| Text Description: |
Associated with sands and gravels, but the stratigraphic identity of the host sediments is uncertain. The composition reported here is the average of two samples: UT1054, UT1455. Type II beds have more crystals than type I beds, and the glass is mainly in the form of highly inflated pumice. Feldspar, orthopyroxene, and green amphibole are common with minor or trace amounts of red amphibole, clinopyroxene, iron-titanium oxides, apatite, and zircon. |
