在矿物学的变化，微生物群落结构和水生生物地球化学的细菌成因的铁氧化物（BIOS）沉积在环中性地下水渗漏的季节性记录。X射线衍射和X射线吸收光谱表明，2线的水铁矿占主导地位的BIOS的含铁矿物（>60%）。在全年收集的BIOS中也检测到少量更多结晶的纤铁矿（
Changes in the mineralogy, microbial community structure and aquatic geochemistry of bacteriogenic iron oxides (BIOS) deposited at a circumneutral groundwater seep were recorded seasonally. Xray diffraction and X-ray absorption spectroscopy demonstrated that 2-line ferrihydrite dominated the iron-bearing mineralogy of the BIOS (>60%). Minor proportions of the more crystalline lepidocrocite were also detected in BIOS collected throughout the year (
