Fire Sphere Cycle (FSC) Earth System Coupling Model: A Unified Framework for Interpreting Life Origin and Evolution, Algal Productivity, Fossil Energy Enrichment, and Global Marine Mass Extinctions

The Fire-Sediment Cycle (FSC) model proposes a unified Earth system framework linking life origin, Phanerozoic mass extinctions, and fossil energy accumulation to periodic paleowildfire activity. The model identifies wildfire as a planetary-scale endogenous regulatory agent, driv...

Aquatic Algal Mat-Driven Precursor Fire Sphere Cycle (FSC) Hypothesis

The long-standing absence of terrestrial photosynthetic fossils in pre-Devonian strata has led to the conventional view that continental interiors were barren of life during the Archean to Cambrian. This study challenges this view by proposing the Waterborne Soft Algal Mats Pre-F...
