Sparagmite

Sparagmite (from the Latin sparagma, meaning "fragment") is an arkosic sandstone, greywacke and conglomerate set of beds so named by Jens Esmark in 1829.[1] Deposited in what is now Scandinavia during the Neoproterozoic Era to early Cambrian time,[2] the sparagmite nappes were transported up to several hundred kilometers during the Caledonian collision. Sparagmite is characterized by high feldspar percentages of microcline.[3]
