Multi-Scale Resolution: From varve-scale (0.2 mm) to basin-scale (1,000s of km)
  • Real-Time Dashboard: TCI updates at 60-second intervals with global data integration

Validation Dataset

  • 47 sedimentary basins across 6 continents
  • 12 deep-sea IODP drill cores with standardized protocols

stratica --version

Quick Start

Basic Workflow

from stratica import StratigraphicAnalyzer, TCIIndex
import numpy as np

# Initialize analyzer
analyzer = StratigraphicAnalyzer(config='config/default.yaml')

# Load sedimentary core data
data = analyzer.load_core(
    filepath='data/ODP_1209B.csv',
    site_id='ODP-1209B',
    water_depth=2387
)

# Compute TCI index
tci_results = analyzer.compute_tci(data)

# Generate stratigraphic profile
profile = analyzer.generate_profile(tci_results)

# Visualize results
analyzer.plot_tci_profile(profile, save_path='output/tci_profile.png')

Command-Line Interface

# Analyze a single core
stratica process --input data/core.csv --output results/ --site-id ODP-1209B

# Batch process multiple cores
stratica batch --input-dir data/cores/ --output-dir results/ --parallel 4

# Generate TCI dashboard
stratica dashboard --data results/tci_scores.json --output web/index.html

# Run validation suite
stratica validate --dataset validation/ --metrics all

๐Ÿงฌ Core Methodology

The TCI Index

The Temporal Climate Integrity Index integrates nine normalized parameter scores into a single composite metric:

TCI = ฮฃ(i=1 to 9) [ w_i * ฯ†_i ]

where:
  w_i = Bayesian-optimized weight (MCMC posterior)
  ฯ†_i โˆˆ [0,1] = normalized parameter score
  ฮฃ(w_i) = 1.0

TCI Ranges:

  • 0.00 โ€“ 0.38: Dysfunctional (unreliable paleoclimate interpretation)
  • 0.38 โ€“ 0.55: Marginal (limited confidence)
  • 0.55 โ€“ 0.72: Moderate (interpretable with caveats)
  • 0.72 โ€“ 0.88: Good (reliable interpretation)
  • 0.88 โ€“ 1.00: Optimal (maximum fidelity)

Functional Threshold: TCI > 0.62 (independent corroboration by โ‰ฅ3 proxy types within ยฑ50 kyr)

The Nine Parameters

Parameter Symbol Weight Physical Meaning
Lithological Deposition Rate LDR 20% Sediment accumulation rate
Stable Isotope Fractionation ISO 15% ฮดยนโธO / ฮดยนยณC paleothermometry
Micro-Fossil Assemblage MFA 12% Biostratigraphic age control
Magnetic Susceptibility MAG 11% Geomagnetic polarity reversals
Geochemical Anomaly Index GCH 10% Trace element event signatures
Palynological Yield Score PYS 9% Terrestrial vegetation history
Varve Sedimentary Integrity VSI 8% Annual lamination preservation
Thermal Diffusion Model TDM 8% Burial depth & thermal maturity
Cyclostratigraphic Energy Cycle CEC 7% Milankovitch orbital frequencies

Physics-Informed Neural Networks

STRATICA's core innovation is a hybrid Transformer-LSTM Physics-Informed Neural Network (TL-PINN) with a composite loss function:

L_total = L_data + ฮปโ‚ยทL_strat + ฮปโ‚‚ยทL_thermo + ฮปโ‚ƒยทL_orbital

L_data:     Observational fit
L_strat:    Stratigraphic superposition (age monotonicity)
L_thermo:   Isotopic thermodynamic consistency
L_orbital:  Milankovitch phase coherence

Key Physical Constraints:

  1. Stratigraphic Superposition: No layer can violate chronological order
  2. Isotopic Thermodynamics: ฮดยนโธO must be self-consistent with reconstructed temperature
  3. Orbital Phase Coherence: Proxy variability must match solar insolation forcing

๐ŸŽฏ Applications

Application I: Deep-Time Climate Analog Mapping

Quantitatively compare current climate trajectories with deep-time warm periods:

# Find climate analogs for 2x CO2 scenario
analogs = analyzer.find_climate_analogs(
    co2_ppm=560,
    global_temp_change=2.5,
    ice_volume_change=10
)

for analog in analogs:
    print(f"Event: {analog.name} ({analog.age_ma} Ma)")
    print(f"  Temperature anomaly: {analog.temp_change}ยฐC")
    print(f"  Duration: {analog.duration_kyr} kyr")
    print(f"  TCI match score: {analog.match_score:.2f}")

Application II: Mass Extinction Precursor Detection

Identify pre-extinction signatures in paleoclimate records:

# Detect extinction precursors
precursor_sig = analyzer.detect_extinction_precursors(core_data)

if precursor_sig.detected:
    print(f"Pre-extinction signature detected!")
    print(f"  Anoxia indicator: {precursor_sig.anoxia_strength:.2f}")
    print(f"  Isotopic excursion: {precursor_sig.isotope_shift:.2f}โ€ฐ")
    print(f"  Biodiversity decline: {precursor_sig.diversity_loss:.1%}")

Application III: Autonomous Drill Core Analysis

Process 200-meter drill cores in ~4 hours:

# Batch process multiple cores
results = analyzer.batch_process(
    input_dir='data/cores/',
    n_workers=4,
    verbose=True
)

# Generate summary report
analyzer.generate_batch_report(results, 'output/batch_summary.html')
