Late-stage anhedral calcite and accessorily goethite precipitated in non-sealed vein sites . 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.VOLCANIC-ASSOCIATED MASSIVE SULFIDE DEPOSITS ,2004-2-18 · deposits can be divided into three general categories. Cyprus-type deposits (Model 24a; Singer, 1986a) tend to be small, medium-grade deposits rich in copper and zinc. They are generally lens or mound shaped accumulations of massive pyrite developed in ophiolite-related, extrusive basalt sequences. They are typically underlain by copper-rich
