Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
Siltstone can be defined as a fine-grained sedimentary rock which mainly consists of consolidated silt

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

More about Hawaiite and Siltstone
Here you can know more about Hawaiite and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Siltstone consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Hawaiite vs Siltstone, the texture, color and appearance plays an important role in determining the type of rock. Hawaiite is available in black, brown, light to dark grey colors whereas, Siltstone is available in brown, red, reddish brown colors. Appearance of Hawaiite is Dull and Soft and that of Siltstone is Rough. Properties of rock is another aspect for Hawaiite vs Siltstone. The hardness of Hawaiite is 6 and that of Siltstone is 6-7.
