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鬆散的礦物顆粒進入翡翠巖石中,逐漸累積沉澱,形成次生色層。Wind-deposited sediment called loess occurs in many places.
被稱為黃土的風成沉積物,在許多地區均有。The research indicates that the climate character which is the temporal coupling of aridity, lack of rain and excessive wind, together with the thick sand matter sediment of the west liao river system, lead to the frangibility of environment in keerqin sandlot. in the recent years, there is a seriously lack of water resources. about 50 p
研究表明:該地區氣候特徵表現為乾旱、少雨、多風在時間上的耦合,加之西遼河水系巨厚的沙物質沉積,構成了科爾沁沙地生態環境的脆弱性』 o近些年來,水資源嚴重短缺,由於降水減少和不斷採集地下水,近50的湖、泡己乾涸。( 4 ) we defined ssee factor ( surficial soil element enrichment factor ) and wpem factor ( weathering profile element mobility factor ), and applied them to evaluate the degree of effects of black shales weathering on soil, water bodies and their sediments composition
( 4 )提出了表土層元素富集因子和風化剖面元素遷出因子,用於估算巖石風化對水體及其沉積物、土壤的化學組成影響的程度。It is thought that the holocene original sediments were the result of the aeolation in the area, but the stream action influence the formation of deuterogenic loess
認為本地區全新世原始沉積物是風成的,但流水作用影響了次生黃土的形成。( 2 ) there is stage of soil formation from the evolution of pedogenic environment in the weihe valley during holocene. soil formation shows the law of evolving from warm and wet strong soil formation period to cold and dry dust deposition period ( weak soil formation period ) and to warm and wet strong soil formation period again. the loess - soil sequence is a compound soil sectional system of different kinds of soil evolution under different bio - environment and pedogenic processes
( 2 )通過對全新世渭河流域成壤環境演變問題的討論,揭示了全新世渭河流域土壤的發育具有階段性,表現為由溫濕的強成壤期向冷乾的沉積期(弱成壤期)演變、再向溫濕的強成壤期演變的規律;黃土一古土壤序列是不同生物氣候環境下、不同成壤過程發育的不同土壤類型演替而形成的復合型土壤剖面體系;而且由於冬夏季風環流及其環境效應在空間上的差異,使得復合型土壤剖面體系也存在著南北差異。So, the ash content in peat sediment can be used as a proxy to indicate the winter monsoon intensity, higher ash content shows stronger winter monsoon, and the vice versa
