Organic facies characteristics of the Sivas Tertiary Basin (Turkey)

CO2 sequestration and extreme Mg depletion in serpentinized peridotite clasts from the Devonian Solund basin, SW-Norway

“…Therefore, according to our findings the ideal sequestration site for CO 2 under the specific alteration conditions in the Solund basin will be a weathered peridotite in combination with a Ca-source (e.g., plagioclase, clinopyroxene) which facilitates infiltration of a CO 2 -bearing fluid and fast precipitation of carbonate as calcite. Besides the Solund basin, field sites meeting these criteria can generally be expected in all sedimentary basins adjacent to ophiolite complexes as the Sivas basin in central Turkey where similar samples have been described by e.g., Altunsoy and Ozcelik (1998), the Deliler and Erenler basins of NW Turkey (Okay et al, 2008), or in sedimentary basins receiving ultramafic detritus from other, e.g., volcanic sources.…”

Gypsum karst and its evolution east of Hafik (Sivas, Turkey)

“…The basin was developed unconformably on a foundered Paleozoic-Mesozoic basement and on Eocene-Oligocene deposits (Fig. 2) (Kurtman, 1973;Poisson et al, 1997;Aktimur, 1988;Altunsoy and Ö zçelik, 1998;Ç iner et al, 2002;Gü nay, 2002;Koşun and Ç iner, 2002).…”

Discussion on geobiology, biogeology and geobiofacies

“…In many such researches, organic facies are mainly based on organic geochemistry indices [26,27] . Others emphasize sedimentary organic facies, which are defined for the potential source rocks based on sedimentary environments, biotic assemblages, redox conditions, diagenesis circumstances together with indices of organic geochemistry [28][29][30][31][32][33] .…”
