However, ultra structural features ( spiral defects) discovered in some of the ALH84001 magnetites suggest that they were formed by vapour deposition at high temperatures. 然而,在84001上发现的一些极端结构也可以经高温气象淀积法形成。
In addition, the ALH84001 magnetites exhibit epitaxial growth relationships with the host carbonate, and are therefore unlikely to have formed within the cells of bacteria ( Bradley et al. 1998). 此外,84001磁铁矿显示的外延生长特点与大量碳酸盐有关,因此,与细菌细胞内部形成的也可能有所不同。
The Dynamic Behavior of Magnetites and Granite under High Strain Rates 高应变率下的岩石动载特性
The ore minerals ( magnetites), vein minerals ( loivines), and ore district volcanics own similar REE partition pattern of heavy REE concentration type. 矿石中矿石矿物磁铁矿与脉石矿物石榴石和矿区火山岩的稀土元素配分型式相似,均属重稀土富集型。
A study on process mineralogy of vanadium-bearing titaniferous magnetites 钒钛磁铁矿的工艺矿物学研究
Diagenetic magnetites within sedimentary cover strata over oil or gas field are present primarily as spherical crystal aggregates that usually carry stable chemical remanent magnetization ( CRM). 含油气区沉积盖层中分布的成岩磁铁矿具有典型球粒状的特有矿物形貌标志,它们携带了较为稳定的化学剩磁(CRM)。
This paper describes the results of the small-scale test on sodium sulphate roasting and oxidizing roasting of the Concentrate pellets of vanadium-bearing titaniferous magnetites from Chengde Iron and Steel company and the results of the pilot-plant test carried out in the rotary kiln-leaching pot system. 本文介绍了钠化氧化焙烧承钢铁钒精矿球团&水漫提钒小型试验研究结果以及在回转窑-浸出罐系统进行的扩大试验结果。
From the peak area method of Mossbauer spectrum, we have deduced the non-stoichiometric crystal structure formulae of magnetites, and subsequently we have calculated the ratio Fe2+/ Fe3+. 从穆斯堡尔谱峰面积法,推算出非正分的磁铁矿晶体结构式,并由此算出其中Fe~(2+)和Fe~(3+)的含量比。
Ti and V are concentrated in magnetites from the Fujiang River and Hanjiang River, and Ti and Al are rich in the Xiangjiang River. 涪江、汉江磁铁矿富Ti和V,而湘江磁铁矿富Ti和Al;
