In the study of infrared radiation character, different species of tourmaline and Draviteoccurring in pegmatites from Hebei that are different in granularity and heattreatmenttemperature are chose for infrared radiation ratio testing. The result shows:The infraredradiation ratio of tourmaline powder is above 0.80 when the surrounding temperature is 20℃and the testing temperature is below 100℃;Schorl has a close infrared radiation ratio to Dravite,which is higher than Elbaite;No matter to Dravite or Schorl, as the content of ferric oxideincreases, the infrared radiation ratio decreases;tourmaline's size is smaller, its infraredradiation ratio is higher;after tourmaline is heat-treated under 800℃, its infrared radiation ratiodeclines;Dravite heat-treated at 800℃ has the highest infrared radiation ratio, 0.90;andDravite's structure suffers from destruction above 900℃ heattreatment, so its infrared radiationratio goes down.

在红外辐射特性的研究中，本文选择了不同种属电气石、不同粒度和不同热处理温度河北伟晶岩镁电气石进行红外发射率的测试，结果表明：在环境温度为20℃、测试温度为100℃下，电气石粉体红外发射率均在0.80以上；铁、镁电气石红外发射率相近，且大于锂电气石；不论在铁电气石还是在镁电气石中，随氧化铁质量分数的增加，红外辐射率下降；电气石粒径越小，红外发射率越高；电气石在低于800℃以下温度的热处理后，红外发射率下降，800℃热处理电气石红外发射率最高，为0.90，900℃以上电气石结构遭到破坏，红外发射率降低。

Iron oxides would continue to be formed or at least not to be dissolved under oxic conditions, and the sediments in brown to red color will then be dominant. While in a reducing environment, iron oxides will be dissolved, with the possible migration of iron ion in the ocean, and then buried as siderite, pyrite, or other ironbearing minerals.

氧化强氧化条件利于沉积物中氧化铁的持续产生或者至少保持不被溶解的状态，从而形成棕色-红色沉积物；还原条件利于沉积物中铁氧化物的溶解，形成菱铁矿、黄铁矿等形式的埋藏，并可能造成溶解铁在海洋内的迁移。
