The most polluted areas is near Tianjin second gasworks and around sewage river as well as sewage irrigation area. So we can conclude the major sources of pollution is atmospheric deposition and sewage irrigation. Second, It is positive correlation between the heavy-metal contamination and layered silicate minerals, while it is negative correlation between heavy-metals and quartz , feldspar as well as other minerals.

二、重金属污染元素含量与层状硅酸盐矿物含量呈正相关，而与石英长石等矿物含量呈负相关，充分说明污染元素主要赋存在层状硅酸盐矿物中，这与矿物自身的结构有着密切的关系，层状硅酸盐矿物具有很大的层间域，有利于对其他物质的吸附作用。

It is found that there is a mineral association, micro-crystal muscovite and phengite, in this deposit. The mineral assemblage contains about 80% micro-crystal muscovite and about 20% phengite. Their crystallinity is very high and their polytype is 2M1. Both of them are dioctahedral because the d and b of micro-crystal muscovite and phengite are 0.1502 nm, 0.9012 nm and 0.1505 nm, 0.9030 nm, respectively. For their d and b are larger than those of common muscovite, the reason why Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+) are high in the ore is that Al(superscript 3+) in the octahedron is replaced by Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+), and this is a phengite series mineral association formed through isomorphic replacement.

该矿物组合中的微晶白云母和多硅白云母结晶度高，多型为2M1，其含量分别为80%和20%左右；二者都属二八面体型白云母类矿物，但d060和b值偏大，微晶白云母的d060=0.1502nm，b=0.9012nm，多硅白云母的d060=0.1505nm，b=0.9030nm；微晶白云母矿铝含量较低、铁镁含量较高，其原因是白云母晶体铝氧八面体中的Al离子被Fe、Mg等离子所取代，这一矿物组合是通过矿物类质同象作用所形成一种多硅白云母系列矿物。

It must be pointed out that the silverbearing tetrahedrite and freibergite of the Caijiaying deposit have about the same iron and zinc content, but differ from the Fe_rich and Zn-poor tetrahedrite and freibergite in the Xiasai,Lamo, Mount Isa and Langdal deposits.

按国际矿物学协会新矿物及矿物命名委员会的矿物命名原则，黝铜矿族矿物所含的Fe、Zn、Hg、Cd、Mn等不可作为矿物种的命名元素。

Recently a mantle mineral group including about 70～80 subtipys of mineral have been discovered from podiform chromitite in Tibet,China.

最近在西藏罗布莎村豆荚状铬铁矿石中发现一个由70~80种矿物组成的地幔矿物群，其中包括新矿物罗布莎矿，还有金刚石、柯石英、碳硅石、方铁矿、以及Fe-Si相矿物。

For a 1116Kg chromitite and a 384Kg mantle peridotite sample, by heavy mineral separation and picking up under a binocular microscope following productions are obtained: the UHP minerals including moissanite and over 1000 diamond grains are discovered firstly from the Kangjinla chromitite orebody Cr-11, which is far more abundant than the Luobusa district; a series of unusual mantle minerals like moissanite and a great deal of diamond grains are discovered firstly from the host rocks of chromitite orebody Cr-11, providing the foundation of discussing the chromitite origin and its relation with the host rocks; besides the UHP minerals like moissanite and diamond, various special mantle minerals are revealed from the chromitite orebody Cr-11 and its host rocks including some native elements, alloys, oxides, sulphides, silicates, carbonates, and tungstates.

2人工重砂发现铬铁矿和地幔橄榄岩中的金刚石等特殊地幔矿物。1116 Kg铬铁矿和384Kg地幔橄榄岩大样经人工重砂分选和双目显微镜下挑选矿物，取得如下成果：首次在康金拉11号铬铁矿体中发现了上千粒金刚石，以及碳硅石等强还原环境的超高压矿物，数量远远超过在罗布莎铬铁矿矿区中发现的金刚石；首次在康金拉11号铬铁矿矿体的近矿围岩中发现了大量金刚石和碳硅石等一批异常地幔矿物，为探讨铬铁矿的成因及与近矿围岩地幔橄榄岩的关系奠定了基础；除挑选出金刚石和碳硅石等超高压矿物，在康金拉11号铬铁矿矿体与围岩地幔橄榄岩中还发现了自然铁球、金属互化物、氧化物、硫化物、硅酸盐等一批异常地幔矿物。

In greywacke, the content of clay mineral often higher than 15%, clay mineral come from former clay mineral in sediments and their transformation. Clay minerals show plasticity. Clay mineral can damage the pore content of reservoir through distorting and filling into pore easily. These reservoir show low pore content and low permeability.

杂砂岩中的粘土矿物主要是沉积原生粘土矿物和原生粘土矿物转化形成的新生粘土矿物，粘土矿物在储集层中主要表现为可塑性，容易压实变形并充填到孔隙当中损害储集层物性，储集层物性主要表现为低孔低渗。

The split between the two groups can hardly be papered over.
