Abstract
Harold Lloyd James is widely recognized for his trail-blazing interpretations of the field relationships and petrology of the metamorphosed and structurally complex iron-rich sedimentary rocks known as “iron-formation.” Although his research focused on northern Michigan, the fundamental contributions he made there have proven applicable worldwide for the sedimentary iron deposits that constitute the bulk of the world’s iron ore resources. Prior to James’ work, the unusual chemical and mineralogical character of iron-formation was attributed to metamorphism and hydrothermal alteration of iron-rich carbonate sedimentary rocks. However, James peered through the veil of metamorphism and subsequent local oxidation, unraveling the spatial relations among lithologies, recognizing features that distinguished their protoliths, deciphering their primary igneous and sedimentary patterns, understanding their structural and petrogenic affiliations, and showing that the iron-rich assemblages of rocks exhibit a systematic and oft-repeated sequence of intergradational facies that reflect the integrated sedimentary environments of ancient marine basins. That reconstruction provides a powerful tool to locate the economically important oxide facies rocks that represent the principal economic targets, and to unravel structural complexities in terrains containing iron-formation. His constructive influence extended far beyond his own scientific work as friend, mentor, and colleague to many associates, as an active member of the geologic community, and culminating in service (1965–1971) as Chief Geologist of the United States Geological Survey. Harold Lloyd James (known to his many friends and colleagues as Hal) was born on June 11, 1912 in Nanaimo, British Columbia, the eldest of five children of Evan and Blodwen James who had emigrated from Wales in 1911. The family moved to Bellingham, Washington in 1923, and his naturalization was completed in 1940. Hal attended public schools in Nanaimo and Bellingham and graduated from the latter’s Whatcom High School in 1933 at the age of 20, having spent six years of full-time …

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
