摘要

在自然界中发现的多组分冷凝玻璃提供了对冷凝机制的深入了解，这些机制仍然不够充分。在月球陨石坑的撞击物中发现的冷凝玻璃含有纳米大小的金属铁、铬、铜、锌、银、银、碲、金、铂和铋，以及铁、铜和锌的硫化物。这种组合可能表明，具有如此不同逸度的组分几乎同时凝结的短暂凝结窗口，或可能的团簇凝结机制，只要这些团簇的凝结温度接近。

Condensate in Impact Glass Samples from the Lonar Crater, India

Polycomponent condensate glasses found in nature provide an insight into condensation mechanisms, which are still understood inadequately poorly. Condensate glasses found in the impactites of the Lonar crater contain nanosized inclusions of metallic Fe, Cr, Cu, Zn, Ag, In, Te, Au, Pt, and Bi, along with Fe, Cu, and Zn sulfides. This combination may be indicative either of a brief condensation window for the almost simultaneous condensation of components with so different fugacity or of a possible mechanism of cluster condensation, provided that the condensation temperatures of such clusters are close.

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.
