长石类矿物是地壳中最常见的硅酸盐矿物,其风化作用对地球表面环境有显著影响,因而是风化作用研究的重点矿物之一。文中以长石为例,对硅酸盐矿物的风化作用研究现状从矿物的自然风化、模拟矿物化学风化和矿物的生物风化3个方面进行阐述; 对影响矿物风化的各种因素及其在风化过程中所起的作用,以及长石微生物风化作用的机理和过程进行分析; 指出目前硅酸盐矿物风化研究中存在的问题,并对未来的发展方向提出建议,指出对微生物-矿物复合体微环境物理化学性质的深入研究可能成为揭示微生物-矿物相互作用机理的一个突破口。 |

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. |
