Smilšu karjeri: kas tie ir un kur tos var atrast

Smilšu karjers ir smilšu ieplaka, kas rodas zemes rakšanas vai ieguves rezultātā. Karjeri parasti tiek izveidoti cieto minerālu, piemēram, akmeņu, atradņu laikā, marmors, māls, grants, un tiek iegūti smilšakmeņi.

Karjers ir sava veida atklāta bedre mans, jo tas ir atvērts Zemes virsmai. Tās bieži var būt vairākas jūdzes dziļas.

Sand quarries are typically located near sources of sand, such as on the shores of rivers, ezeri, or oceans, or in desert regions where sand dunes are found.

Agregāts ir tas, kas tiek iegūts no karjera smilšu izteiksmē, grants, vai šķembas. Betons un asfalts ir izgatavoti no minerālmateriāla, ko izmanto arī būvniecībā, lai izveidotu izturīgus pamatus tādām lietām kā lielceļi un vilcienu sliežu ceļi.
