Definition
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment
  
Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
  
The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.

Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Hyaloclastite vs Banded iron formation characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hyaloclastite and Properties of Banded iron formation. Learn more about Hyaloclastite vs Banded iron formation in the next section. The interior uses of Hyaloclastite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Banded iron formation include Decorative aggregates and Homes. Due to some exceptional properties of Hyaloclastite and Banded iron formation, they have various applications in construction industry. The uses of Hyaloclastite in construction industry include Building houses or walls, Construction aggregate and that of Banded iron formation include As dimension stone, Used for flooring, stair treads, borders and window sills..
More about Hyaloclastite and Banded iron formation
Here you can know more about Hyaloclastite and Banded iron formation. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Banded iron formation consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Hyaloclastite is Dull and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Hyaloclastite vs Banded iron formation. The hardness of Hyaloclastite is 1-2 and that of Banded iron formation is 5.5-6. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Hyaloclastite is colorless while that of Banded iron formation is white. The specific heat capacity of Hyaloclastite is Not Available and that of Banded iron formation is 3.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Hyaloclastite is heat resistant whereas Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
