Valkenburg aan de Geul (Dutch: [ˈvɑlkə(m)bʏr(ə)x aːn də ˈɣøːl]; Limburgish: Valkeberg [ˈvɑl˦əkəˌbæʀ˦əç]) is a municipality situated in the southeastern Dutch province of Limburg. The name refers to the central town in the municipality, Valkenburg, and the small river Geul passing through it.

Flint mining took place in the Valkenburg area between ca. 3100 and ca. 2900 B.C.

Breuls (1994): "If we [also] take into account the small quarries, there are nearly 250 [marl and flint] quarries in the region between Tongeren in Belgium [https://www.mindat.org/loc-288530.html] and Valkenburg aan de Geul in the Netherlands."

Geochronology

Mineralization age: Late/Upper Cretaceous : 100.5 Ma to 66.0 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
