Abstract

The Tertiary volcanic rocks in Mt. Avala occur as dykes intruded Jurassic serperitinite and sediments of diabase—chert formation and Neocomian flysch and sediments of the Turonian—Senonian flysch. Their thickness is range from 1 to 20 m, rarely to 100 m.

According mineral composition and whole rock chemistry volcanic rocks of Mt. Avala subdivided into two groups. The first group is characterize by the quartz — poor rocks of the basic — intemiediate character (basaltic trachyandesite, trachyandesite, latitic andesite, latite, andesite and kersantite). The second group composed of quartz—rich rocks of the intermediate — acidic character (quartz latite, dacitic andesite and dacite). 

The oldest are kersantite (54.58 Ma) and the jungest are quartz latite (25 to 23 Ma).
