Cathodoluminescence and δ〓O、δ〓C values of the sparites of geopetal structures within fossil brachiopods indicate that the sparcalcites were formed in equilibrium with various stages of postdepositional digenesis or catagenesis with each stage's δ〓O of interstitial water different.
3碳酸盐岩早期成岩胶结物或孔洞充填中的亮晶方解石是除腕足化石外获取碳酸盐岩原始氧、碳同位素组成的又一种常用样品。但本论文研究发现,龙门山地区碳酸盐岩的成岩后生改造具有多期多次现象,不同改造期次的流体之间存在明显的δ〓O差异,但无明显的δ〓C差别。

In this research project, we have got a series conclusions:(1) there is no excess argon in the high-pressure white micas being in the orthogneiss;(2) The distribution of excess argon in eclogite is positive correlative with the ratio of Mg/, but negative with the ratio of Na/;(3) The in-situ analyses by using the method of laser probe 39Ar-40Ar show that the age radius from central to margin in a single grain of high-pressure white mica in eclogite;(4) There is no any evidence to prove that the excess argon in eclogite comes from fluid;(5) The excess argon in eclogite inherited from primitive rock during high-ultra high pressure metamorphism;(6) There is no excess argon in the eclogite when its surrounding rock is carbonate.
本项目用综合手段,研究了高压白云母中过剩氩的来源、赋存、分布与岩性、产状、矿物元素和矿物显微结构之间的相关关系,以确定过剩氩在高压白云母中赋存的主要控制因素。初步得出了以下结果:1、高压变质的正片麻岩中的白云母中不含过剩氩;2、高压白云母中过剩氩的赋存和Mg/有着正相关关系,而和Na/呈负相关;3、激光微区氩-氩分析表明,榴辉岩中的单颗粒多硅白云母存在年龄梯度;4、初步否定了高压白云母中过剩氩来自于流体的说法;5、初步认定,榴辉岩中多硅白云母中过剩氩主要是在高压-超高压变质过程中由内部继承的;6、在阿尔金及柴北缘等地围岩为碳酸岩的榴辉岩中的高压白云母不含过剩氩。上述研究结果将推动过剩氩成因研究走向深入。

And whether is it necessary to redefine the geotectonic pattern in southern China? In 1993, the authors discovered firstly the late Paleozoic radiolarian silicalite in the "Shuangqiaoshan Group", which, as we know, is a block within the ophiolitic mélange. In 1996, the authors discovered again the late Paleozoic fossils in the other rocks of "Shuangqiaoshan Group" and "Zhitang Formation" of Lower Sinian Series in the ophiolitic mélange. At the same time, the authors discovered firstly the early Paleozoic chitinozoa fossils.
因此,再次将"板溪群"是否是前震旦纪的一个变质地层单位、江南古陆是否存在以及华南大地构造格局是否需要重新厘定等问题提了出来。1993年笔者于赣东北蛇绿混杂岩带内的"双桥山群"岩块中,首次发现了含晚古生代的放射虫硅质岩。1996年又在该混杂岩带多处的"双桥山群"岩块和"下震旦统志棠组"中找到了含晚古生代的放射虫硅质岩,还首次在"登山群拔竹坑组"中发现了早古生代的几丁虫化石。

The correlation analysis demonstrates that the hydroxyl content of omphacite is correlated positively with the MgO, TFeO and Al2O3 contents, and negatively with the Na2O content of the whole rock and the Na2O and TFeO contents of omphacite, but is not related with the peak metamorphic conditions.
相关性分析显示,绿辉石的结构水含量与全岩的Mgo、TFeO、Al2O3,含量成正相关,与NaO成反相关,与绿辉石的NaO、TFeO含量成负相关,与榴辉岩的峰期变质条件无关;与其它类型榴辉岩相比,多硅白云母榴辉岩中绿辉石的结构水含量较高,平均为339ppm。

The absorption spectrum center wavelength of dolomite is near 232 μm is shorter than 235 μm of limestone,and thus RBD7 and RBD8 can be employed effectively to identify dolomite and limestone,respectively. Felsic rocks show AlOH and Fe3+ absorption characteristics in the VNIRSWIR region,while the maficultramafic rocks show Fe2+ and Fe,MgOH absorption features,hence the use of different valence state of iron and secondary minerals can distinguish them:ASTER band2/band1 represent Fe3+ distribution,ASTER band2/band1 represent the Fe2+ distribution,RBD6 can estimate the AlOH mineral abundance. Psammitic/pelitic schist containing phengite,chlorite,stilpnomelane,as well as the weathered surface covered by clay minerals,exist characteristic absorption spectrum in the 221 μm(band 6),and has a high reflectance in 165 μm(band 4),while the blueschist/greenschist show high reflectance in the 221 μm(band 6),and it exit low reflectance in 165 μm(band 4),and blueschist/greenschist appear low ASTER band4/band6 ratio.
白云岩的CO2-3吸收谱带中心波长位于232〖KG*3〗μm,与灰岩的CO2-3 吸收谱带中心波长位置235 μm相比,具有向短波长方向移动的特点,据此可以利用RBD7、RBD8分别有效的识别白云岩和灰岩;长英质岩石显示AlOH和Fe3+ VNIRSWIR吸收特征,而基性超基性岩石显示Fe2+和Fe、MgOH特征,利用不同的铁价态和次要矿物可以区分它们:ASTER band2/band1代表了含Fe3+矿物分布信息、ASTER band5/band4代表了含Fe2+矿物分布信息、RBD6可以估计AlOH矿物的丰度;砂质/泥质片岩含较多的多硅白云母、绿泥石、黑硬绿泥石以及风化后表面覆盖的其它粘土矿物,在221 μm(band 6)存在有特征的吸收谱带,并且在165 μm(band 4)具有较高的反射率,而蓝片/绿片岩在221 μm(band 6)反射率较高,不具有明显特征吸收谱带,同时其在165 μm(band 4)反射率较低,因此蓝片/绿片岩ASTER band4/band6 比值低。

A total of 29 groups of isotope age data such as Sr-Nd isotope age data and Nd model age data of igneous rocks, including granites, volcanic rocks, dyke swarms, cumulates, and ophiolites, formed in different periods of time are reported in this paper, which show the following two features:(1) igneous rocks including ophiolites formed in this area since 800 Ma BP all have high eNd and low Sri, with most Sri values centered in the range of 0.7045 to 0.7060 and eNd values in the range of 1 to 5, and (2) most of the TDM ages are in the range of 800 to 600 Ma, with only a few at 1000 Ma.

Peridotite xenoliths from Nüshan, Hannuoba and the Subei basin of the North China block have much lower water contents than those from other localities of the world (South Africa craton, New Mexico, Colorado plateau and basin and Range province of USA, South Mexico, French Central Massif and West Kettle of Canada). This difference is probably induced by the thermal erosion of asthenosphere during Mesozoic-Cenozoic period in the North China block.
结合已经发表的安徽女山和河北汉诺坝的橄榄岩数据,对比世界上其他地区橄榄岩的数据来看,华北的岩石圈地幔具有低的水含量:华北橄榄岩的单斜辉石水含量多<200×10^(-6),而世界上其他地区(包括南非克拉通、美国新墨西哥地区、美国Colorado高原、美国盆岭省地区、墨西哥南部、法国中央地体以及加拿大West Kettle地区)橄榄岩的单斜辉石水含量多>200×10^(-6);华北的斜方辉石水含量多<100×10^(-6),而世界上其他地区多>100×10^(-6);华北的橄榄岩全岩水含量多<50×10^(-6),而世界上其他地区多>100×10^(-6)。
