Antioquia batholith
Quick Summary
A batholith is a large body of igneous rock formed beneath the Earth's surface from solidified magma. Typically composed of coarse-grained rocks like granite, batholiths cover at least 100 square kilometers and have irregular shapes with steeply inclined side walls against the surrounding rock. They are often elongated along mountain ranges and can cause metamorphism in the adjacent rock.1
In Colombia, the Antioquia batholith is an exposed granitic intrusion located in the central part of the country. This tableland averages about 8,000 feet above sea level and is divided by the Porce River. Historically, the Antioquia batholith contained gold-bearing quartz veins that were a significant source for mining.2
