Geologic vs. geographic constraints on cement resources

摘要: Abstract This study evaluates the importance of geologic and geographic factors in constraining location limestone mining operations for production cement Great Lakes region United States. Cities their infrastructure require abundant cement, which is manufactured from other quarry products, but expansion cities limits locations these operations. Possible are controlled by including distribution mineralogy formations as well depth overburden, wetlands, cities, surface features that preclude development quarries manufacturing Overlay analysis was used to evaluate factors. Results show that, although underlies about a third region, almost 50 percent this unavailable quarrying due coverage built environment, protected natural areas, or excessive overburden thickness. When characteristics such quality also accounted for, accessible resources shrink little 2 total land area. Although remaining area may supply local needs some years, clearly must be included long-term regional use planning.
