环渤海地区及海域中、新元古界分布特性分析
|
摘要
中朝板块从震旦纪(680Ma)开始分裂为华北块体(NCB)与胶辽朝块体(JLKB),环渤海地区及海域元古界主要分布在该板块。华北块体为环渤海地区的陆上区,由于燕辽裂陷槽在华北北部展布,主要发育有中元古代地层;渤海海域区分布在胶辽朝块体上,完全缺失中元古代地层。1000Ma芹峪运动后,华北块体主体抬升为陆,新元古代华北板块沉积范围主要分布于东部,而胶辽朝块体却有较完整的新元古代沉积。在收集野外露头资料的基础上,借助地震、测井数据,对全区中、新元古代沉积特征做了综合分析,特别对争议比较大的海域区作出合理预测。
Sino-Korean Plate has been split into North China Block(NCB)and Jiao Liao Korean Block(JLKB)since Sinian Period(680 Ma).The Proterozoic group of Bohai Sea surrounding area and its sea area are mainly distributed in this plate.NCB is the land area of Bohai Sea surrounding area and mainly deposit because of Yan-Liao Aulacogen distributing in the north area of North China.Bohai Sea Area is distributed in Jiao Liao Block with completely missing of Proterozoic strata.After 1 000 Ma Qinyu movement,the main part of NCB was lifted to be the land,and the deposition of NCB in Neoproterozoic is mainly distributed in eastern part while JLKB has a fairly comprehensive Neoproterozoic deposit.On the basis of collecting field outcrop data,this paper makes a comprehensive analysis on sedimentary characteristics of Mesoproterozoic and Neoproterozoic in the whole region by using seismic and logging data,and especially makes a reasonable prediction to controversial sea area.
