Definition
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

Formation
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.

More about Travertine and Slate
Here you can know more about Travertine and Slate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Slate consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Slate includes Apatite, Biotite, Chlorite, Feldspar, Graphite, Hematite, Kaolinite, Magnetite, Pyrite, Tourmaline, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Slate, the texture, color and appearance plays an important role in determining the type of rock. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas, Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors. Appearance of Travertine is Fibrous and that of Slate is Dull. Properties of rock is another aspect for Travertine vs Slate. Hardness of Travertine and Slate is 3-4. The types of Travertine are Not Available whereas types of Slate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine is white while that of Slate is light to dark brown. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Slate is 0.76 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Travertine is impact resistant, pressure resistant, wear resistant whereas Slate is heat resistant, impact resistant, pressure resistant, wear resistant.
