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

2011-2-11 · common. Quartz veins clearly cut muscovite alteration, but replacement of plagioclase by the latter is most intense adjacent to the veins. Vein quartz is strained, but less so than magmatic quartz. Accessory phases in the veins include haematite, which appears from textures to have formed contemporaneously with quartz, and later tourmaline,Permissive tracts USGS,Low-sulfide Au-quartz veins, Chugach type: AK Peninsula & Aleutians: AK-AP07: Low-sulfide Au-quartz veins, Chugach type: AK Peninsula & Aleutians: AK-AP08: Low-sulfide Au-quartz veins, Chugach type: AK Peninsula & Aleutian Is.
