The concept of conflict diamonds or "blood diamonds" emerged in the late 1990s when it became evident that several violent civil wars in Africa were connected to mining and trading of rough diamonds. In 2006, the U.S. Geological Survey was asked by the U.S. Department of State to help address illegal diamond mining in Africa.

According to the label assigned from the NLCD to each change polygon, mining is the predominant land use/land cover represented in the topographic change inventory. This is not surprising, as surface mining operations have been previously identified in the literature as the largest direct anthropogenic process in terms of the amount of material moved.

In 2012, estimated world lithium consumption was about 28 kt (31,000 st) of lithium contained in minerals and compounds, an 8 percent increase from that of 2011. Estimated U.S. consumption was about 2 kt (2,200 st) of contained lithium, the same as that of 2011. The United States was thought to rank fourth in consumption of lithium and remained the leading importer …

To understand the contamination caused by historic mining in California, researchers sampled sediment, water, and biota (animals) during the years 1999–2004 and 2011–2012. From the data collected, a set of interactive maps were produced. The maps, along with the data release and introductory video, explain the results of the research.

The scientific legacy of the USGS is the data and the scientific knowledge derived from it gathered over 130 years of research. However, it is widely assumed, and in some cases known, that high quality data, particularly legacy data critical for large time-scale analyses such as climate change and habitat change, is hidden away in case files, file cabinets, and hard drives …
