At longer extraction times (180 min), slopes and intercepts of the linear regression lines (Figure 1 , inset) tend to be smaller, which results in less depleted isotopic signatures of ...

2021-6-12 Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.

Read MoreOffshore sand and gravel extraction involves the abstraction of sediments from a bed which is always covered with seawater. This activity started in the early 20th century (in the mid-1920s, in the United Kingdom), but did not reach a significant scale until the 1960s and 1970s, when markets for marine sand and gravel expanded and dredging technology improved (Fig. 1).
