黑山煤田封堵涌水孔段的浆液和注浆方法

黑山煤田处于沙漠边侧,地层有纯砂粒构成的、透水性较強的中细砂层,这类地层中如含有承压水时,会发生钻孔涌水,对于中细砂涌水钻孔,用泥浆冲孔时,可通过适当增大泥浆相对密度,来压制地下水涌出,ZK18-28孔是涌水孔,也是采用绳索取心钻进的孔,因此不宜使用高相对密度泥浆。用套管亦未奏效。若用注浆法,对于中细砂层是不适用水泥浆的。而溶液型浆液的注浆封堵中细砂层,在技术有可行性,对于涌水压力不大的孔,又有可用低强度,因而也是低成本的浆液,因此选择了比较亷价的水玻璃类的SPN浆液,并采用双隔离塞的注浆法,在ZK18-28孔中取得了封堵中细砂涌水层的初步封堵效果。     

实验室与田间条件下骨炭粉与海藻肥对镉污染土壤修复效果评价

本研究基于小麦、玉米、高粱籽粒及烟草烟叶镉(Cd)消减率、修复边际效率及土壤中Cd有效态含量的变化等对比了实验室与田间条件下骨炭粉与海藻肥对Cd污染农田土壤的修复效果。研究结果表明：骨炭粉与海藻肥使玉米、小麦、高粱和烟草对Cd的吸收、转运均有显著(P<0.05)降低作用;在田间条件下,骨炭粉与海藻肥对不同作物籽粒或烟叶的Cd消减率为16.2%~39.8%,可增加作物产量12.3%~38.6%。钝化剂对不同作物增产效果有一定差异,对小麦籽粒增产作用最为有效。研究发现添加钝化剂改变了Cd在土壤团聚体中的分布,使得Cd在大粒径团聚体中负载量增加,并且与对照相比,显著提高土壤pH(提高0.43~0.77),降低土壤Cd的有效性,有利于控制Cd在土壤植物系统中的迁移。总体而言,不同钝化剂的Cd污染土壤修复边际效率为3.99%~14.74%,同海藻肥相比,骨炭粉的修复边际效率较高。不同钝化剂在盆栽实验的修复效果优于田间实验的效果,可能是因为相比于田间实验,盆栽实验条件下根系的作用范围有限,钝化剂的作用效果较高。

Reactions and textures in grossular–wollastonite–scapolite calc–silicate granulites from Maligawila, Sri Lanka: evidence for high-temperature isobaric cooling in the meta-sediments of the Highland Complex

Grossular–wollastonite–scapolite calc–silicate granulites from Maligawila in the Buttala klippe, which form part of the overthrusted rocks of the Highland Complex of Sri Lanka, preserve a number of spectacular coronas and replacement textures that could be effectively used to infer their P–T–fluid history. These textures include coronas of garnet, garnet–quartz, and garnet–quartz–calcite at the grain boundaries of wollastonite, scapolite, and calcite as well as calcite–plagioclase and calcite–quartz symplectites or finer grains after scapolite and wollastonite respectively. Other textures include a double rind of coronal scapolite and coronal garnet between matrix garnet and calcite. The reactions that produced these coronas and replacement textures, except those involving clinopyroxene, are modelled in the CaO–Al₂O₃–SiO₂–CO₂ system using the reduced activities. Calculated examples of T–X_CO2 and P–X_CO2 projections indicate that the peak metamorphic temperature of about 900–875 °C at a pressure of 9 kbar and the peak metamorphic fluid composition is constrained to be low in X_CO2 (0.1<X_CO2<0.30). Interpretation of the textural features on the basis of the partial grids revealed that the calc–silicate granulites underwent high-temperature isobaric cooling, from about 900–875 °C to a temperature below 675 °C, following the peak metamorphism. The late-stage cooling was accompanied by an influx of hydrous fluids. The calc–silicate granulites provide evidence for high-temperature isobaric cooling in the meta-sediments of the Highland Complex, earlier considered by some workers to be confined exclusively to the meta-igneous rocks. The coronal scapolite may have formed under open-system metasomatism.

木兰山蓝片岩中两种文石的产出特征及其动力学意义

微米－纳米尺度显微超显微研究表明，木兰山蓝片岩中存在微米级粒间文石和亚微米级文石包裹体，它们是木兰山蓝片岩快速折返动力学机制的证据。并指出木兰山蓝片岩区硬柱石和绿纤石等Ca-Al硅酸盐矿物的缺失与本区变质流体中CO2浓度较高和（或）岩石中含方解石／文石有关。

Investigation of the Matrix Effect of Mg, Si, Ca, Sc, Fe, Y, La and Lu in Pyroxene Composition Synthetic Silicate Glasses by Ion Microprobe

The dependence of the count rate of singly charged secondary ions of the elements Mg, Si, Ca, Sc, Fe, Y, La and Lu on the bulk composition of the sample (known as the matrix effect) was systematically investigated for synthetic silicate glasses using a Cameca IMS 3f ion microprobe. Matrix elements in these samples, with the composition of a Mg-Fe-Ca pyroxene, comprised Mg, Si, Ca and Fe to which were added the minor elements Sc, Y, La and Lu (each at 0.1 atom %). The matrix dependence of all elements was determined quantitatively by ratioing their count rate response to the Ca or Fe yields of the sample. Measurements were conducted using four energy offsets: 0 eV, 40 eV, 80 eV and 120 eV (each 20 eV) with primary beam currents of between 0.5 and 3 nA. For the four minor elements investigated, a non-linear dependence of the absolute sensitivity factors on the Fe content was found at all the energy ranges studied. This matrix effect decreased with increasing secondary ion energy. For the major elements Mg, Si, Ca and Fe, linear as well as non-linear dependences of the absolute sensitivity factors on the Fe content were found, depending on the element and the energy level considered. Because of their importance in the geosciences, relative sensitivity factors of the elements under study relative to Si as reference element (in some cases also relative to Mg) were determined. For low energy ions, a Fe-dependent matrix effect also occurred. For Mg, Y, La and Lu, the matrix effect vanished for some values of the secondary ions energy range.
