INCIPIENT SILICA CEMENTATION IN CENTRAL NEVADA ALLUVIAL SOILS INFLUENCED BY TEPHRA (DURIPAN, TAXONOMY, OPAL-CT, GENESIS).
Silica cemented pedogenic horizons known as duripans occur on relict landforms in climates having limited leaching potential. Under the influence of tephra, incipient silica cementation may also occur in late Quaternary soils. The source of silica for cementation in Holocene soils is rapidly weather...
