Abstract

In this study, boron contents and boron isotopic compositions of geothermal waters are first reported in the Xianshuihe Fault Zone (XSHFZ), Western Sichuan. The results show that boron contents of geothermal water are 0.03-10.50 mg/L, and the δ11B values range from -6.75 to 4.01‰, indicating the non-marine origin. The δ11B values and Cl/B molar ratios reveal that boron in geothermal water is mainly leached from reservoir rocks, such as carbonate and igneous rocks. Comparing it with other geothermal systems in the Yunnan-Tibet Geothermal Belt, we found that the samples from XSHF have the largest variations of Cl/B molar ratio and the intermediate δ11B values.

Abstract

In order to study the light ∞ash radiant intensity produced by strong shock on a 2A12 aluminum target at the same projectile incidence angles and difierent shock velocities, experimental measurements were conducted for light ∞ash phenomena of a 2A12 aluminum projectile impacting a 2A12 aluminum target under the conditions of difierent impact velocity and the same projectile incidence angles of 45 - by using an optical pyrometer measurement system and a two-stage light gas gun loading system. Experimental results show that the peak values of the light ∞ash radiant intensity for the wavelength of 550 nm are largest in the wavelength ranges of 600 nm, 650 nm and 700 nm when a 2A12 aluminum projectile impacts a double-layer 2A12 aluminum plate in the present experimental conditions.
