The bottom of Lake Chebarkul’ was investigated by ground penetrating radar at the fall site of a large fragment of the Chelyabinsk meteorite. Linear profiles and 3D reconstructions revealed an anomalous depression of the lake floor relief and the disturbance of the structure of the ice cover, which indicate the possible place of meteorite fragment occurrence. 相似文献

Numerical simulations of a weathering profile on granite containing 10–8 mol/L Sn (whose average content in the Earth’s crust is 0.00025%) by the SELECTOR program package indicate that cassiterite SnO2 solubility under both oxidizing and reducing conditions is no higher than 10–10 mol/L within the pH range of 3 to 11. The only ion occurring in equilibrium with cassiterite is the neutral Sn(OH)4(aq) 0 complex, which was detected in both oxidizing and reducing environments. 相似文献
