Sediments and sedimentary minerals are products of weathering that involves the physical degradation and chemical alteration of rocks at the Earth’s surface. It is caused by chemical reactions involving air, water, salt, or acid, by freezing and thawing, and by plants and animals.Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. What is a concretion rock?

Thus, at the late stage of concretion development, the Mn supply is largely exhausted and their surface showed a higher Fe and lower Mn concentration (Timofeeva et al., 2014). Fig. 5 presents the schematic model of Fe-Mn concretions and nodules formation based on White and Dixon (1996) work.

The siderite concretion undergoes oxidative dissolution, which is possibly microbially mediated and which provides an internal source of Fe that forms an Fe-oxide crust on the outside the concretion. However, a problem with this model is that no siderite concretions have been identified, neither in outcrop ( 6 , 8 , 9 ) nor in any deeper ...
