Definition
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Etymology
From German Troklotit, from Greek trōktēs, a marine fish (taken to be trout)
From English clay and stone as the rock contains more amount of clay

Formation
Troctolite 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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

More about Troctolite and Claystone
Here you can know more about Troctolite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Troctolite and Claystone consists of mineral content and compound content. The mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Troctolite vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Troctolite is available in dark grey to black colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Troctolite is Veined and Shiny and that of Claystone is Rough and Dull. Properties of rock is another aspect for Troctolite vs Claystone. The hardness of Troctolite is 7 and that of Claystone is 3.5-4. The types of Troctolite are Not Available whereas types of Claystone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Troctolite is black while that of Claystone is white. The specific heat capacity of Troctolite is Not Available and that of Claystone is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Troctolite is impact resistant, pressure resistant, wear resistant whereas Claystone is heat resistant, impact resistant.
