| Text Description: |
Only present at Site A of Chester Bluff. Kandik River (KR) tephra has an orange hue, is up to 1 cm thick and has sharp upper and lower contacts. It is semi-continuous within massive loess across Site A and is locally deformed and faulted with some organic material. Contaminated by detrital material but also appear to be dominated by green amphibole and some ortho-pyroxene. The composition reported was calculated from analyses of seven samples: UA1059, UA1060, UA1068, UA1069, UT1676, UT1876, and UA1210. |
