Definition
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

More about Ganister and Hyaloclastite
Here you can know more about Ganister and Hyaloclastite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ganister and Hyaloclastite consists of mineral content and compound content. The mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Hyaloclastite includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Ganister vs Hyaloclastite , the texture, color and appearance plays an important role in determining the type of rock. Ganister is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Hyaloclastite is available in brown, grey, yellow colors. Appearance of Ganister is Rough and that of Hyaloclastite is Dull. Properties of rock is another aspect for Ganister vs Hyaloclastite . The hardness of Ganister is 6-7 and that of Hyaloclastite is 1-2. The types of Ganister are Siliceous rock whereas types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ganister is white while that of Hyaloclastite is .
