Sand and gravel resources can be mined from a variety of depositional settings such as floodplains, alluvial fans, shorelines, and sand dunes, although river channels and glacial deposits are the most important (Yeend, 1973; Sutphin et al., 2002; Walther, 2014). These deposits can be modern (active) or preserved in the stratigraphy.
Besides cement, natural sand and gravel are the principal con-stituents of concrete, while hard-rock aggregates and to a certain extent crushed gravel is used mainly for pavement. For instance, asphalt pavements consist of 90–95% aggregates, whereas the rest is bitumen and filler. The mechanical and physical properties of the aggregates de-

Factors in Calculating Mineral Rights Value The reason it is impossible to accurately calculate mineral rights value is because there are many factors that play a role in the value. No two mineral rights properties are ever identical. This is why it's impossible to find an average price per acre for mineral rights. The only
Mining, the Environment, and Politics; A mineral deposit is a place in Earth's crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse is not true. Many factors control …
