Domeenitasolla

Domeenitasolla is a geological formation located in the southwestern part of Finland, in the Kangasala municipality of the Pirkanmaa region. It is a rare and unique example of a dolerite intrusion, a type of igneous rocks that have formed as a result of magma rising to the surface from beneath the Earth's crust.

The name "domeenitasolla" translates to "domain rock" in Finnish, referring to the fact that this formation represents a distinct geological domain within the region. The formation consists of a dome-shaped body of dolerite that has intruded into the surrounding bedrock, creating a distinctive landscape feature.

The geology of the domeenitasolla is characterized by a thick, dark-colored dolerite body that has intruded into the surrounding Paleoproterozoic bedrock. The formation is composed of coarse-grained rock that is rich in minerals such as plagioclase and orthopyroxene. The domeenitasolla is significant not only for its geological interest but also for its historical importance. The rock has been quarried for centuries, and the extracted dolerite has been used as a raw material in various industrial applications.

Field studies of the domeenitasolla have provided valuable insights into the geological history of the region. The formation is thought to have formed as a result of tectonic activity in the region, involving the movement of crustal plates and the rise of magma to the surface. Today, the domeenitasolla is recognized as an important geological feature and a significant part of Finland's natural heritage.
