Figure 4.6.5 4.6. 5: Some minerals have different streaks than their visual color. Streak examines the color of a powdered mineral and can be seen when a mineral sample is scratched or scraped on an unglazed porcelain streak plate. A paper page in a field notebook may also be used for the streak of some minerals.The lead content of some natural rocks (e.g. galena) was assessed. The rocks were dissolved in nitric acid and the lead (II) solution was measured by direct potentiometry using TP and PT ionophore based membrane sensors. The obtained results by potentiometric sensors in Table 6, which have been showed aGalena: Metallic: Softer than glass: 3 perfect cleavages at 90 degrees, high density.

It is found associated with galena in most important lead-zinc deposits. The name sphalerite is derived from a Greek word meaning "treacherous," an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore).
