Early formation of K‐feldspar in shallow‐marine sediments at near‐surface temperatures (southern Israel): evidence from K‐Ar dating

Abstract: Authigenic K-feldspar was investigated in two Albian to Turonian sections in Israel using K-Ar and Ar-Ar dating, X-ray diffraction, scanning electron microscopy and chemical analysis. Both sections comprise a similar succession of shallow-marine limestones, dolomites and marls, with some sandstone and shale beds of continental origin. The HCl-insoluble residue fraction of the studied samples consists of clays, quartz, feldspars, goethite and trace amounts of heavy minerals. Most of the insoluble residues have … Show more

“…Moreover, secondary clays and zeolites, as well as feldspars, can form directly under ambient conditions or diagenetically by devitrification of silicate glasses (e.g., Kastner and Siever 1979;Sandler et al 2004;Meunier 2005).…”

“…The application of the K–Ar dating method for potassic authigenic minerals to determine the age of deposition or diagenetic events in sandstones is reported widely in the literature (Thomas, ; Hamilton, ; Banner, ; Maraschin and Mizusaki, ). The potassic authigenic minerals commonly used for age determinations are illite and mixed‐layer illite–smectite (Lee et al ., , ; Aronson and Douthitt, ; Macchi, ; Burley and Flisch, ; Hamilton et al ., , ; Mizusaki et al ., ; Barnes et al ., ; Clauer et al ., , ; Hogg et al ., ; Robinson et al ., ; Zwingmann et al ., , ; Pevear, ; Liewig and Clauer, ; Franks and Zwingmann, ; Maraschin et al ., ; Aubet et al ., ; Clauer, ; Clauer and Liewig, ), K‐feldspar overgrowths (Halliday and Mitchell, ; Girard et al ., ; Sandler et al ., ; Maraschin et al ., ) and glauconite (Montag and Seidemann, ; Amireh et al ., ; Kelly et al ., ; Duarte and Martínez, ; Rousset et al ., ; Gopalan, ).…”

“…Complete physical separation of authigenic and detrital phases has proved problematic, significantly hindering the analysis of bulk separates (Lee and Savin, 1985). Although some investigations have yielded sensible ages for authigenesis (Sandler et al, 2004), sample preparation is complex and unreliable. Complete separation of detrital and authigenic feldspar is difficult to verify.…”
