Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
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
Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

More about Wehrlite and Hyaloclastite
Here you can know more about Wehrlite and Hyaloclastite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Hyaloclastite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Hyaloclastite includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Hyaloclastite , the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Hyaloclastite is available in brown, grey, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Hyaloclastite is Dull. Properties of rock is another aspect for Wehrlite vs Hyaloclastite . The hardness of Wehrlite is 5.5-6 and that of Hyaloclastite is 1-2. The types of Wehrlite are Ultramafic 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 Wehrlite is white while that of Hyaloclastite is .
