华力西期

在华力西期造山运动（M1）中，古生代岩石受到了低级变质作用（绿泥石带）。

Paleozoic rocks were affected by low-grade metamorphism ( chlorite zone ) during Variscan orogeny ( M1 ) .

辉绿岩、煌斑岩、花岗斑岩及石英脉形成于华力西期以后。

The diabase , lamprophyre , granite porphyry and quartz veins are formed after Variscan period .

在时间上，寒山金矿的成矿时代为339±10Ma，与寒山辉长岩同属华力西期，而且成岩时代早于成矿时代，因此推测寒山辉长岩可能为寒山金矿提供了热源。

The ore-forming age of the deposit is 339 ± 10 Ma , being of Hercynian too . The petrogenic age is earlier than the ore-forming age , possibly suggesting that the rock body provided heat for the deposit .

华力西期构造作用，使该区断裂活动加剧，发生大面积的岩浆侵入。

Variscan tectonism made fault activity in the region intensified and occur a large area of magma intrusion .

后底洞金矿床产于二叠纪柯岛组变质岩系与华力西期辉长岩体内外接触带。

The Houdidong Au deposit occurred in the Permian , Kedao Formation contact zone between metamorphic rock series and Variscan gabbro body .

由此可见，古陆间歇性活跃、海浸持续稳定是本区华力西期构造发展的基本特点。

It follows that the Variscan tectonic development is characterized by the intermittently active ancient land and steady transgressions in the study area .

北部古生代褶皱带演化，早期表现出一个向北俯冲的大洋盆地的闭合，随后蛇绿岩向南仰冲和华力西期的陆内逆冲推覆作用；

The evolution of the former is marked by the closure of a northward subducting oceanic basin in the early stage , followed by southward obduction of ophiolites and intracontinental thrusting during the Varisecan ;

华力西期幔源玄武岩浆喷发，除本身带来部分深源矿质，并对矿源层改造、萃取矿质，形成第一期火山热液贫矿化。

The poor ore mineralization of volcanic hydrothermal solution for the first stage was formed during the Variscan , the eruption of basalt magma brought part mineral matters from deep source and extracting minerals by the reformation of its source bed .

继后其构造环境转化为碰撞造山环境，早期成分受到后期构造&岩浆作用的强烈改造，因而岩段内含有较多的华力西期、印支期，可能还有加里东期的侵入体。

Later , the structural environment changed into a colliding orogenetic one , the earlier composition was intensively reformed by the later structural-magmatic action , so that there are more Variscan , Indosinian , probably also Caledonian intrusive bodies in the rock member .

在吉林省的吉林地区中部和北部大面积森林覆盖区，分布着大面积华力西期、印支期花岗岩类，受传统成矿理论的束缚，这一地区成为有色金属矿产勘查的“处女地”。

There are large-area Variscan , Indo-Sinian granites in the central part of Jilin area , forest region of the northern part , Jilin Province . It is fettered by traditional metallogenic theory , this area is also called as a " Virgin soil " on the nonferrous metal exploration .

花岗伟晶岩型矿床主要形成于华力西印支期，大多数分布在地槽褶皱带内。

The deposits of the granitic pegmatite type were mainly formed in Variscan_Indosinian period , and most of them are distributed in geosyncline folded belts , especially in composite anticlines of folded belts .

它们是华力西&印支期板内逆冲推覆构造所形成的断裂变质岩。

They are fault metamorphic rocks formed in thrusting nappe structure inside continental plate during Variscan-Indonian Stage .

晚华力西&印支期及燕山期侵入岩体控制了造山型矿床的分布。

The intrusive rock bodies of the late Variscan to Indosinian and Yanshanian dominate the distribution of the orogenic type deposits .

中生代火山岩的基底主要为加里东褶皱系，其上还有华力西&印支期沉积盖层；

The basement of Mesozoic volcanic rocks in Fujian Province is mainly in the Caledonian fold system and is laid over the Variscan-Indosinian sedimental cover .

金矿物特征反映出本区金矿床的成矿物质主要来源于变质岩，成矿作用与华力西、燕山期中酸性侵入岩有关。

These show that the source materials of the deposits were derived mainly from the metamorphic rocks and that the metallization of gold is closely related with Variscan-Indosinian intermediate-acid intrusive rocks .

华力西&印支期发展演化为裂陷带，并褶皱造山使裂陷带南北向大规模收缩，形成复式倒转褶皱系。

During the Hercynian-Indochina epoch the marginal fault depression basin developed into a fault zone with strong press of north-south direction and formed a folded chain consisting of inverted composite fold system .

延边东部地区已发现多种金属矿产，这些矿产与下古生界地层，中生代火山岩，华力西&燕山期中酸性侵入岩、次火山岩，东西、南北及北东向深断裂带和火山构造密切相关

Many kinds of metallic minerals were discovered in the eastern part of Yanbian area , Jilin province These minerals are closely related with the lower Paleozoic strata , Mesozoic volcanic rocks , Variscan-Yanshanian intermediate acidity intrusive rocks , subvolcanic rocks , WE , NS , EN deep-fracture zones and volcano-tectonics
