By infrared spectrum study , the limonite ( feooh nh2o ) can be considered the main colorating mineral in the yellow and red jadeite , and the hematite is another colorating mineral in the red jadeite . the difference of color tone is due to the n value in the molecular formula feooh nh2o and the content of crystal water and adsorbent water . the iron ion came from the effloresced and eroded rocks , and formed fe ( oh ) 3 colloid reacted with the surface water 周圍礦床的風化蝕變為表生水提供了鐵質,形成弱酸性的含fe ( oh ) _ 3膠體的水溶液,表生水流經翡翠礦石時, fe ( oh ) _ 3膠體附著在巖石的表面,經過脫水結晶和吸附,形成褐鐵礦膠體,褐鐵礦膠體沿裂隙或松散的礦物顆粒進入翡翠巖石中,逐漸累積沉淀,形成次生色層。
