摘要

研究了罗马尼亚Baia Sprie Laleaua albuei英安岩矿物中的晶体包裹体(斜长石、黑云母、磁铁矿)和熔融包裹体。对斜长石、钾长石和石英中29个熔体的电子探针分析证实,这些矿物的结晶发生在典型的富钾(K2O/Na2O = 1.5)硅熔体中。产岩组分的总和为92% ~ 99%。这表明在结晶过程中,水分含量可能从8%变化到1%。通过离子探针对11个熔体包裹体进行分析,发现其最小含水量为0.5 wt%,最大含水量为6.1 wt%。其中一个熔体包裹体中存在高密度的水流体偏析,表明熔体中的初级含水量可达8.4%。离子探针数据显示,铜的浓度很高(高达1260 ppm), U的含量也较高(从5.0到14.3 ppm;在一些熔体夹杂物中平均11.5 ppm),相比之下…

Erratum to: Origin of the Laleaua Albă dacite (Baia Sprie volcanic area and Au-Pb-Zn ore district, Romania): evidence from study of melt inclusions
Crystal inclusions (plagioclase, biotite, magnetite) and melt inclusions were studied in minerals of the Laleaua Albă dacite (Baia Sprie, Romania). Electron microprobe analysis of 29 melt inclusions in the plagioclase, K-feldspar, and quartz confirm that crystallization of these minerals took place from typical silicic melts enriched in potassium relative to sodium (K2O/Na2O = 1.5). The sum of the petrogenic components is 92–99 wt%. This points to a possible change in water content from 8 to 1 wt% during crystallization of phenocrysts. According to ion microprobe analysis of 11 melt inclusions, the minimum water content is 0.5 wt%, and the maximum water content is 6.1 wt%. The presence of high-density water fluid segregation in one of the melt inclusions suggests that the primary water content in the melt could reach 8.4 wt%. Ion microprobe data revealed a high concentration of Cu (up to 1260 ppm) as well as higher U content (from 5.0 to 14.3 ppm; average 11.5 ppm) in some melt inclusions as compared to t...
