Geochemical background of Berezovsky depression oil and gas potential (eastern Siberia)

Georesursy
Berezovsky depression, located on the northeast of the Pre-Patom foredeep, is a promising target for hydrocarbon prospecting, as evidenced by oil and gas shows established while drilling, the presence of structures and natural reservoirs.

Early eukaryotic microfossils of the late Palaeoproterozoic Limbunya Group, Birrindudu Basin, northern Australia

Papers in Palaeontology, Volume 9, Issue 6, November/December 2023., 2023
Abstract Fine‐grained, siliciclastic units of the >1642 ± 3.9 Ma late Palaeoproterozoic Limbunya Group, Birrindudu Basin host rich, well‐preserved organic‐walled microfossil assemblages that include members of total‐group eukaryotes. These assemblages include taxa characteristic of this interval such as Tappania plana and Satka favosa, as well as less ...

The role of siliciclastics in carbonate fabric diversity and preservation: A case study from the Neoproterozoic carbonate − siliciclastic Horse Thief Springs Formation, Death Valley

Sedimentology, Volume 69, Issue 5, Page 2284-2318, August 2022., 2022
Abstract The sedimentary record of the Pahrump Group in Death Valley comprises well‐exposed successions of mixed carbonate and siliciclastic deposits. Despite the abundance of studies focussing on the depositional dynamics of mixed carbonate – siliciclastic deposition in the Phanerozoic, the record of similar Proterozoic examples is comparatively ...

Constraints on the origins of iron silicide spherules in ultrahigh‐temperature distal impact ejecta

Meteoritics &Planetary Science, Volume 56, Issue 7, Page 1369-1405, July 2021., 2021
Abstract Terrestrially occurring iron silicide spherules, described in the geological literature for 160 years as cosmogenic and approved as “extraterrestrial” minerals by IMA CNMMN in 1984, so far have escaped any serious examination by meteoriticists.

GEODYNAMIC ASPECTS IN THE STUDY OF COMPLEX MINING AND GEOLOGICAL CONDITIONS FOR DRILLING INTO OIL-AND-GAS RESERVOIRS IN THE RIPHEAN CARBONATE ROCKS: AN OVERVIEW OF THE PROBLEM AS EXEMPLIFIED BY THE DEPOSITS IN THE BAIKIT PETROLIFEROUS DISTRICT

Геодинамика и тектонофизика, 2017
The practical aspects are discussed in the geodynamic studies of the massive vugular-fractured oil-and-gas reservoir in the Riphean carbonate rocks of the Yurubcheno-Tokhoma oil-gas-condensate field in the Baikit petroli­ferous district.

A Cryptic Alternative for the Evolution of Hyphae

BioEssays, Volume 42, Issue 6, June 2020., 2020
The current view that hyphae evolved about 400 million years ago when plants and fungi colonized land is challenged. Recent recognition of a deep biosphere fossil record provides an alternative view on hyphae: one where the fundamental functions of hyphae developed in ancient cryptic habitats and already where adapted for a terrestrial life‐style when ...

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]

, 2001
The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

Reconstruction of the conditions for the formation of red-colored sandstones of the Tersky coast based on a comparative analysis of the structure of ancient and modern deposits (Kola Peninsula)

Vestnik MGTU, 2023
The paper presents the results of studying the Riphean red-colored sandstones of the Tersky coast of the White Sea. 21 structural elements characterizing the conditions of rock formation have been considered, including 15 ancient and 6 modern deposits ...
