The study on magnetizing reduction thermodymatics of high intensity magnetic separation concentrates of Daye Mine proved: because of there are high siderite in this type iron ore, CO and CO2 emitting out after siderite decomposing influenced on magnetic reaction heavily.

大冶铁矿尾矿难选红铁矿磁化焙烧热力学分析表明，因为该类矿石菱铁矿含量高，分解后产生CO和CO2对磁化焙烧反应影响较大，在CO含量大于1%的情况下，磁化焙烧即能完成。

The feature of oxygen isotope for magnetite from Abagong iron deposit reflects that the water in the fluid of mineralization resides in the initial magma, implying the magma genesis of mineralization. The similaritary features of REE and trace elements for coexisting apatite with magnetite in the Abagong, the Kiruna type and the Ninwu porphyrite iron deposit show their common genesis, indicating that Abagong iron deposit resulted from the intrusion of late ore magma due to the magma differentiation. The characteristic of sulfur isotope composition implies that the Abagong iron deposit resides in basaltic magma from mantle resource.

阿巴宫铁矿磁铁矿氧同位素特征反映了成矿流体中水来源于原始岩浆水，暗示该铁矿的岩浆成因；与磁铁矿共生的磷灰石稀土和微量元素特征与Kiruna型铁矿以及宁芜玢岩铁矿中磷灰石特征非常相似，表明它们具有相同的成因机理，反映出阿巴宫铁矿为岩浆分异的晚期矿浆贯入式成因；其硫同位素特征表明成矿物质源自幔源的玄武质岩浆。

Indeed, the Grand Canal was constructed partly utilizing the pre-existing channels connecting these lowland swamps and lakes (3) Several rivers have produced deltaic forms on the western side of the lakes;(4) A series of artificial islands have been constructed upon the natural bars or barriers located in the lakes and wetlands, and are locally termed Duo, Dun or Wei (meaning artificial bars or crossways in Chinese).

钻孔B/M界线之下(4078 m～4530 m)的泛滥平原河湖相沉积物中局部地段富含铁锰鲕粒，其主要矿物组成为蛋白石、铁的氢氧化物(包括纤铁矿、水纤铁矿、针铁矿、水针铁矿，统称褐铁矿)、铁锰氧化物(包括硬锰矿和软锰矿，以硬锰矿为主)及极少量的细小碎屑矿物(钾长石、蚀变黑云母、含铁白云母、锆石、独居石、金红石和含钛磁铁矿)。

The dehydration and transformation into suanite of decomposed of szaibelyite at about 700℃ is the main reason of ludwigite weight loss, It was found by XRD that paigeite and magnoferrite are the most stable component without phase tromsformation during oxidizing roasting.

硼镁石在700℃左右分解脱掉结构水形成遂安石，硼镁石的分解是造成硼铁矿大量失重的主要原因。通过XRD分析可知矿石中的镁铁矿相、硼铁矿相为最稳定相，在硼铁矿原矿焙烧过程中不发生相变。为硼铁矿烧结-冶炼工艺提供了必要的理论依据。
