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。

These samples were collected along a main street across the urban area and a mountain route from foot to the top. Results demonstrate that the main magnetic minerals in the street dust are magnetite, maghaemite and haematite with some paramagnetic minerals. Plots of Mrs/Ms vs. Bcr/Bc and Xfd % vs. X ARM/SIRM indicate that the main grain size of magnetic minerals in the street dust are pseudo single domain. The results reveal that the Lanzhou city is more polluted in spring than in summer. The main pollution sources are anthropogenic activities (81.9%) and natural dust (18.1%), especially the former. The spatial distribution of pollution is controlled by the topography and weather conditions.
结果表明,兰州市街道尘埃中磁性矿物含量较高,主要磁性矿物是铁磁矿、磁赤铁矿和赤铁矿,并伴有少量顺磁性矿物;磁性矿物粒度主要是准单畴;市区污染春季较夏季严重,春季高频率的强沙尘暴可能带来了更多的磁性矿物;兰州市污染物的沉积和分布在很大程度上受到气象条件和地形地貌格局的影响,市区每个盆地东端高于其它地区;兰州市污染以人为活动产物为主,人为活动贡献约为81.9%,其中包含交通约22.6%的贡献,自然降尘贡献约为18.1%;特殊的地形和气象条件,使得兰州市区的大气环境容量比平原城市的环境容量小得多,进而导致严重的大气污染。

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.

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。
