Mugearite and Claystone
Definition
Definition
Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Formation
Formation
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
