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
Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Hyaloclastite vs Lignite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Hyaloclastite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hyaloclastite and Properties of Lignite. Learn more about Hyaloclastite vs Lignite in the next section. The interior uses of Hyaloclastite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Hyaloclastite and Lignite, they have various applications in construction industry. The uses of Hyaloclastite in construction industry include Building houses or walls, Construction aggregate and that of Lignite include For road aggregate, Steel production.
More about Hyaloclastite and Lignite
Here you can know more about Hyaloclastite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hyaloclastite and Lignite consists of mineral content and compound content. The mineral content of Hyaloclastite includes Calcite, Chlorite and mineral content of Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Hyaloclastite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Hyaloclastite is available in brown, grey, yellow colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Hyaloclastite is Dull and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Hyaloclastite vs Lignite. The hardness of Hyaloclastite is 1-2 and that of Lignite is 1. The types of Hyaloclastite are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff and Andesitic tuff. whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. 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 Lignite is black. The specific heat capacity of Hyaloclastite is Not Available and that of Lignite is 1.26 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 Lignite is heat resistant.
