epicontinental
1.The Ellsworth basin lay between the epicontinental basin and the marginal magmatic arc during the Devonian.
2.Study on coal accumulation under marine transgression events in the epicontinental basin of North China
3.Their original rocks are volcanic rocks, epicontinental clastic sedimentary rocks, and ophiolite of volcanic and island arc tholeiitic series or calcium alkali series.
4.In early Permian period,the epicontinental sea of North China Platform receded conti-nously to the south,thus the-coal accumulations of continental delta facies are generated inthe southeast of North China Platform.
5.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.
6.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
7.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.
8.Abstract: 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.
