Lávový suk Červená hora, Volcanic formation in Norberčany, Czech Republic

The Červená hora lava plug is a basalt outcrop in the middle of a former quarry west of Červená hora (749 m) in the Nízký Jeseník range, Norberčany cadastre. Quarry walls around the plug rise to about 20 m and are partly formed of clayey shales baked red-brown by contact metamorphism with the magma, up to roughly 15 m from the contact. The basalt shows spherical jointing, and dark green olivine can be found.

Červená hora was an active stratovolcano during Cenozoic volcanism; erosion later exposed the solidified feeder conduit, lava flow and pyroclastic sediment as a denudation relic. Basalt was quarried here in a now-abandoned pit west of the 749 m summit, in the Nízký Jeseník range near Norberčany.

The name Červená hora, "Red Mountain", comes from the red-brown colour of the clayey shales around the basalt plug, baked by escaping magma into porcelanite up to about 15 metres from the contact. Visitors can see this scorched rock in the quarry walls, which rise some 20 metres around the plug.

The lava plug lies in the middle of a former basalt quarry west of the Červená hora summit, in the Norberčany cadastre. Quarry walls around the plug reach about 20 metres and expose clayey shales baked red-brown by the magma. The site is reached on foot; the nearby summit carries a meteorological station, a former navigation tower and a transmitter.

The quarry walls around the basalt plug, up to about 20 metres high, are clayey shales baked by escaping magma into reddish-brown porcelanite within roughly 15 metres of the contact. Dark green olivine crystals are found in the basalt, which breaks into rounded, ball-like forms.
