This study shows that there are 4 kinds of volcanic facies in deep volcanics in north Songliao Basin: eruptive facies, overflow facies, volcanic vent facies and volcanic sedimentary facies. There are 4 volcanic eruption cycles: Huoshiling period, Shahezi period, Yingchengzi period and Quantou period. There are 4 structural evolution stages: north-south accumulation, west-east subduction, uplift mantle and thin crust, alternative open and close. There are 4 kinds of pool-forming patterns:(1) pattern with the migration along the unconformity and fault to the near crater;(2) pattern with the migration along unconformity and fault to the rift margin;(3) pattern with the migration along unconformity, fault and fracture to the source rock;(4) pattern with the migration of the deep gas along the deep and large fault to the volcanic trap.

Hypogene high thermal or deep source epi-mesothermal condition and it is not only stressed the mantle source simply but also the crust-mantle;②in order to guid ore exploration better the artificial classification of uranium deposits should be broken and uranium ore-forming system strengthened;③much attention should be paid to searching the diabase-hosted rich uranium ore in strongly argillized cataclastic zone;④attention should be paid to the influence of basement of volcanic basin on the uranium ore formation that should be undstood both in feeling and theoretically through the ore propect process;⑤relation of red basin with uranium ore formation can be made clear from analyzing tectonics, paleo-climate and time and it is not only theoretically important but also helpful to uranium ore prediction;⑥crypto explosive pipe is an uranium ore, rich uranium ore host structure and it is the next goal for uranium ore exploration in east China.
摘要文章论述了华东火山岩型铀矿找矿值得重视的地质问题:①铀成矿既可形成于浅源浅成低温条件,也可形成于深源深成高温或深源浅成中低温条件,在强调深源时,不是简单地认为是幔源就可以了,还必须强调壳幔作用的地质过程;②打破人为的&类型&划分,加强&铀成矿系统&的研究,更好地指导找矿;③研究基性脉体与铀成矿问题应注意构造、岩石矿物成分、成因、蚀变与成矿3大问题,注意寻找泥岩化作用强烈的破碎辉绿岩脉中的富铀矿;④火山盆地基底对铀成矿的作用主要是提供铀源,将基底对铀成矿的影响从感性认识推向理性认识,有效地指导找矿;⑤红盆与铀成矿关系可以从构造、古气候及时间分析研究中得出结论,它不仅仅是一个理论问题,而且有助于铀成矿预测;⑥隐爆角砾岩筒是铀成矿、成富矿的重要储矿构造,是华东火山岩型铀矿找矿的新领域。

Yanbian region lies in the eastern segment of north margin of North China slab, situating on the intersect point of North China, Sibiric and the pacific slab. Space and boundary of these slabs controls the Mesozoic volcanic-subvolcanic rock distribution, which restricts the epithermal-porphyry gold metallogenic series. Though many research of deposits have been done individually, the synthesize works are few.

Tectonic condition is the key factor for igneous rock reservoir, which produce crack and improve reservoir character, abundant generating rock is the foundation for igneous rock reservoir, lithology condition is the important supplement for igneous rock reservoir, it is easy for trachyte to produce crack.
综合分析构造条件是火山岩成藏的关键,其产生的裂缝改善了火山岩储层的储集性能;充足的油源条件是火山岩成藏的基础;岩性条件是火山岩成藏的重要补充,即粗面岩容易在构造作用下形成构造裂缝,最终形成火山岩油气藏。

By sutdy and gathering information, some important conclusions are presented:(1) Ruby deposits of marble type were located in the plutonic metamorphic zones of orogene where deep-seated fault structure is developed;(2) Genesis of the deposit belongs to the type of thermal-dynamic metamorphism;(3) Ruby-bearing rocks are calcic crystalline marbles, not magnesian marbles;(4) Amphiboles in ruby-bearing rocks arenot tremolites, but silica-poor alumina-rich and chrome-bearing calcic amphiboles.
目前,对于此类型矿床找矿相关的若干重要问题的认识,还相当模糊,主要表现在以下几方面:(1)对此类型矿床的产出构造背景认识不清;(2)认为此类矿床的成因类型为&气成一热液型&或&矽卡岩型&;(3)认为含矿岩石为镁质大理岩或镁质矽卡岩;(4)认为含矿岩石中的角门石为透门石。本文通过实际研究①和相关文献资料的搜集整理,分别对这些

The multiphase tectonic activities above clearly controlled the move and gather of salifying brine, the strongth of salt-forming and the deposition of salt-bearing strata. With the pass of time, the salt-bearing strata thickened gradually from northwest to east and southeast, and the distribution of the thickness trended towards complicated; the measurement of the halite deposition extended towards east too; in the early Palaeogene and the Neogene, strong multiphase tectonic activity was a disadvantage to salt-forming, but in the middle and late Palaeogene, weak multiphase tectonic activity, which resulted in slow and sustained subsidence of the basin, was greatly advantaged to it, especially to potash-forming.
古近纪和新近纪成盐卤水的迁移和聚集、成盐作用的强弱以及整个含盐系的沉积发育明显受到上述构造活动的控制:含盐系的厚度随时间由北西向东、向南逐渐增厚,且厚度分布逐渐趋于复杂化;石盐岩的沉积规模和范围也逐渐向东扩大;古近纪早期和新近纪强烈的构造活动对于成盐作用而言是一种干扰因素,而古近纪中、晚期相对较弱、导致盆地缓慢持续沉降的构造活动对成盐,尤其对成钾作用则极为有利。

Ceilings should be ac-cessible for cleaning, and ideally, the surface should he coved where ceilings and walls meet In many food-production areas, the ceiling must have thermal in-sulation This may be necessary either to prevent surface condensation or to reduce the energy costs of maintaining low environmental temperaturesWalls should also be insulated, to prevent surface condensation They should be free from rising damp and be protected, where appropriate, from damage by forklift trucks, by use of a guard rail In modern factories, there is always a coved surface where walls meet the floor It is also usual for there to be a coved surface where walls join at right angles.
