Vein (geology) Wikipedia

2019-7-9 · In geology, a vein is a distinct sheetlike body of crystallized minerals within a rock. Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation. The hydraulic flow involved is usually due to hydrothermal circulation.[1] Veins are classically thought of as being the result of

Identifying Minerals | Geology Lumen Learning

Minerals that are the same color may have a different colored streak. Many minerals, such as the quartz in the Figure 3, do not have streak. To check streak, scrape the mineral across an unglazed porcelain plate (Figure 5). Yellow-gold pyrite has a blackish streak, another indicator that pyrite is not gold, which has a golden yellow streak.
