Chitinozoans of the Margachitina margaritana Biozone and the Llandovery–Wenlock boundary in West Estonian drill cores 西爱沙尼亚岩心中Margachitina margaritana生物带和Llandovery-Wenlock边界的几丁质动物

{"title":"Chitinozoans of the Margachitina margaritana Biozone and the Llandovery–Wenlock boundary in West Estonian drill cores","authors":"V. Nestor","doi":"10.3176/geol.2005.2.02","DOIUrl":"https://doi.org/10.3176/geol.2005.2.02","url":null,"abstract":". The succession of chitinozoan taxa in the uppermost Llandovery and lowermost Wenlock of the Viki, Ohesaare, Kaugatuma, and Ruhnu drill core sections is described and correlated with the global stratotype section of the basal Wenlock in Hughley Brook, Shropshire, England. The most important biomarkers for the identification of the Llandovery(cid:150)Wenlock boundary in Estonian sections are the disappearance levels of Ramochitina nestorae , Conochitina acuminata , C . cf. flamma , and Angochitina longicollis . In the West Estonian cores this boundary corresponds to a level in the middle or upper part of the Margachitina margaritana Biozone. In the Viki and Ohesaare cores it coincides with the bentonite layers above the accepted boundary between the Adavere and Jaani regional stages and correlates with a level in the middle of the murchisoni graptolite Biozone. Three new species, Belonechitina oeselensis , Ancyrochitina mullinsi , and Eisenackitina inanulifera , are described.","PeriodicalId":237994,"journal":{"name":"Proceedings of the Estonian Academy of Sciences.

The stimulation/excitation spectra of the afterglow of the samples were recorded in the wavelength range of 250 -1100 nm. The results of the study show that these spectra present either excitation spectra of Mn 2+ ion fluorescence (samples of calcites and Iceland spar, red emission recorded) or the excitation spectra of primary phosphorescence (samples of carbonates, including mollusc shells; short-wave emission bands recorded). The recorded stimulation spectra revealed no spectral bands sensitive to stimulation by ionizing radiation, which would disappear as a result of heating and could thus be related to deep traps in carbonates, needed in dating. The causes of this situation which is unusual in luminescent crystals, including luminescence (palaeo)dosimeters, and the ways of overcoming the difficulties in optical dating of natural carbonates are discussed.","PeriodicalId":237994,"journal":{"name":"Proceedings of the Estonian Academy of Sciences.
