BIOSTRATIGRAPHIC ANALYSIS OF THE OLIGOCENE-EARLY MIOCENE SUCCESSIONS FROM SULAIMANI AREA, KURDISTAN REGION, IRAQ

open access: yesIraqi Geological Journal, 2020
Three sections (Darzila, Hazar Kani and Basara) of the Oligocene –Early Miocene successions from Sulaimani area, Kurdistan region-NE Iraq, were measured and studied in order to interpret the biostratigraphic zonations at the Low and High Folded Thrust ...

A possible Late Oligocene–Early Miocene rocky shoreline on Otago Schist

open access: yesNew Zealand Journal of Geology and Geophysics, 2013
Duntroonian–Waitakian limestone at Kokonga in the Maniototo district, Central Otago, New Zealand is interpreted to be a rocky shoreline facies formed near the time of maximum Cenozoic marine transgression across Zealandia. The limestone, which is correlated with the Otekaike Limestone of North Otago, contains shallow and warm water indicators such as ...

Microfacies Analysis and Diagenetic Assessment of the Late Oligocene-Early Miocene Succession in Khabaz Oilfield, Northern Iraq

open access: yesThe Iraqi Geological Journal, 2022
The Jeribe and Azkand formations, which were deposited during Late Oligocene-Early Miocene are a major reservoir interval in the Khabaz oilfield where it is, for the most part, a carbonate reservoir. The study area is located in the north of Iraq within the Foothill Zone. Through the thin-section examination for Azkand/Anah carbonates in the Khabaz oil

Oligocene-miocene mammalian fossils from Hongyazi Basin and its bearing on tectonics of Danghe Nanshan in northern Tibetan plateau. [PDF]

open access: yesPLoS ONE, 2013
A shortage of Cenozoic vertebrate fossils in the Tibetan Plateau has been an obstacle in our understanding of biological evolution in response to changes in tectonism, topography, and environment.
