Recent development in bio-weathering research

Although organisms always participate in the weathering of mineral and rock on the earth surface,much attention was paid to the physical and chemical processes,but little attention to the biological process in previous studies of weathering.Recent studies indicated that all organisms,e.g.,animal,plant,and microbe,might take part in the bio-weathering process.Therefore,studies on the mechanism of bio-weathering and the corresponding evolution sequence of mineral will help us in understanding the formation of soil,the environmental cycle of elements,and the global environmental changes.
