Definition
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt

Archaeological Significance
Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
