The Earth crust of southeastern China underwent the multiple-periodic intense orogenisms,namely,the Shuehfengian,the Caledonian,the Indo-Sinian, and the Yenshanian orogenic movements,accompanied by the formation of the granitic rocks of the corresponding geological ages,and these granitic rocks are distributed along different structural systems in the corresponding tectonic zones.A brief outline is given about the petrographical,petro-chemical,and geochemical characteristics,and their distinct trend of...

The Earth crust of southeastern China underwent the multiple-periodic intense orogenisms,namely,the Shuehfengian,the Caledonian,the Indo-Sinian, and the Yenshanian orogenic movements,accompanied by the formation of the granitic rocks of the corresponding geological ages,and these granitic rocks are distributed along different structural systems in the corresponding tectonic zones.A brief outline is given about the petrographical,petro-chemical,and geochemical characteristics,and their distinct trend of progressive evolution of the granites of different ages,as well as their different metallo-genetic relations to certain mineral deposits.Results of the present researches show that the areas characterized by the development of multiple-cyclic and multiple-staged granite bodies are most favorable for tungsten,tin,and other related metallic mineralizations,which almost invariably are associated with small granite bodies of younger ages and latest stages.It is inferred that,in the long course of time,the multiple-periodic and multiplestaged granitizations cause the ore-forming elements,such as,tungsten,tin,beryl- lium,niobium,tantalum,etc.to be leached out from the crustal materials in deeper levels and to be successively and continuously concentrated in the small granite bodies in the upper levels,finally resulting in the formation of mineral deposits.

本文所阐述的中国东南部地壳系经历过雪峰期、加里东期、印支期和燕山期等多时代强烈构造运动,并相应地形成各时代的花岗岩类。它们在各期构造带中循构造体系作有规律地分布。文中对各不同时代花岗岩类的岩石学、岩石化学、地球化学和成矿专属性等方面的特征及其明显的前进演化关系进行了扼要地叙述。研究资料表明,多时代花岗岩发育的地区,往往对钨、锡等金属成矿最为有利,并且其矿化经常与晚期或晚阶段花岗岩相联系,此乃多期、多阶段的花岗岩化的过程中,促使钨、锡等成矿元素不断从岩石中浸出向上富集的结果。

Tectonites are the dynamo-metamorphysic rocks which are generally believed to form under tectonic stress along zones of faults, and the fabric elements of the rocks reflect the history of the deformation. Our past study of dynamic metamorphyism and tectonite is very superficial and scrappy, a systematical classification and brief review of tectonite can be given in present paper. Table 1 shows what is possibly the most widely accepted classification and nomenclature, the principle of classification of...

Tectonites are the dynamo-metamorphysic rocks which are generally believed to form under tectonic stress along zones of faults, and the fabric elements of the rocks reflect the history of the deformation. Our past study of dynamic metamorphyism and tectonite is very superficial and scrappy, a systematical classification and brief review of tectonite can be given in present paper. Table 1 shows what is possibly the most widely accepted classification and nomenclature, the principle of classification of these rocks is based on textural criteria and mineral composition. Rocks subjected to advanced cataclasis and dynamic metamorphyism are classified here into six categories, as follows: 1. The breccia and pudding stone consist of correspondent angular and cabochon fragments produced by tectonic fragmentation of pre-existing rock. The term of breccia and puddingstone is used for rocks containing fragments larger than about 1/2cm, fine gravel for those with fragments from 1mm to 1/2cm. 2. Cataclasites are rocks showing a cataclasitic texture without schistosity or preferred orientation. 3. Mylonites are rocks showing mylonitic texture with banding structure are preferred orientation. The banding structure is usually the alternation of different mineral compositions or different degree of granulation. 4. Phyllonites (Phyllite-niylonites) are rocks of phyllitic appearance, and phyllitic structure can be presented on the specimen. Iris clear that the phenomena of stress mineal and recrystallization in phyllonites are prevalent than mylonites. 5. Phyllites and schists are subjected to considerable extent of recrystallization, therefore the mineralogical reconstitution tokes place in these rocks. The general features that phyllonite-schist are formed by dynamic and regional metamorphism are very similar, both of them have been distinguished only through the methods of investigation on field. 6. Buchites (hyalomylonite, pseudotachylyte) are a specific tectonite. The glassy rock is produced by melting in high temprature, and it is generally of rare occurrence.

依据岩石结构和矿物成分相结合并参照成因的原则,本文提出一个构造岩分类命名新方案。大体分为六大类:(一)角砾岩—磨砾岩类,后者是对压扁,滚动和园化的断层角砾岩的一个新的命名。(二)碎裂岩类,再细分为碎斑岩、碎粒岩和碎粉岩,其粒级相当于沉积岩中的粗砂、细砂和细粉砂。(三)糜棱岩类,又划分出粒化岩、粗糜棱岩和起糜棱岩,其粒级可与碎裂岩类相对比,但均具优选方位。(四)千枚糜棱岩类,按结构特点还详分为千枚糜棱岩、变余糜棱岩、硬板岩、变晶糜棱岩和片麻糜棱岩等。(五)构造片岩类,与区域变质岩中的片岩和千枚岩极其相似,故可用变质岩的一般命名原则分类。(六)玻化岩类,系剧烈变形高温熔融又迅速冷却的产物。构造岩的形成都是同构造运动、力学性质密切相关的。

In this paper the advance of a working face is considered as a mechanical model moving in a solid medium. Based on the results of field observations, the authors suggest that the distribution of roof pressure in front of and behind the working face may be divided into eight zones, i. e. zone free from the abutment pressure, zone of slight influence of front abutment pressure, zone of intensive influence of abutment pressure, zone of maximum roof pressure, zone of reduced pressure, zone of relieved pressure,...
