摘要

Since meromixis was first described by FINDENEGG (1932), sev-eral natural meromictic lakes have been described (HONGVE 2002, HAKALA et al. 2004). Meromixis can also be a common feature in mining lakes. A certain morphometry (high depth, small surface area) and the inflow of highly mineralised groundwater promote the formation 'of permanent density stratification. A well-known example for artificial meromixis is the Island Copper Mine (Vancouver Island, BC/Canada; FISHER & LAWRENCE 2000). In the Lusatian mining district, where lignite mining has lasted for more than 200 years, sev-eral meromictic mining lakes are known. Some have shown a permanent density stratification, such as Lake Lugteich (Nlx-DORF et al. 2001); others for a certain period, such as Lake Plessa 111 (KARAKAS et al. 2003). The meromixis of the Lusa-tian mining lakes originates mainly from internal geochemical and biological reactions with the transformation of iron as the predominant process (BOEHRER & SCHULTZE 2005).We studied the influence of groundwater inflow and inter-nal geochemical processes.that contribute to the development of meromixis in a small meromictic lake of the Lusatian min-ing district.
