THE N.A. GOLOVKINSKY’S FUNDAMENTAL FACIAL LAW — PROBLEMATICS AND NEW HORIZONS

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2018
Famous Russian geologist N.A. Golovkinsky published 150 years ago an important scientific work, where the phenomenon of lateral  displacement (movement) of homogeneous lithological layers  («slide» over time) was asserted.

Influencing Factors on Petrography Interpretations in Provenance Research—A Case-Study Review

open access: yesGeosciences, 2021
The use of framework petrography is a common initial step in provenance research of sand and sandstone. The data tend to be interpreted based on the three main components quartz, feldspar, and lithic fragments.

Age, facies, and geometry of the Sandbian/Katian (Upper Ordovician) pelmatozoan-bryozoan-receptaculitid reefs of the Vasalemma Formation, northern Estonia

open access: yes, 2014
The Vasalemma Formation (early Katian, Late Ordovician) of northern Estonia consists of a succession of biodetrital grainstones up to 15 m thick with numerous intercalated reef bodies, which reach diameters of more than 50 m.

Facies and sequence stratigraphic implications of the Statfjord formation (upper triassic-lower Jurassic), northern north sea, UK [PDF]

open access: yes, 1996
Detailed sedimentological logging of core, and interpretation of wireline logs from the Brent Oil Field, northern North Sea, have allowed for the identification of sedimentary facies and environments of the Upper Triassic-Lower Jurassic Statfjord ...

Carbonate facies, diagenesis and sequence stratigraphy of an eocene nummulitic seservoir interval (jdeir formation), offshore NW Libya [PDF]

open access: yes, 2006
This study investigates the sedimentology, petrology and depositional environments of a major Early Eocene nummulitic reservoir unit: the Jdeir Formation, from offshore NW Libya in the Mediterranean Sea. This formation is a prolific hydrocarbon-producing

Ramp reef depositional facies model for the Mid-Pliocene Golden Gates Reef Member of the Tamiami Formation, South Florida

open access: yes, 2019
The depositional setting for northern most Atlantic coral reef development during the Mid-Pliocene Warm Period is a gentle sloping mixed carbonate–siliciclastic ramp.

SEDIMENTOLOGICAL STUDY OF THE HARTHA & SAADI FORMATIONS FROM SELECTED WELLS IN QAYARA OIL FIELD NORTHERN IRAQ [PDF]

open access: yesKirkuk Journal of Science, 2015
The research included sedimentological study of Hartha and Saadi formations in Qayara oil fields: (QY53, QY84, QY82, QY54). The study indicates that the rocks of both formations are composed from limestone, dolomitic limestone, and dolomite which are ...
