角岩

The main rock types are two-mica quartz schist and plagioclase amphibole schist.

主要岩石类型为二云石英片岩和斜长角闪片岩。

The distribution of the newlyformed minerals and melt is restricted by the texture of the started amphibolite.

斜长角闪岩的原岩结构决定了实验产物中新生矿物和熔体的分布。

本文首先对顺层边坡的层状岩体及其中的层理面和不连续面进行了分析，对其应力应变进行了研究，得出了顺层边坡的稳定性不仅与岩体中岩石的强度有关，还与岩体中层理面及不连续面的内聚力、内摩擦角及其倾角有关；论文建立了层理面和节理面的地质力学模型，讨论了其力学参数变化对边坡稳定性的影响，并在此基础上将层理面和节理面归纳为顺层边坡稳定性的结构面影响因素，同时讨论了影响顺层边坡稳定性的其他因素，从而得出顺层边坡稳定性的评价预测指标。

Finally, it can be concluded for the first time that there was a large time gap between diagentic process of the volcanic rocks related to the Dapingzhang VHMS deposit and the ore-forming process, then a ore-forming model of the Dapingzhang deposit can be made, that is, the deposit passed through two important stages: the ore-forming metals concentrated during formation of the Early Palaeozoic spilite-quartz keratophyre on the island-arc belt, and the mineralization caused by the Late Palaeozoic magmation.

最后，首次提出与块状硫化物矿床有关的火山岩成岩过程和成矿过程可以有较大的时间间隔。在此基础上建立了大平掌矿床的成矿模式，并认为成矿作用可能经历了两个重要阶段，即早古生代岛弧型细碧岩-石英角斑岩建造形成过程中成矿元素的初始富集和晚古生代岩浆活动最终导致成矿。

Dapingzhang copper-polymetallic deposit hosted in spilite-quartz keratophyre formation is volcanic-hosted massive sulfide deposit, which formed during the Late Carboniferous and are contemporary with the intrusion of granodiorite-porphyry.

Along the low-angle overthrust Early Permian marble and Early Triassic sandy slate were thrust southward over Paleocene-Eocene purplish red conglomerate of the Paleocene-Eocene Fenghuoshan Group and brick-red sandy conglomerate of the Oligocene Yaxicuo Group, forming many klippen of varying scales, and thick fault brecci.

沿低角度逆冲断层，早二叠世大理岩和早三叠世砂板岩自北向南逆冲推覆于古新统—始新统风火山群紫红色砾岩和渐新世砖红色砂砾岩之上，形成大量不同规模的飞来峰；沿主逆冲断层发育厚层断层角砾岩与断层泥，局部形成碳酸盐质糜棱岩。

Ore deposit, have been studied detailly; the orebody pattern (sedimental bedded ores combined with stringer ores of hydrothermal origin) is also outlined; four metallogenic epoches are devided; the zoning of mineralization (including zones of ores, elements, mineral assemblages and temperature of mineralization) have been depicted; the main types of wall-rock alteration are characterized as propylitization of basic rocks and pyritization-sericitization-silicification of acidic pyroclastic rocks; the origin of ores and seven kinds of main minerals have been studied; and the metamorphism and deformation of orebodies is thought mainly due to the shearing and the intrusion of subvolcanic rocks

Home position shear tests of slope rock, point loading tests and indoor AMD simulation action tests in XingQiao concave slope had show shearing strength and coherence between body layers of quartz sandstone decrease by 13.2%~21.3% after attacked by AMD, the angle of internal friction between layers is decreased by 5.0%~7.5%, in general, AMD affects the rocks mechanical property at range of 60~100m interior the perpendicular slop. Data analysis shows: 1 The actions to slope are major focused on zone of weakness, shearing strength of slope foot and AMD centre are reduced by 52% and 64.7% separately. 2 The explosion stress wave of long distance field has obviously increasing influence to disturbance amplitude value of slope with increasing of the slope height and distance, the response of the top of slope and fault region are obvious as well as damage effect; the foot of slope is with smallest disturbance amplitude value, the disturbance amplitude value of the step close to free face is obviously bigger than the interior of slope. 3 With the coupling effect of the AMD and explosion loading, the stress distribution inside of slope mainly presents characters of explosion stress field; the area affected by AMD becomes a weak area of shearing stress.
