Mechanism Analysis of Organic Matter Enrichment of Upper Ordovician-Lower Silurian Shale in the Upper Yangtze Area: Taking Jiaoye-1 Well in the Jiaoshiba Block as an Example

<div>Mo content-TOC content of the Upper Ordovician Wufeng Formation-Lower Silurian Longmaxi Formation 1st member of the Jiaoye-1 well. (a) The upper section of the Longmaxi 1st member; (b) the Wufeng Formation-the lower section of the Longmaxi Formation. The base map is from Algeo and Lyons [<a href="/journals/geofluids/2019/5806023/#B68">68</a>] and Zhang et al. [<a href="/journals/geofluids/2019/5806023/#B30">30</a>].
