泛第三极侏罗纪气候、岩相古地理图（195Ma、166Ma、150Ma）

采用板块构造、古地理学、含油气盆地分析和沉积盆地动力学理论作为指导，在大量收集泛第三极近年来地质研究和油气地质研究的各种资料成果，包括地层、沉积、古生物、古地理、古环境、古气候、构造、油气（钾盐）地质等基础材料，特别是以古地磁、古生物以及碎屑锆石、地球化学等资料的基础上，结合典型实测地层剖面的成果，对侏罗纪时期岩相和气候古地理格局进行恢复与重建，得到泛第三极早、中、晚侏罗世岩相古地理图（3张）及泛第三极早、中、晚侏罗世气候古地理图（3张），旨在探讨古地理、古构造、古气候等对油气（含钾盐）资源的控制和影响作用，以揭示油气形成的地质条件和资源分布规律，为我国海外和境内油气勘探部署提供科学依据和技术支撑。

Guided by theories of plate tectonics, paleogeography, petroleum basin analysis and sedimentary basin dynamics, this study collected a large number of research achievements in geological and petroleum geological studies of the Pan-Tertiary Pole region in recent years, including basic data such as stratigraphy, sedimentology, paleontology, paleogeography, paleoenvironment, paleoclimate, tectonics, petroleum (potash) geology, and especially data from paleomagnetism, paleontology, detrital zircon geochronology and geochemistry. Combined with the results of typical measured stratigraphic sections, we restored and reconstructed the lithofacies and climatic paleogeographic patterns during the Jurassic period, and obtained 3 lithofacies paleogeographic maps and 3 climatic paleogeographic maps for the Early, Middle and Late Jurassic of the Pan-Tertiary Pole region. This study aims to explore the control and influence of paleogeography, paleotectonics, paleoclimate and other factors on petroleum (including potash) resources, reveal the geological conditions for petroleum formation and the law of resource distribution, and provide scientific basis and technical support for oil and gas exploration deployment both overseas and domestically in China.
