The present and past mining activity left several abandoned tailings and dams in the Panasqueira tin–tungsten mining area. Seasonal water samples and stream sediments were collected during two different periods (rainy and dry seasons) and analyzed for a wide range of major and trace elements, in order to define the present hydrochemical situation. Rain waters …

unpatented lode mining claims, covering 158.8 acres, on federal land managed by the U.S. Bureau of Land Management. The Paramount Mine was a high-grade silver, gold, lead, and zinc mine that was active from the 1870's to 1940's. The Old Para-mount Mine reported grades of 15 ounces silver per ton, .25 ounces gold per ton, and 40% lead.

Geochemical knowledge is vital to solving complex reclama-tion problems. They are equally abundant in fine-grained uncon-solidated sediments and are important constituents of soils. Quartz is the most important mineral in the coarser sediments and rocks, such as sand and sandstone, and is very common in nearly all other types of overburden rocks.
