Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

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