"This publication is a conference report that highlights recent research on gossans as natural laboratories used in environmental geosciences and metallogeny. Gossans preserve anomalous concentrations of metals that are routinely investigated in the search for new ore bodies. Under certain conditions, gossans also constitute analogues of mine waste deposits. On a regional scale, the streams, lakes and permafrost that are affected by the specific mineralogy of gossans provide indicators of environmental impact. What is often overlooked in field investigations of gossans is the stratigraphic, mineralogical and geochemical complexity of these surficial deposits"--page 1.
