Stratigraphic Pattern Recognition & Paleoclimatic Temporal Reconstruction
A Physics-Informed AI Framework for Deep-Time Earth System Reconstruction, Stratigraphic Layer Intelligence, and Paleoclimatic Cycle Decoding
A unified cipher for Earth's geological memory
Beneath the Saharan sand, beneath the limestone karst of the Dolomites, beneath the floor of the Pacific Ocean, the Earth has been keeping a record — not of words or numbers, but of chemistry, mineralogy, magnetism, and biology. STRATICA is the first unified, multi-parameter Physics-Informed AI framework to decode, model, and read the stratigraphic record at the scale it operates: every isotope ratio, every fossil assemblage, every magnetic reversal preserved in sedimentary layers encoding the state of Earth's climate, chemistry, and life across 4.5 billion years.
STRATICA integrates nine analytically independent stratigraphic and geochemical parameters into a single Temporal Climate Integrity Index (TCI), embedded within a Physics-Informed Neural Network that enforces stratigraphic superposition, thermodynamic consistency, and orbital phase coherence as differentiable constraints throughout the computational pipeline. A defining innovation is its application of temporal back-casting — deploying deep-learning Transformer-LSTM hybrid architectures not to predict the future but to reconstruct the past, filling gaps in the geological record with physically constrained estimates.
Nine independent parameters unified into a single composite metric
TCI = 0.20·LDR + 0.15·ISO + 0.12·MFA + 0.11·MAG + 0.10·GCH
+ 0.09·PYS + 0.08·VSI + 0.08·TDM + 0.07·CEC
Each parameter φᵢ ∈ [0,1] normalized and weighted by Bayesian-optimized coefficients
TCI ranges: [0.00 = non-functional] to [1.00 = optimal fidelity]
Functional threshold: TCI > 0.62 (±50 kyr temporal resolution)
Each dimension of Earth system history, measured precisely
Five operational states of paleoclimatic reconstruction quality

The Paleocene-Eocene Thermal Maximum — Earth's most rapid carbon perturbation in 66 million years
The STRATICA TCI analysis of ODP Site 1209B at Shatsky Rise (North Pacific) demonstrates the framework's capability to reconstruct rapid climate transitions and constrain Earth System Sensitivity with unprecedented precision.
The multi-site STRATICA inversion across 7 PETM sites yields unprecedented constraints on carbon release rate and Earth System Sensitivity significantly higher than Pleistocene-derived estimates. This capability transforms paleoclimate science into a predictive discipline.
