Distribution of the Major and Trace Elements in the Volcanic Rocks of Yozgat Area, Turkey

Abstract

The investigation has been carried out the petrographycal and geochemical properties of the volcanic rocks in Yozgat area. These volcanic rocks are compared with some other volcanic formations and their origins are examined. The volcanic rock units of investigated area are pre-Lutetian diabases, amygdaloidal basalt intercalated with Lutetian sediments, tuff, agglomerates and post-Lutetian andesite-basalts. These volcanic rocks of the region present an affinity to the calc-alkaline suites of the island-arcs.
