  rb
The samples were characterized by XRD, BET, DTA-TG, UV-Vis, and their photocatalytic properties were evaluated with two model pollutants, methylene blue (MB) and rhodamine B (RB), at room temperature.
      
For three tested samples, under UV illumination CCT01 has the highest activity for MB photocatalytic degradation, while in the case of RB, CCT02 is the most active photocatalyst.
      
Under visible light illumination, CCT005 has the highest activity for both MB and RB photocatalytic degradation.
      
Seven pore water samples were analyzed for their anion (Cl-, SO42-, Br-, I-) contents, cation (Na, K, Ca, Mg) contents and trace element (Li, B, Sr, Ba, Rb, Mn) contents.
      
However, elements of Fe, Co, Zn, Ni and Rb may catalyze the organic matter maturation.

The Mengyejing potash deposits, found in the "red" Mengyejing For-mation of Upper Cretaceous to Paleogene ages, are located in the southof the Lanping-Simao depression zone between the Ailaoshan and Lan-cangjiang faults. The salt sequence consists of mixed (sedimentary rocks characterizedby repeated occurrence of chemical evaporites and clastic sediments. Thetypical section may be subdivided into nine rhythmical layers which fallinto three compositional units, i.e., the upper and lower halite beds andmiddle potash member. Trace elements of the deposits have been studied rather systemati-cally. The average content of Br in halite is 127 ppm, in grey sylvite, 2060ppm, and in carnallite, 1399 ppm, with the exception of low Br contentin carnallite, that of the other two falls within the respective theoreti-cal value. The average amounts of Rb in sylvite and carnallite are respec-tively 50 ppm and 60 ppm. Although Rb in the sylvite is more than thatof the theoretical value from sea water, however, that in the carnallitefalls within the theoretical value. This shows that the parent brine wasof marine and deep-level water source. The red sylvite associated with carnallite has abnormally low Br(1229 ppm) and abnormally high Rb (67 ppm) as compared with primarygrey sylvite. These facts can be explained satisfactorily if it is a secon-dary leaching product from carnallite. Br in the halite profile increases upward slightly. But there is evid-ent rising of the Br curve at the points where the lower or the upperhalite bed passes into the middle potash member with saw-like variationin between, indicating that the brine giving rise to the potash precipita-tion has reached the "dry-lake" stage. Strontium and boron have substituted respectively for Ca~(++) and SO_4in anhydrite, thus denoting the diluting of the brine, while celestite, bo-racite and the presence of boron in absorption form are related closelyto the potash layers and may indicate its concentration in related salts.

勐野井钾盐矿床位于云南兰坪、恩茅拗陷带的南部。该带地处藏滇印支地槽褶皱系中段,点苍山、哀牢山断裂带以西,澜沧江断裂带以东。区内发育有巨厚的中新生代红色碎屑岩和含盐建造,本区的主要含盐层为晚白垩世至老第三纪勐野井组。 勐野井组有上下两套含盐层,中部为棕红色钙泥质粉砂岩,下含盐层在区域上是含膏层;上含盐层为石盐岩夹钾盐透镜体。下覆地层是上白垩统扒沙河紫红色石英砂岩,上覆为老第三系等黑组棕红色粉砂岩。矿区为一向斜构造呈北西—南东向分布,盐矿体呈穹窿状,石盐层平均厚196米,钾盐厚29米,NaCl平均含量71.67% KCl 8.70%,为混有碎屑物的氯化物型钾盐矿床。 本文研究了富钾盐层剖面结构、碎屑物沉积特征、溴、铷、锶、硼等微量元素赋存规律及其在寻找钾盐矿床工作中的标志意义,并探讨了盐矿床的成因。全文蒙袁见齐教授审阅,并提出修改意见,在此表示感谢。

The endometallogenetic tectonogeochemisty means that endometallogenetic process has to possess tectonogeochemical conditions both temporally and spatially, or means the tectonogeochemical processes for generating endogenic mineralization. The tectonogeochemical conditions or processes are different, and the metallogenetic processes are distinct. On the basis of this defference and distinction it is that the types are divided.

The endometallogenetic tectonogeochemisty means that endometallogenetic process has to possess tectonogeochemical conditions both temporally and spatially, or means the tectonogeochemical processes for generating endogenic mineralization. The tectonogeochemical conditions or processes are different, and the metallogenetic processes are distinct. On the basis of this defference and distinction it is that the types are divided. These types are called tectonogeochemical type of endometallization.Xianghua place belongs to massive swell district of Diwa region. Its faulting and magmatic intrusion are very intensive, the metallization developed very well. The core part in this massive swell district possessed the double textures (the flysch formation of geosynclinal type and carbonated formation in marine facies of platform type).The ore-forming elements of the enrichment are Li, Rb, Cs, Be, Nb, Ta, TR, U, Th, W and Sn as well as Cu, Pb, Zn, Ag, In, Cd, Te, F, As, B, Sb, S, etc. That is' lithophile-chalcophile elements are concentrated into ore deposits. For this reason, Xianghua place is divided into the endometallogenetic tectonogeochemical type of the lithopile-chalcophile elements (The mixed type) at the massive swell type(The geodome type).

内生成矿构造地球化学是指内生成矿作用在时间上和空间上所应具备的构造地球化学条件!即指产生内生成矿的

Geochronological studies of rocks in Lianhwashan region by Rb—Sr dating show that the ages of the acidic intrusive and volcanic rocks are very similar. The isochronal age of them is about 135M. Y. And the age of the formation of the tungsten ore deposited in hydrothermal solution is also close to this isochronal age.

Rb—Sr法地质年代学研究表明,莲花山钨矿区内的花崗岩和酸性火山岩是同时形成的。其等时线年龄分别为:137.2±2.5百万年,(Sr初始值(Sr~(87)/Sr~(86))_0=0.70696±0.00056);135.8±7.3百万年,(Sr初始值(Sr~(87)/Sr~(86))_0=0.70613±0.00035)。成矿时代接近成岩时代。
