摘要: Magmatic differentiation in Pavagarh adopted the courses corresponding to olivine-basalt trend including olivine-basalt, mugearite, latite and pitch-stone normal basalt comprising tholeiitic basalts, andesite, dellenite, rhyolite. The dellenite-rhyolite assemblage is not consanguineous. Their average composition corresponds with petrochemical field of basalt-andesite-dacite-rhyolite association or calc-alkaline series Nockolds. It lies between plateau basalts different provinces shows alkali enrichment initial phases differentiation.
