Lode (Liepa) Clay Quarry is a Middle Devonian (Gauja suite, Lode Member) clay deposit located in the Liepa Parish territory (Cēsis Municipality). It is the biggest active clay quarry in Latvia. Almost all active clay quarries in the country consist of Quaternary Period rocks, only in the Lode quarry, Devonian clays are mined.
The Lode deposit was discovered in 1953 by the geologist J. Slienis. Ten years later industrial extraction of clay for brick-making was started. The clay-pit became world-famous in 1970 when Latvian geologist V.Kuršs discovered well-preserved fossils of Upper Devonian armoured fish and Strunius kurshi fish for the first time in history. Nowhere else fish fossils in such good condition have been discovered; part of the fossils can be viewed in the Latvian Museum of Natural History. The Lode armoured fish deposit, which is located in the southern part of the quarry is a protected natural monument. Some clay layers of the Gauja suite with rich fossil content are a geological object of world importance.
Nowadays clay is extracted by the company „Lode“ which produces finishing, oven-chimney, and construction bricks, as well as other clay items.
Clay fractions in the quarry rocks mainly consist of illite 80-85% and kaolinite 15-20%. Minor aleurite and sand fractions contain quartz, feldspar, mica (mainly muscovite) and carbonates (dolomite, calcite).
