The chemistry of eolian quartz dust and the origin of chert
C. Blaine Cecil, Bruce Hemingway, Frank T. Dulong
2018, Journal of Sedimentary Research (88) 743-752
Among the numerous models that have been suggested for the primary and predominant source of silica for chert, we suggest that eolian dust is worthy of further considerations. Such considerations are supported by the common association of Phanerozoic chert with evaporites, limestones, dolomites, or other strata that were deposited within...
