Appinite and Claystone
Definition
Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Etymology
From the variety of Lamprophyre Greek lampros bright and shining + porphureos purple
From English clay and stone as the rock contains more amount of clay

Formation
Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
