In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

东莫扎抓铅锌矿床矿体呈似层状展布，产状严格受到矿区逆冲断层的控制，赋矿围岩为上三叠统结扎群波里拉组灰岩和下-中二叠统开心岭群尕迪考组灰岩，发育强白云石化和弱硅化，矿物组合简单，主要为闪锌矿+方铅矿+黄铁矿+白云石+方解石+重晶石，矿石结构以皮壳状、草莓状等胶状结构和他形粒状结构为主，矿石构造为浸染状、角砾状、团块状和脉状。

In this research project, we have got a series conclusions:(1) there is no excess argon in the high-pressure white micas being in the orthogneiss;(2) The distribution of excess argon in eclogite is positive correlative with the ratio of Mg/, but negative with the ratio of Na/;(3) The in-situ analyses by using the method of laser probe 39Ar-40Ar show that the age radius from central to margin in a single grain of high-pressure white mica in eclogite;(4) There is no any evidence to prove that the excess argon in eclogite comes from fluid;(5) The excess argon in eclogite inherited from primitive rock during high-ultra high pressure metamorphism;(6) There is no excess argon in the eclogite when its surrounding rock is carbonate.

本项目用综合手段，研究了高压白云母中过剩氩的来源、赋存、分布与岩性、产状、矿物元素和矿物显微结构之间的相关关系，以确定过剩氩在高压白云母中赋存的主要控制因素。初步得出了以下结果：1、高压变质的正片麻岩中的白云母中不含过剩氩；2、高压白云母中过剩氩的赋存和Mg/有着正相关关系，而和Na/呈负相关；3、激光微区氩-氩分析表明，榴辉岩中的单颗粒多硅白云母存在年龄梯度；4、初步否定了高压白云母中过剩氩来自于流体的说法；5、初步认定，榴辉岩中多硅白云母中过剩氩主要是在高压-超高压变质过程中由内部继承的；6、在阿尔金及柴北缘等地围岩为碳酸岩的榴辉岩中的高压白云母不含过剩氩。上述研究结果将推动过剩氩成因研究走向深入。

The conventional 40Ar/39Ar age of muscovite in high-pressure metamorphic orthogneiss, surrounding rocks of the Qinglongshan eclogite, is identical with its Rb-Sr and Sm-Nd ages.

作为东海青龙山榴辉岩围岩的高压变质的正片麻岩，其白云母的常规~(40)Ar/~(39)Ar年龄和Rb-Sr、Sm-Nd年龄一致，激光微区Ar同位素分析表明，白云母的Ar同位素分布也是均匀的。

In the induction caving roof, the quantitative inspection have been done by the digital digital panoramic borehole camera system. The quantum study are applied to inspecte the crack occurrence and width from the corresponding relation between 3-D image and its spatial coordinates. And the system provide the method to calculate, account and analysis of the crack parameter.

采用数字式全景钻孔摄像系统宏观探测顶板围岩在耦合诱导致裂失稳崩落的裂隙形态，从裂隙的三维图像与空间坐标关系，对裂隙的产状、隙宽和迹长等参数进行了定量的数字化探测、处理与还原。

The reseach results provide that, to the sysytem of digital panoramic borehole camera, it is a effective method to detect the crack occurrence, width and length from the visible and quantitative. It is advantage to handle emptied areas throught induce fracturing caving in the roof, it is saied the induce couple technology of mining and blasting.

分析结果表明，数字式全景钻孔摄像系统可以直观可视和定量精细描述裂隙的形态，回采扰动和强制爆破诱导耦合技术，从裂隙发育、扩展以及裂隙的演化，有利于顶板围岩致裂失稳崩落，从而形成诱导崩落顶板处理空区的目的。
