Compared with the Longmaxi Formation, the Niutitang Formation\n displays greater TOC (total organic carbon) content, depositional thickness and distribution area, but the details remain undetermined. In the study area, the Lower Cambrian Niutitang Formation typically has high TOC content, maturity and brittle mineral content. The study area has experienced\n multiple periods of tectonic movement, which have great influence on the fracture and pore characteristics. The fractures are mainly structural fractures and have obvious zoning. The primary types of pores are intraparticle pores, organic matter pores, and interparticle pores. Further, macropores\n and mesopores less than 50 nm contribute most of the pore volume, while pores less than 2 nm contribute most of the specific surface area. Many factors affect the pore-fracture system, such as tectonism, TOC content, mineral composition, and sedimentary environment. Tectonic movements produce\n fractures based on the changing stress field, but the degree of fracture development does not agree well with the degree of pore development. The TOC content has good positive correlations with the development of fractures and micropores, especially for nanoporosity, while clay minerals show\n a negative correlation with the development of fractures but a strong positive correlation with the growth of micropores. Quartz displays a positive correlation with the development of fractures but no good correlation with pore development. Finally, the lithofacies, lithologies and mineral\n compositions under the control of sedimentary environments are internal factors that can impact the development of pore-fracture systems.<\/jats:p>","DOI":"10.1166\/jnn.2021.18461","type":"journal-article","created":{"date-parts":[[2020,11,20]],"date-time":"2020-11-20T04:54:29Z","timestamp":1605848069000},"page":"57-71","source":"Crossref","is-referenced-by-count":3,"title":["Analysis
