Determine about the Secondary minerals

Secondary minerals are formed under conditions of temperature and pressure found at the  Earth's surface by the weathering of pre-existing minerals. In this process, involving water as a common participant, elements are released into solution. Some of these elements are leached out of the soil material and end up in ground water, streams and eventually, ocean while some of the released elements are adsorbed and retained on the surface of the fine soil particle and serve as a readily available source of plant nutrients. Other released elements recombine, along with water, to form secondary minerals.
