Abstract ：
The Zijinshan ore field is situated in the southeastern part of China. in which contains the large Zijinshan highsulfidation Cu-Au deposit, the Luoboling porphyry Cu-Mo deposit, the Yueyang low-sulfidation Au-Ag deposit, the Longjiangting and the Wuziqilong tansitional Cu deposit, and the Xi'nan porphyry Cu-Mo prospect. Debates on genetic relationship among these deposits, especially the relationship between the Zijinshan Cu-Au deposit and the adjacent Luoboling deposit is a question of importance for further exploration in this ore field. In this contribution, the alteration mineralogy, alteration texture, zonation and mineral chemistry, in combination with shortwave infrared spectroscopy (SWIR) analysis of white mica were used to help focus exploration and assessment of hydrothermal deposits in the Zijinshan ore field. In this study, diaspore-pyrophyllite alteration zone, chlorite-sericite alteration zone and propylitic alteration zone were first identified in the deep drill core of the Zijinshan Cu-Au deposit, which gives way upward to quartzalunite-kaolinite zone, quartz-alunite zone and the silicic alteration zone. In the Xi'nan Cu-Mo prospect, diaspore-pyrophyllite alteration zone was first recognized in the shallow level with the chlorite-sericite alteration zone and propylitic alteration zone in the deeper level. Andalusite- sericite +/- diaspore alteration zone was first recognized in the upper part of the Luoboling Cu-Mo deposit and the deeper part of the Wuziqilong Cu deposit. It indicates that a pervasive occurrence of diaspore-pyrophyllite +/- andalusite alteration zones in the Zijinshan ore field, which may potentially represent a transitional environment between the top of porphyry alteration zones and the base of advanced argillic alteration zones. Minerals of the white mica group are extensively distributed in various alteration zones of the Zijinshan ore field. The SWIR analysis of white mica indicated that the wavelength position of the Al-OH (similar to 2,200 nm; wAlOH) absorption feature increases gradually from the shallow kaolinitedickite alteration zone to the deep potassic alteration zone. In the advanced argillic alteration zones, the range of wAlOH values of white mica is less than 2205 nm. Conversely, in the porphyry alteration zones, it always exceeds 2205 nm. It is evident that the andalusite-sericite alteration zone with higher wAlOH values (average of 2203 nm) is always proximal to the porphyry mineralization, which may act as indicators for deep porphyry prospecting. The results of electron probe microanalysis (EPMA) reveal that the early enrichment of Mg and depletion of Fe in white mica can be attributed to the preferential incorporation of Fe into iron oxides and iron sulfides in the potassic and propylitic alteration zones. Overall, there is a negative correlation between wAlOH and Al, while wAlOH exhibits a positive correlation with the sum of Fe + Mg + Mn. The distribution characteristics of alteration zones and the variation patterns of the wAlOH of white mica indicate that there are probably several paleo-thermal centers in the deep parts of the Zijinshan ore field, located respectively in the deep parts of the Xi'nan Cu-Mo prospect and the deep part of the Zijinshan Cu-Au deposit and the deep parts of the Wuziqilong Cu deposit, and the latest seems to be more fertile and deserves further exploration.

Abstract ：
采用溶液浸泡法制备地开石-甲酰胺插层复合材料。通过插层试验寻求最佳制备工艺,为研究区域的地开石开发和利用提供借鉴。采用X射线衍射(XRD)、红外光谱(FTIR)和热重-差热(TG-DTA)分析进行表征,结果表明,甲酰胺的添加量、溶液p H值、插层反应温度和插层反应时间均会影响插层效果。在弱碱性环境中,甲酰胺添加量越大,反应时间越长,越有利于形成插层复合材料。从经济效益考虑,在25℃,p H值为9条件下,5 mL甲酰胺对3 g地开石(即1.67 mL/g)进行插层反应24 h,可制得插层率高的地开石-甲酰胺插层复合材料。

Abstract ：
Potassium acetate (KAc) has been successfully intercalated into dickite through immersion method. Prepared complexes were characterized by XRD, FTIR, TG-DTA, XPS and SEM-EDS analyses. The effectiveness of intercalation and influencing factors were also analyzed. The results confirmed that KAc and H2O were successfully inserted into the interlayer of dickite. The results showed that intercalated rate of dickite by KAc were related to aging time, pH value, reaction temperature, and concentration of KAc solution. From the view of energy and environmental protection, reaction time for 24 h was enough to gain a satisfactory intercalation result. While a good intercalated complex can be obtained on the weak alkaline condition of pH value. A higher concentration of KAc solution was beneficial to intercalate and the reaction temperature below 100 degrees C was proved to be favorable for intercalation. (c) 2017 Published by Elsevier B.V.

Abstract ：
The thermal decomposition and de-hydroxylation process of dickite-potassium acetate (KAc) intercalated complex was studied using thermogravimetric (TG), differential thermal analysis (DTA), XRD and FTIR. The stability of intercalated complex was affected by heat treatment directly. The TG-DTA results showed that four changes had occurred at 64.5, 118, 301 and 406 A degrees C, which can be attributed to (a) the loss of adsorbed water, (b) loss of the water linked to acetate ion in the layer of dickite, (c) decomposition of KAc, and (d) loss of water through de-hydroxylation, respectively. The XRD and FTIR results showed that when the heating temperature exceeded 400 A degrees C, inner surface hydroxyls and inner hydroxyls lost gradually, generating amorphous meta-dickite. Further researches demonstrated that phase transition temperature of meta-dickite and mullite changed a lot through the intercalated KAc.

Abstract ：
地开石在陶瓷、涂料、化妆品及填料的工业应用中有着广泛潜力.在本研究中,挑选紫金山Au-Cu矿床中三种典型的地开石(透明、半透明和不透明)和一种矿区分布广泛的淋滤型地开石,通过电子探针(EPMA),X射线粉末衍射(XRD)、傅立叶红外光谱(FT-IR)和场发射扫描电子显微镜(FESEM)表征矿物学特征.EPMA成分对比分析表明,地开石纯度均较高,Al2O3和SiO2质量分数低,FeO质量分数低,白度很高,可以有效地应用到造纸工业中.XRD和FT-IR结果表明,不透明地开石结晶较好,有序度较高,随着透明度的增加,透明地开石的有序度降低,结晶较差.FESEM分析表明,不透明的地开石晶粒发育较好,片层之间堆积紧密,晶粒横向最大尺寸为5 μm,随着透明度的增加,晶粒横向尺寸减小,透明地开石的晶粒为0.2～1 μm;淋滤型地开石可见假六方状片层相互堆积,但由于酸性淋滤作用,片层上有很多小空洞,且片层的边缘溶解,堆积松散,这种淋滤地开石的间层有利于其他高分子材料插入,可用于制备地开石-高分子复合材料.此外,对紫金山Au-Cu矿床地开石的矿物学特征的研究,弄清了地开石之间的形成关系,以及与矿区的成矿关系.
