2.1. Microorganism. A 50 × 50 cm 2 square-corer core was obtained from the South China Sea (5°36.51′ N, 113°38.97′; depth: 2125 m). The sampled sediment surface temperature was 9 °C, the pH was 7.4, and the Eh was 201. All the cores were opened from the side onboard, and sub-samples were collected from the center of the core under …
Ferromanganese & Ferrochrome | Some Meteorite …
A type of meteorwrong that we have encountered ~15 times (persons have sent samples or photos) is an industrial alloy called ferromanganese that is used in making steel. Ferromanganese is characterized by: High density, 7.2-7.4 g/cm 3, which is perhaps the first characteristic that people notice. 75-85% manganese (Mn), 6-7% carbon (C), with …
