Formation
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.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

More about Siltstone and Oolite
Here you can know more about Siltstone and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Siltstone and Oolite consists of mineral content and compound content. The mineral content of Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Siltstone vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Siltstone is available in brown, red, reddish brown colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Siltstone is Rough and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Siltstone vs Oolite. The hardness of Siltstone is 6-7 and that of Oolite is 3-4. The types of Siltstone are Not Available whereas types of Oolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Siltstone and Oolite is white. The specific heat capacity of Siltstone is Not Available and that of Oolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Siltstone is heat resistant, impact resistant, pressure resistant, water resistant whereas Oolite is heat resistant, wear resistant.
