| Result | CHEMICAL ANALYSES SHOW THAT SILICA RANGES FROM 36 TO 61 PER CENT, AND TOTAL IRON FROM 25 TO 46 PER CENT (AVERAGE OF 34 PER CENT). FE2O3 CONTENT EXCEEDS FEO |
|---|---|
| Result | THIS RATIO IS THE OPPOSITE OF THAT IN MOST OTHER LARGE DEPOSITS OF BANDED IRON-FORMATION. AVERAGE CONTENT OF P2O5 IS 0.17 PERCENT, RESULTING IN ORE THAT IS DETRIMENTAL TO STEELMAKING. |

| Structure description | Two Aeromagnetic Anomalies, Each 5 To 10 Km Wide And With Positive Amplitudes Of 600 To 3000 Gammas, Extend West From Mount Ruker For 120 And 180 Km Under Glacial Ice. These Anomalies Almost Certainly Indicate Additionaal Iron Deposits. |
| Type of structure | Local |
| Structure description | Main Sequence Nearly 400 M Thick; Overlain And Underlain By Sequences, Each Over 300 M Thick, In Which Banded Iron Fm Is Less Abundant Than Other Rock Types. |

| Deposit | BEDS OF BANDED IRON-FORMATION (JASPILITE) CONSIST OF 0.1- TO 2-CM-THICK, CRINKLED, ALTERNATING LAMINAE OF QUARTZITE AND DARK-GRAY AND PURPLISH-BLACK OPAQUE MINERALS OF THE SUPERIOR TYPE. MAGNETITE IS MORE ABUNDANT THAN HEMATITIE IN THE OPAQUE FRACTION, AND ILMENITE LOCALLY REPLACES BOTH. |
