“…The temperature of the overlain vesicular slag calculated from the olivine-bulk chemical composition is in the range of 1200-1350°C, while calculations based on the clinopyroxene-bulk chemical composition give 1140-1260°C (Warchulski 2015.). Puziewicz et al (2007) by analogy to rapidly cooled, but holocrystalline silica-undersaturated lavas assumed that low viscosity is the key factor causing crystallization of slagforming phases. In the border zone of the segregations the viscosity of the liquid increased due to the escape of volatiles into the cavities.…”

Mineralogy and origin of coarse-grained segregations in the pyrometallurgical Zn-Pb slags from Katowice-Wełnowiec (Poland)

The unique among pyrometallurgical slags, coarsegrained (up to 2.5 cm) segregations (up to 40 cm long) rimmed by Baplitic^border zones occur within holocrystalline historical Zn-smelting slag in Katowice, S Poland. Slag surrounding the segregations consists of olivine, spinel series, melilite, clinopyroxene, leucite, nepheline and sulphides. Ca-olivines, kalsilite and mica compositionally similar to oxykinoshitalite occur in border zones in addition to olivine, spinel series and melilite. Miarolitic and massive pegmatite-like segregations are built of subhedral crystals of melilite, leucite, spinel series, clinopyroxene and hematite. Melilite, clinopyroxenes and spinels in the segregations are enriched in Zn relatively to original slag and to fine-grained border zones. The segregations originated as a result of crystallization from residual melt rich in volatiles (presumably CO 2 ). The volatilerich melt was separated during fractional crystallization of molten slag under the cover of the overlying hot (ca. 1250°C) vesicular slag, preventing the escape of volatiles. That unique slag system is analogous to natural magmatic systems.
