Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
