摘要
安徽定远北部山区方解石矿与该区地质构造，特别是节理的发肓密切相关。区内节理经历了剪切追踪晚期改造的发育过程。主要的三套节理分别受不同时期的主应力场所制约。整个控矿带节理的发育经历了裂开愈合的发肓过程。其中第二期（由郯庐断裂系左行平移而诱导所致）应力场叠加作用下形成的追踪张裂，为结晶物质充填成矿提供了有利空间。
Besides its margin where ten saline ponds and ephemeral ponds rest, the Chaerhan salt lake as a whole is covered by salt incrustings typed as 1 polygonal, 2 cuspidate, 3 bumpy and 4 flat. These salt surfaces are growing outwards from the centres of the ponds, creating a number of old to young rings or semirings, an inherent geomorphology to the Chaerhan.
