Abstract On February 13, 2023, a huge fireball was visible over Western Europe (fireball event 2023 CX 1 ). After the possible strewn field calculated, first of several recovered samples, with mass about 100 g, discovered just 2 days after on ground village Saint‐Pierre‐le‐Viger. Meanwhile, more than 60 samples total kg were and piece one these is studied here. The fall occurred 220 years histo...

Abstract The paper considers the relationship between textural and structural features gross mineral chemical composition of minerals physical properties apatite-nepheline ores their processing. It is noted that change in involves primarily due to apatite depletion. An increase content nepheline pyroxene 35-55 % sharply increases ore strength up 47-104 MPa, which entails growth energy consumpti...

[1] We have investigated the effects of crystallization and oxidation on the visible and nearinfrared (VISNIR) and mid-infrared (mid-IR) spectra of materials with a Shergotty-NakhlaChassigny (SNC) basaltic composition in order to investigate potential links between Martian VISNIR spectra, Martian mid-IR spectra, and SNC meteorite data. SNC basalt samples of varying crystallinities were synthesi...

Introduction: Frequent impacts [e.g., 1-3] reworked the crust of Mars during the Noachian [4]. The energy of those impacts created thousands of prominent heat sources that supported long-lived, deep-reaching hydrothermal systems [5,6]. In this paper, we investigate how those systems altered the chemistry and mineralogy of Noachian crust. Previous work and motivation for this study: We previousl...

Groundmass pyroxene crystals in pumice from the 1914 eruption of Sakurajima Japan show varied combinations crystallographic faces (i.e., ‘tracht’). To investigate whether groundmass tracht depends on magma decompression conditions, we performed isothermal single–step experiments hydrous dacite magma. The was held under water–saturated conditions at 920 °C, 120 MPa, and oxygen fugacity no more o...
