The Glossifungites Ichnofacies is a substrate‐controlled ichnofacies that occurs in omission surfaces and has been used in the identification and interpretation of stratigraphic discontinuities. The Early Permian Rio Bonito–Palermo sedimentary succession from the Paraná Basin (southern Brazil) offers an opportunity to discuss the genesis of the omission surfaces demarked by the occurrence of Glossifungites suites. These suites are composed of sharp, unlined burrows with irregular boundaries and passive infill by generally medium‐ to coarse‐grained sandstones. Thalassinoides is the dominant component in the Glossifungites suites in the studied deposits, with local occurrences of Diplocraterion, Gyrolithes, and Skolithos. Based on the ichnological signatures of the distinct Glossifungites suites observed in these deposits and the characteristics of the facies in which they occur, the associated discontinuity surfaces were interpreted as autogenic or allogenic. The morphological distinction between allogenic and autogenic expressions of the Glossifungites Ichnofacies is observed. Glossifungites suites demarking autogenic surfaces are associated with dewatered muddy substrates from the estuarine settings. Glossifungites suites demarking allogenic surfaces are characterized by large vertical burrows and occur in association with a sequence boundary and coplanar surfaces registered in lower shoreface settings.

巴西巴拉那盆地二叠纪河口和海岸沉积物中光泽真菌岩相的自生和异源表达差异

光泽真菌岩相是在遗漏面中发生的受基质控制的岩相，已用于识别和解释地层间断。来自巴拉那盆地（巴西南部）的早二叠纪里奥博尼图—巴勒莫沉积相继为讨论由闪锌矿岩组出现而形成的遗漏面的成因提供了机会。这些套件由尖锐的，无衬砌的洞穴组成，这些洞穴具有不规则的边界，并且通常由中等粒度到粗粒度的砂岩进行被动填充。Thalassinoides是所研究矿床中Glossifungites套件中的主要成分，局部存在Diplocraterion，陀螺和Skolithos。根据在这些矿床中观察到的独特的Gungfungites套件的岩石学特征以及它们出现的相的特征，将相关的不连续面解释为自生的或同种异体的。观察到了Glossifungites纤维相的同种异体和自体表达之间的形态学区别。标记有自生表面的光泽磷灰石套件与河口环境中的脱水泥质基质有关。标有同种异体表面的光泽磷灰石套件具有较大的垂直洞穴，并且与序列边界和在较低岸面环境中记录的共面表面有关。
