Sample Detail of
Sample: Sample No. 69LG6
Locality: Field No. 69LG6
Description: Southwest cost of Amchitatka Island, "southwest Clevenger Lake", collected by R. H. Morris and L. M. Gard, 1969
Location: Alaska Quadrangle: Rat Islands
Lat.: 51o22'40 " Long.: 179o13'10 "

Title: Report on Referred Fossils ,  1969 (08/13)
Report by: Richard L. Pierce
Referred by: L. M. Gard
Age: Late Eocene-Oligocene
Formation: Banjo Point Formation
Comment:Problem: Banjo Point Formation assigned Oligocene or Miocene age by Powers et al. (Bull. 1028P) and Oligocene(?) age by MacNeil (Prof. Paper 553). This is one of several new collecting localities. Hopefully these rocks contain microfossils which will help to determine the age of the Banjo Point Formation with precision.
Age: If Foraminifera are in place, probably late Eocene or Oligocene, possibly late Eocene or early Oligocene. Paleobathymetry: Probaly bathyal depths. Remarks: The fauna is characteristic of both shelf and slope faunas with the shelf fauna probably being displaced.

Age: No Data
Formation: Banjo Point Formation
Comment:The fragmentary specimens in this collection are too poorly preserved and incomplete to shed any new light on the age of the Banjo Point Formation. The best evidence of age of this formation is furnished by the previous records of Chlamys washburnei (Arnold) (in MacNeil, F. S., USGS Prof. Paper 553, 1967, p. 36-37) which suggest a pre-late Oligocene age.
The association of taxa suggests a very shallow water environment but the condition of the fossils could indicate displacement from the original site of deposition.
