Stargach

Stargach (, ), also known as Sturgach or Stargač, is a border mountain, situated between south-western Bulgaria in the Blagoevgrad Province and northern Greece in the Drama region. It is a part of the Rhodope Mountains, sitting east of Slavyanka Mountain and south of the Pirin Mountains.

Stargach has an anticline structure going mostly in the north-south direction. Stargach is composed mostly of various metamorphic rocks–marble and gneiss, as well as feldspar, mica, and quartz minerals. Granitoids within the core of the anticline structure indicate an age for Stargach around the Paleozoic Era, coinciding with the Hercynian orogeny. Granite plutons are also present at Stargach and in the surrounding areas, dated to the Late Cretaceous period, as well as minerals associated with magmatic processes from the Tertiary period in the wider metallogenic zone across the eastern Balkans.
