La Baie de Somme est le plus important site mondial d'exploitation de galets avec plus de 280 000 tonnes/an de galets exploités sur quatres sites industriels. Les galets ne sont pas seulement concassés en granulats ou broyés en sables, ils sont également calcinés pour être transformés en silice utilisée notamment pour le marquage des routes ou la fabrication des composants électroniques en silicium. Le gisement de galets bleus de la Baie de Somme est exceptionnel car les galets sont içi de la meilleure qualité au monde de par leur teneur en silice très élevée atteignant 99 % .
