“…In some cases, cryptotephras are manifested as crystal (mineral) concentrations rather than, or in addition to, sparse glass shard concentrations (e.g. Hogg and McCraw, 1983;Lowe, 2011;Matsu'ura et al, 2011Matsu'ura et al, , 2012Matsu'ura et al, , 2014. Fig.…”

Layers of far-travelled volcanic ash (tephra) from explosive volcanic eruptions provide stratigraphic and numerical dating horizons in sedimentary and volcanic sequences. Such tephra layers may be dispersed over tens to thousands of kilometres from source, reaching far beyond individual volcanic regions. Tephrochronology is consequently a truly global dating tool, with applications increasingly widespread across a range of Quaternary and geoscience disciplines. This special issue of the International Focus Group on Tephrochronology and Volcanism (INTAV) showcases some of the many recent advances in tephrochronology, from methodological developments to diverse applications across volcanological, archaeological, and palaeoclimatological research.

“…Analyses by microprobe of ferromagnesian silicate minerals, such as biotite (Shane et al, 2003;Smith et al, 2011) and cummingtonite (Matsu'ura et al, 2012), apatite (a phosphate-group mineral) (Sell and Samson, 2011), and Fe-Ti oxides such as titanomagnetite and ilmenite (Shane, 1998;Preece et al, 2011b;Marcaida et al, 2014), have also been used for tephra fingerprinting. In some cases, and after taking into account compositional zoning within crystals, trace elements such as Mg, Cl, Mn, Fe, Ce, and Y identified in apatite crystals and phenocrysts provide a means of distinguishing or matching tephras (Sell and Samson, 2011).…”

Tephrochronology is the use of primary, characterized tephras or cryptotephras as chronostratigraphic marker beds to connect and synchronize geological, paleoenvironmental, or archaeological sequences or events, or soils/paleosols, and, uniquely, to transfer relative or numerical ages or dates to them using stratigraphic and age information together with mineralogical and geochemical compositional data, especially from individual glass-shard analyses, obtained for the tephra/cryptotephra deposits. To function as an age-equivalent correlation and chronostratigraphic dating tool, tephrochronology may be undertaken in three steps: (i) mapping and describing tephras and determining their stratigraphic relationships, (ii) characterizing tephras or cryptotephras in the laboratory, and (iii) dating them using a wide range of geochronological methods. Tephrochronology is also an important tool in volcanology, informing studies on volcanic petrology, volcano eruption histories and hazards, and volcano-climate forcing. Although limitations and challenges remain, multidisciplinary applications of tephrochronology continue to grow markedly.

“…It was also described from andesites of the Narcondam volcano in the Andaman Sea GEOLOGICA CARPATHICA, 2018, 69, 4, 335-346 (Pal et al 2007), from Iceland dacites at Króksfjördur volcano (Pedersen & Hald 1982), dacites from Martinique (d'Arco et al 1981), Japan tephras (Matsu'ura et al 2012) and other places. Moreover, the cummingtonite-bearing tephras are widely used in tephrostratigraphy (after Lowe & Hunt 2001), because they form only a low percentage of tephras and so can be used as correlation horizons (e.g., Matsu'ura et al 2012). This fact can also be used for provenance studies, for example, of cummingtonite-bearing tephras connected with Mount St. Helens (Smith & Leeman 1982;Mullineaux 1986).…”

Within the framework of reinterpretation of the depositional evolution of the Komjatice depression, presence of cummingtonite in weakly lithified sediment has been detected. The sediment is formed by volcanic lithoclasts and phenocrysts with a small admixture of non-volcanic grains. The different mineral composition and various degrees of alteration of volcanic lithoclasts, together with structural features point to epiclastic origin. Therefore, the studied samples can be described as volcanic paraconglomerate and sandstone. The cummingtonite is found in rusty coloured volcanic lithoclasts and in the heavy fraction. Cummingtonite-bearing volcanic rocks have not been described so far from the Slovak Neogene volcanic fields. Therefore its presence in the studied samples represents the first indication of such volcanic rock in Slovakia. The aim of the article is to invoke interest for finding these volcanic rocks in situ.
