Location description

In eastern part of The Netherlands several sandquarries are located. The quarries are located in Sibculo, Westerhaar(sandquarry Alderink), Bruinehaar, Kloosterhaar (sandquarries Anker and Sierink) and Balderhaar (sandquarries Megamix and Oude Nijweme.

The sand are from the Enschede formation Enschede (Pleistocene; part of the Neogene period). This is a river sediment from rivers flowing west from the Baltic area. The pebbles originate from several sediments in the Baltic area. Famous are the sponges from the Ordovician period.

In the sandquarries the sand is sieved and sorted. The rocks and pebbles are on separate heaps. Beware of falling rocks!
