Note: Since December 2014, the quarry of Hourt, digging the oldest Belgian rock, the quartzite of the Deville Formation, and hosting some mineralized quartz veins, has resumed activity.

However, after only a few months of work, too many problems were met (e.g. stones thrown through all windows of the quarry office, fuel thefts and misuse of equipment, and mainly trespassers, looking for minerals, but found in dangerous positions on the quarry walls).

Access to the premises is now (April 2015) no longer allowed to visitors and mineral collectors by the management (at all times as posted on the fences).

NB: The quarry is identified by the owner as the "Carrière Grand Halleux" (Oct. 2016, Joan Rosell).

Detailed Mineral List:

Anatase
Formula: TiO2
Arseniosiderite
Formula: Ca2Fe3+3(AsO4)3O2 · 3H2O
Arsenoflorencite-(Ce)
Formula: CeAl3(AsO4)2(OH)6
Arsenopyrite
Formula: FeAsS
Habit: Lefevre & Hatert (2003): "Goniometric measurements have shown the presence of the forms {100} and {001}. In general, the crystals also show alternating striations with the axis [101], among which the facets {λ21} and {λ41} have been recognised. Other less frequently occurring crystals present a simpler morphology characterised by the combination {100} {001} {λ31}, with smaller less developed facets {λ01} and {λ11} . Besides the twin (111) in the shape of a St Andrew's cross, the twin (100) has also been observed at the site."
Description: Crystals up to 3mm long disseminated in quartzite.
References:
Bariopharmacosiderite
Formula: Ba0.5Fe3+4(AsO4)3(OH)4 · 5H2O
Description: Lefevre & Hatert (2003): "Other crystals [of pharmacosiderite] have been identified on the graulichite-(Ce) aggregates. Qualitative chemical analysis of these crystals has shown an enrichment in Ba compared to K, indicating that they would probably consist of bariopharmacosiderite." Hatert et al. (2003): "It is noteworthy that Lefèvre (2001) described barium-pharmacosiderite, BaFe3+8(AsO4)6(OH)8.14H2O, in very close association with the new mineral species [graulichite-(Ce)]."
