Wienerberger clay pits

Rumst is a town in the province of Antwerpen, Belgium, nestled in the Flemish region, approximately 15 km south of the bustling port city of Antwerpen. This location places it in northern Belgium, accessible via the A1/E19 highway, with nearby regional airports in Antwerpen and Brussels. The Wienerberger clay pits, specifically in Reet, are part of this area, known for its rich clay deposits along the riverbanks, historically significant for brick production.

The clay pits are primarily composed of clay minerals, including illite, smectite, kaolinite, and chlorite, which are crucial for brick manufacturing. Of particular interest are the septarian nodules, locally called "kleibrood" or "clay bread," which contain pyrite and calcite, with the calcite exhibiting fluorescence under certain conditions. These nodules offer a unique glimpse into the mineral diversity, appealing to enthusiasts seeking uncommon specimens.

The geological context is the Boom Clay formation, a sedimentary rock from the Oligocene epoch, known for its clay-rich composition. This formation supports the area's brick industry, with the clay minerals resulting from weathering and deposition processes. The septarian nodules, formed through diagenesis, add an intriguing layer, containing minerals like calcite and pyrite, enhancing the locality's geological appeal.

Brick manufacturing in Rumst has roots in the 19th century, driven by the region's clay resources. Wienerberger Bricks currently operates the pits, continuing a tradition that saw significant mechanization and industry consolidation over time. The ongoing operations reflect the area's enduring connection to clay product production, with historical shifts from manual to modern methods shaping its economic landscape.

Rumst's identity is deeply tied to its brick-making heritage, a legacy that has shaped its landscape and community. Notable figures like Yvonne Verbeeck, a singer and actress, hail from here, adding cultural depth. The town also hosts the camping area for the Tomorrowland festival, blending modern cultural events with its industrial past, and offering a vibrant contrast to its historical roots.

Rumst experiences a temperate maritime climate, with mild winters and cool summers, typical of northern Belgium. The area's ecology is diverse, featuring riverine environments and clay pits that support various flora and fauna. Conservation efforts focus on preserving rare species, reflecting the region's commitment to balancing industrial activity with environmental stewardship.
