Definition
Diatomite is a fine-grained sedimentary rock which is formed from consolidated diatomaceous earth
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

Archaeological Significance
Formation
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

More about Diatomite and Hyaloclastite
Here you can know more about Diatomite and Hyaloclastite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Hyaloclastite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Hyaloclastite includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Diatomite vs Hyaloclastite , the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Hyaloclastite is available in brown, grey, yellow colors. Appearance of Diatomite is Soft and that of Hyaloclastite is Dull. Properties of rock is another aspect for Diatomite vs Hyaloclastite . The hardness of Diatomite is 1 and that of Hyaloclastite is 1-2. The types of Diatomite are Diatomite 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 Diatomite is white while that of Hyaloclastite is . The specific heat capacity of Diatomite is 0.90 kJ/Kg K and that of Hyaloclastite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diatomite is heat resistant whereas Hyaloclastite is heat resistant.
