Abstract:

Feldspar is one of the most common silicate minerals, and the weathering processes of feldspar have significant influences on the earth surface environments，thus feldspar becomes one of the significant silicate minerals in weathering researches. In this paper, exemplified by feldspar, the weathering processes of silicate minerals were summarized on the aspects of natural weathering, simulated chemical weathering, and biological weathering. The roles of various impact factors on mineral weathering, and the processes and mechanisms of feldspar weathering were analyzed. Several suggestions were proposed for current existing problems and future exploration, and the study on microenvironmental physicochemical properties of microbeminerals aggregates is likely to be the breakthrough point in the field of silicate minerals weathering research.

Key words: silicate minerals, feldspar, weathering, research progress, mechanism
