Thermal models show that even if the asteroids assembled immediately after the formation of the chondrules, 26al heating would have raised temperatures in the interiors of ordinary - chondrite bodies to a maximum of 1, 100 degrees c ? high enough to cause melting of metals and sulfides but too low to melt silicate minerals extensively and differentiate an asteroid
熱模型顯示,即使小行星在球粒形成之後立刻聚合,鋁26的加熱最多也只能將普通球粒隕石內的溫度提高到1100 ,雖可使金屬和硫化物熔化,但並不足以將矽酸鹽礦物大量熔化並造成小行星各層分異。Fanned by a constant updraught of ventilation between the kitchen and the chimneyflue, ignition was communicated from the faggots of precombustible fuel to polyhedral masses of bituminous coal, containing in compressed mineral form the foliated fossilised decidua of primeval forests which had in turn derived their vegetative existence from the sun, primal source of heat radiant, transmitted through omnipresent luminiferous diathermanous ether

通過野外考察顯微鏡下薄片鑒定x射線物相分析和礦物紅外光譜等研究,確定了阿希金礦濁沸石化的普遍存在根據濁沸石化發生的規律及其與礦床形成的關系,確定濁沸石化主要見于礦體的上部和外圍,發育在地熱流體系統的邊緣和演化晚期,可作為尋找淺成低溫熱液型金礦的標志之一。導致阿希金礦濁沸石化的流體性質與熱泉型金礦成礦流體和現代地熱田類似,流體作用發生在石炭紀,證明西天山地區具有良好的淺成低溫熱液型金礦的形成和保存環境,因此找礦前景較好。In charge of one of major subjects of the national eighth five - year plan, i. e.
