- W2059596488 abstract "K – Ar dating of illite-bearing clays from eight locations in Jenolan Caves yielded ages from 394 Ma (Early Devonian) to 258 Ma (Late Permian) (18 dates of individual size fractions). There were two distinct clusters among the dates. Seven dates ranged from 342 to 335 Ma (Carboniferous, Visean). Three dates ranged from 394 to 389 Ma (Early Devonian). Fission track dating of 11 zircons from one sample yielded pooled ages of 345.9 Ma (nine grains) and 207.2 Ma (two grains). XRD peak width measurements and SEM studies indicated that the clays are well crystallised and showed no signs of transport. This suggests that the clays formed and matured in place in the caves. Sedimentary strata of Visean to Namurian age are not found in the surroundings of the caves. XRD peak width measurements, SEM studies, and additional K – Ar illite dating rule out illite-bearing materials in the immediate catchment of the caves as a source for the Carboniferous clays. The most likely origin for the Carboniferous clays is from volcaniclastics, associated with the emplacement of Carboniferous granites, entering the caves. The volcaniclastics reacted with thermal waters, which had excavated the caves, altering feldspars and glasses to kaolinite and illite. The Early Devonian clays are interpreted as volcaniclastic palaeokarst deposits related to an unconformity at the base of the overlying Lower Devonian volcanics. Whatever their origin, the Carboniferous clays are hundreds of millions of years older than absolute dates of cave deposits reported in recent reviews and appear to set a record for the absolute age of deposits found in currently open caves." @default.
