摘要:

X-ray radiographs of loess on Banks Peninsula revealed microstratification and features attributable to paleosols. The microstratification is inferred to reflect episodes of aeolian deposition. Use of X-ray radiography is recommended for engineering studies and determination of the geological history of loess successions.

摘要:

New evidence for the source of Taupo Pumice Formation includes orientation of charred logs, distribution of pumice and lithic material, absence of ballstic lithics, and bathymetry of Lake Taupo. All these clearly suggest an origin within eastern Lake Taupo, most probably at Horomatangi Reefs. No new evidence was found to substantiate sources beyond Lake Taupo.
