| Stratotypical sections of the Upper Ordovician Khoreyver basin (Timan-Pechora region) | |
| Descriptions of stratotypic and hypostratotypic sections of the Upper Ordovician of the Khoreyver Basin are given. The stratotypes of the Malomakarikha, Bagan and Muker Formations were established in the section of the Zapadno-Makariha (Srednemakarikha) 16 well, their hypostratotypes - in the Srednemakarikha 22 well. The stratotype section of the Khoreyver Formation was described in the Khoreyver 1 well, the hypostratotype - in the Srednemakarikha 22 well. The stratotype section of the Salyuka Formation was selected in the section of the Salyuka 2 well, the hypostratotype - in the Sandivey 40 well. Keywords: Malomakarikha Formation, Bagan Formation, Muker Formation, Khoreyver Formation, Salyuka Formation, stratotype, hypostratotype, Upper Ordovician, Khoreyver depression, Timan-Pechora region. |

| Stratotypes of local stratigraphic units of the Lower Silurian of the Bolshezemelsk area (Timan-Pechora region) | |
| Descriptions of the local stratotypes of the Lower Silurian Formations of the Bolshezemelsk area of the Timan-Pechora region are provided and their geological and geophysical sections are presented. For the Makarikha Formation, the composite section of the parametric well Sandivey 31 and the exploratory well Sandivey 41 are proposed as the local stratotype. For the Sandivey Formation, the stratotype was established in the section of the well Sandivey 7, for the Veyak Formation, the composite stratotype was established in the parametric wells Zapadno-Veyak 1 and Severo-Salyukin 1. All wells are located in the territory of the Khoreyver depression, where commercial hydrocarbon accumulations are confined to the Lower Silurian strata. Keywords: local stratotype, Makarikha Formation, Sandivey Formation, Veyak Formation, Lower Silurian, Bolshezemelsk area, Timan-Pechora region. |
