Vein (geology) Wikipedia

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. Gold bearing quartz veins, Blue Ribbon Mine, Alaska. For this reason, veins within hydrothermal gold deposits are no longer the

Microtextures and fluid inclusions from vein minerals

The proportion between quartz and calcite varies from pure quartz to calcite-dominated veins. Additionally, quartz crystals are located between grain boundaries of late-stage calcite. Late-stage calcite shows type I and II twinning ( Burkhard, 1993 ), and quartz exhibits undulatory extinction.
