Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Deeply buried Devonian sediments of the eastern edge of Precaspian Basin are widely extended; Upper Devonian reef-like deposits can be identified according to seismic surveys and poorly characterized by core material. In the present study depositional environment, predominant biota and diagenetic characteristics of the KT-III carbonate formation are described in order to evaluate reservoir potential. The paper presents the results of determining the mineral composition, geochemical features, sedimentological (identification and description of microfacies) and diagenetic characteristics of the Upper Devonian carbonate sediments of the Urikhtau area (KT-III).
