The meso - neoproterozoic tectono - stratigraphic division on the epicontinental mobile belt in northern liaoning province 关于辽宁北部陆缘活动带中新元古代构造地层划分

In the taiyuan stage of the early permian , north china sea is connected with qilian sea to form uniform epicontinental sea deposit 早二叠世太原期,华北海与祁连海贯通,形成统一陆表海沉积阶段。

The feature of the sedimentary succession of the epicontinental sea basin in the study area was analyzed by means of the stochastic math model , markov chain 摘要运用马尔柯夫链随机性数学模型对研究区陆表海盆地沉积序列特性进行了分析研究。

Their original rocks are volcanic rocks , epicontinental clastic sedimentary rocks , and ophiolite of volcanic and island arc tholeiitic series or calcium alkali series 其原岩岩石类型有火山岩,陆缘碎屑沉积岩,火山、岛弧拉斑系列或钙碱系列火山岩、蛇绿岩等。

Under the tectonic backgrounds of island arc belt , fore - arc trench belt , back - arc basin , and epicontinental active belt of late paleozoic , it has different volcanic rock characteristics 在晚古生代岛弧带、弧前海沟带、弧后盆地或陆缘活动带等构造环境下发育有不同的火山岩组合。

The depositional environment of the upper paleozoic in the ordos evoluted from the epicontinental sea to the fluvial - delta . the change of the depositional environment and eustacy controlled the main depositional systems in the research area 上古生界沉积环境演化过程总的是由陆表浅海逐渐变为陆相的河流?三角洲,海平面升降和海水进退控制了区内主要的沉积体系和沉积相类型。

According to tectono - metallogenic setting in combination with main mineral distribution and metallogenic types and ore - forming epochs in this orogenic belt , the authors used the theory of metallogenic series to divide the deposits of the north qilian early palaeozoic convergent epicontinental cu , pd , zn , w ( mo ) , au , ophiolite metallogenic belt and the south qilian early palaeozoic epicontinental rifting cu , ni ( pt ) , cr , au , rare elements and pyrite metallogenic belt into six series 文章依据成矿构造环境,结合区域主要矿种分布及其成矿类型和成矿时代等特徵,应用矿床成矿系列理论,将祁连造山带北祁连早古生代汇聚陆缘铜、铅、锌、钨(钼) 、金、蛇蚊石成矿带和南祁连早古生代陆缘裂解带铜、镍(铂族) 、铬、金、稀土、黄铁矿成矿带中的矿床划归为6个成矿系列。

According to sedimentary characteristics of the carboniferous taiyuan formation in feicheng coal field , including lithology , size distribution , sedimenta ry structure , geochemistry and paleontology etc . , the carboniferous paleoenvironme nt of this area is divided into carbonate open platform and tidal flat environme nt . it is recognized that the taiyuan formation is formed in the epicontinental c oast which is dominated by the tidal . the peat flat is the important paleoenviron ment for coal accumulation . the tidal channel destroys the coal bed . the pulsative vibration of the crust is the major factor which controls the evolution of the sedimentary environment and the coal accumulation 根据肥城煤田石炭系太原组的岩性、粒度分布、沉积构造、地球化学及古生物等沉积特征,将该区晚石炭世古地理划分为碳酸盐开阔台地和潮坪环境,认为太原组形成于潮汐作用为主的陆表海海岸,泥炭坪是成煤的重要古地理环境,潮渠对煤层有一定的破坏作用,地壳的脉动性振荡作用是控制沉积环境演化和聚煤作用的主要因素。
