鸡东盆地古近系虎林组地层岩相古地理研究

Study on Lithofacies and Paleo Geography of The Hulin Formation in The Jidong Basin

鸡东盆地位于黑龙江省鸡西市。主要含煤地层为古近系虎林组,沉积环境多样。本次工作通过对不同沉积层序地层厚度、砂岩百分含量、泥岩百分含量、及砂泥比的统计分析,在砂泥比等值图上,参考地层厚度、泥岩百分含量等值线图,通过综合地质分析,恢复了古近系鸡东盆地的岩相古地理面貌,总结了古近系含煤岩系的古地理演化过程及特征,为鸡东盆地聚煤作用分析奠定了基础。

Jidong basin located, Jixi City, Heilongjiang Province. Mainly containing coal strata is Paleogene Hulin formation, diversity of sedimentary environment.This work through the analysis of the different sedimentary sequence stratigraphic thickness, percentage of sandstone and mudstone percentage content, and sand shale ratio statistics, in the mud and sand than the equivalent figure, reference formation thickness, shale percentage content isoline map, through the comprehensive geological analysis, restored the Paleogene Jidong basin of lithofacies paleogeography, summarizes the Paleogene containing coal strata of paleogeographic evolution process and characteris-tics, Jidong basin poly coal analysis laid the foundation.
