Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

More about Sandstone and Flint
Here you can know more about Sandstone and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Sandstone and Flint consists of mineral content and compound content. The mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Flint includes Silicon. You can also check out the list of all Sedimentary Rocks. When we have to compare Sandstone vs Flint, the texture, color and appearance plays an important role in determining the type of rock. Sandstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Flint is available in black, brown, green, grey, red, white colors. Appearance of Sandstone is Rough and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Sandstone vs Flint. The hardness of Sandstone is 6-7 and that of Flint is 7. The types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister whereas types of Flint are Chert and Jasper. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Sandstone and Flint is white. The specific heat capacity of Sandstone is 0.92 kJ/Kg K and that of Flint is 0.74 kJ/Kg K.
