Reconnaissance geology, mineral occurrences, and geochemical anomalies of the Yentna district, Alaska
Allen L. Clark, C.C. Hawley
1968, Open-File Report 68-35
The Yentna district, in south-central Alaska, is underlain by slightly metamorphosed Mesozoic sedimentary rocks, and by sandstones, conglomerates and coaly minerals of the Tertiary Kenai Formation. The bedrock is locally covered by extensive surficial deposits of Quaternary and Recent (Holocene) age. The Mesozoic strata are cut by a quartz monzonite...

1968, Open-File Report 68-101
Anomalous gold values have been discovered in hydrothermally altered quartz diorite, quartz monzonite, and quartz mica schist at the head of Fox Creek; and in similarly altered quartz diorite in the Granite Creek area. Channel samples across some of these altered zones have produced anomalous gold values over widths which...
