Abstract

The paper presents experimental results on the solubility of fluorides in fluid-saturated melt of alkaline ultrapotassic syenite-porphyry from the Gross gold ore deposit in southern Yakutia at T = 600–800°C, P = 150–260 MPa. The experiments were carried out to confirm the assumption of high solubility of fluorine in ultrapotassic syenite melt, which could contribute to the formation of specific and low-viscosity melts that were emplaced in the form of a syenite porphyry sill. The solid products after the experiments contained aluminosilicate glass, potassium feldspar, fluorite, quartz, and two fluoride phases differing in composition (potassium and aluminum fluoride and potassium and magnesium fluoride). The experimental results led us to determine a high maximum solubility of fluorine in the melt: up to 4.2–4.6 wt %, with the maximum F content found in the lowest temperature melt at 625°C. The solidus and liquidus temperatures of the syenite melt were estimated at 600–625 and 650–800°C, respectively. The aqueous fluoride fluid coexisting in equilibrium with the melt was determined to be alkaline. Potassium feldspar was the first to crystallize from the melt in the experiments, which is consistent with what is observed in samples of the naturally occurring rocks.

饱和钾正长岩熔体中氟化物溶解度的实验研究
本文介绍了在T = 600 ~ 800℃,P = 150 ~ 260 MPa条件下,南雅库特Gross金矿床碱性超经典正长斑岩流体饱和熔体中氟化物溶解度的实验结果。实验证实了氟在超典型正长岩熔体中的高溶解度假设,这可能有助于形成特定的低粘度熔体,并以正长斑岩的形式放置。实验后的固体产物包括铝硅酸盐玻璃、钾长石、萤石、石英和两种不同组成的氟相(氟化钾铝和氟化钾镁)。实验结果使我们确定了熔体中氟的最大溶解度:高达4.2-4.6 wt %,在625°C的最低温度熔体中发现最大F含量。正长岩熔体的固相温度和液相温度分别为600 ~ 625℃和650 ~ 800℃。测定了与熔体平衡共存的氟水为碱性。钾长石在实验中首先从熔体中结晶,这与在自然形成的岩石样本中观察到的结果一致。

期刊介绍: Petrology is a journal of magmatic, metamorphic, and experimental petrology, mineralogy, and geochemistry. The journal offers comprehensive information on all multidisciplinary aspects of theoretical, experimental, and applied petrology. By giving special consideration to studies on the petrography of different regions of the former Soviet Union, Petrology provides readers with a unique opportunity to refine their understanding of the geology of the vast territory of the Eurasian continent. The journal welcomes manuscripts from all countries in the English or Russian language.
