Text Description: Gold Run tephra occurs as white pods and lenses, up to 10 cm thick, in the upper part of a thick diamict, which is likely of colluvial origin. From Preece et al. (2011): 0.5 cm thick; pumice with rare blocky grains; in sand and silt; on strath 18 m above the Sixtymile River; 417 cm above top of bench gravel; field name JJO244. References: ![]() ![]() ![]() |
