一、沉积矿床中铁的活化和搬运形式 典型的沉积铁矿石的形成与铁从大陆带入沉积盆地有关。地下径流对陆源物质的活化起着巨大的作用。根据φ.A.马卡连科的意见,现代大多数平原地区的河流主要依靠地下径流的上带潜水来补给,因此大量的铁通过此途径经常不断地进入河流中。在某些情况下,出露地表的地下水中铁的浓度仍 1. Activation and Handling of Iron in Sedimentary Deposits The formation of typical sedimentary iron ore is associated with the migration of iron into the sedimentary basin from the mainland. Underground runoff plays a huge role in the activation of terrigenous materials. According to Makarinko, in most modern plains the rivers in the plains relied mainly on the submerged run-on scuba diversions, so much of the iron was constantly entering the river through this route. In some cases, the concentration of iron in the groundwater that is exposed to the surface remains
