Provenance of heavy minerals in the Quaternary deposits of the Lemme outcrop, Estonia, based on optical microscopy, X-ray diffractometry and scanning electron microscope microanalysis

Autor: Johanna-Iisebel Järvelill, Toivo Kallaste, Anne Kleesment, Siim Pajusaar, Anto Raukas

Publikováno v: Estonian Journal of Earth Sciences, Vol 68, Iss 2, Pp 76-87 (2019)

This paper is a methodological development, where optical microscopy, X-ray diffractometry (XRD) and microanalysis under a scanning electron microscope (SEM) were used for comparative determination of heavy minerals in Quaternary sandy sediments in t

Correlation between radon release, radioactivity and mineralogy: a case study of Estonian black sands

Autor: Rein Koch, Alan H. Tkaczyk, Cagatay Ipbüker, Anne Serv, Zoltán Sas, Johanna-Iisebel Järvelill

Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 326:75-86

The growing attention to naturally occurring radionuclides in building materials has a significant societal impact. This impact is apparent in recent research studies and the latest European Council directives, where reference levels for indoor radon

Development of the Narva-Jõesuu beach, mineral composition of beach deposits and destruction of the pier, southeastern coast of the Gulf of Finland

Autor: Johanna-Iisebel Järvelill

Publikováno v: Open Geosciences, Vol 11, Iss 1, Pp 961-968 (2019)

Narva-Jõesuu lies at the eastern southeastern coast of the Gulf of Finland, at the Estonian and Russian border. The beach is influenced by heavy winds, waves and drift ice attacks, which are seriously changing the beach. It is the longest sandy beac

Hazardous radioactivity levels and heavy mineral concentrations in beach sediments of Lake Peipsi, northeastern Estonia

Autor: Tiit Vaasma, Anto Raukas, Johanna-Iisebel Järvelill, Rein Koch

Publikováno v: Geologos, Vol 24, Iss 1, Pp 1-12 (2018)

The present study discusses results of heavy mineral analyses and radioactivity of beach sediments of Lake Peipsi. Such analyses are commonly done globally, but had not yet been conducted for the fourth largest lake in Europe. The average heavy miner
