Zhang Heng Mine is a natural mineral found in Meixian meteorite in Anhui Province. Its symbiotic minerals are olivine, clinopyroxene, orthopyroxene, plagioclase, orthoclase, scheelite, quartz, biotite, dolomite, calcite, corundum, pyrite, ferrite, nickel Serpentine, chromite, ilmenite, magnesia spinel, pentlandite, graphite, wartime, natural copper, such as magnetite. Minerals are golden yellow, streaks of copper yellow. Opaque with metallic sheen. Crystal granular, irregular granular, plate-like, dendritic, particle size of 0.13 × 0.15-0.1 × 0.35mm ~ 2. H _? = 145-150kg / mm ~ 2. No understanding. Density (calculated) = 8.32 g / cm ~ 3. Reflective light yellow, homogeneous. Electron probe analysis results; Cu52.77, Zn46.78, Fe0.12, Al0.05, Cr0.25, Ni0.01, the sum of 99.98wt%. The ideal chemical formula is CuZn. By X-ray powder analysis identified as equiaxed crystal system, heart and heart lattice, disordered structure, the space group Im3m, a = 2.952 (2) A. The unit cell volume V = 25.72A ~ 3, Z = 1.
