- Gypsiferous Deposits on Sheep Mountain, Alaska
- From abstract: Gypsum-bearing rocks crop out in Gypsum and Yellow Jacket Gulches, on Sheep Mountain, which is about 90 miles northeast of Anchorage, Alaska. The gypsiferous rock occurs in deposits of irregular shape in the greenstone. Both the gypsiferous rock and the greenstone are hydrothermal alteration products of the volcanic rocks of Jurassic age which comprise the bulk of the mountain. Near-surface samples of the gypsiferous rock contained an average of 25 to 30 percent gypsum ; some contained as much as 50 percent. Quartz, alunite, clay, sericite, and pyrite are contaminating constituents of the ore. Six of the largest and most accessible of the gypsum deposits were mapped and calculations show that three of the deposits contain an aggregate of approximately 311,000 short tons of indicated gypsiferous rock and four of the deposits contain 348,000 short tons of inferred gypsiferous rock.

- Interim Report on the Radioactive Carbonate-Hematite Veins Near Salmon Bay, Prince of Wales Island, Southeastern Alaska
- From abstract: In the vicinity of Salmon Bay near the northeastern end of Prince of Wales Island, southeastern Alaska, samples obtained in 1951 from narrow, steeply dipping, carbonate-hematite veins contain as much as ,O.07 percent equivalent uranium. The average grade of these veins cannot be reliably stated because no systematic sampling has been done. No uranium or thorium minerals have been identified. Several chemical analyses indicate only a few thousandths percent uranium. Most of the radioactivity is apparently caused by thorium, which seems to be in or closely associated with red hematite.

- Lead-Alpha Age Determinations of Granitic Rocks from Alaska
- Abstract: "Lead-alpha activity age determinations were made on zircon from seven granitic rocks of central and southeastern Alaska. The results of the age determinations indicate two periods of igneous intrusion, one about 95 million years ago, during the Cretaceous period, and another about 53 million years ago, during the early part of the Tertiary. The individual ages determined on zircon from 2 rocks from southeastern Alaska and 1 from east-central Alaska gave results of 90, 100, and 96 million years; those determined on 4 rocks from central Alaska gave results of 47, 56, 58, and 51 million years."

- The Occurrence of Zeunerite at Brooks Mountains, Seward Peninsula, Alaska
- Abstract: Zeunerite occurs near the surface of a granite stock on the southwest flank of Brooks Mountain, Alaska. The largest deposit is at the Foggy Day prospect where zeunerite is disseminated in hematite which partially or totally fills openings and vugs in a highly oxidized lensshaped body of pegmatitic granite and to a minor extent in openings and cracks in the weathered granite enclosing the lens. Although a few specimens from the pegmatitic lens contain as high as 2.1 percent equivalent uranium, the overall average content of the lens rock is between 0.1 and 0.2 percent equivalent uranium and about 0.07 percent equivalent uranium for both the lens material and the surrounding zeunerite-bearing granite.
