Melt inclusions were investigated in the minerals of dacite tephra of the largest Holocene eruption (7900 years) of Khangar volcano, Sredinny Range of Kamchatka. Melt compositions correspond to rhyolite (SiO₂ = 70–77 wt %, Na₂O+K₂O = 6–7 wt %) with ~5 wt % H₂O. The melts show a minor negative Nb anomaly and lesser HREE depletion (La/Yb is ~7.1) compared to those of Ichinsky Volcano, another active volcano of the Sredinny Range of Kamchatka. It was determined that different phenocryst assemblages were formed within temperature ranges of 750–785 and 830–870°C. Evidence for the assimilation of granite-gneiss basement by magmas of Khangar volcano are discussed.

在堪察加火山Sredinny Range的最大的全新世喷发（7900年）的达菲特特非拉矿物中研究了熔体包裹体。熔体成分相当于流纹岩（SiO ₂ = 70-77 wt％，Na ₂ O + K ₂ O = 6-7 wt％），H ₂ O约为5 wt％。熔体显示出较小的负Nb异常和较少的HREE损耗（La / Yb为〜7.1），与堪察加半岛Sredinny Range的另一座活火山Ichinsky火山相比。已确定在750–785和830–870°C的温度范围内形成了不同的隐晶集合。讨论了Khangar火山岩浆吸收花岗岩-片麻岩基底的证据。
