Journal: :Proceedings of the Yorkshire Geological Society 2022

Here, we describe the upper Pliensbachian to middle Toarcian stratigraphy of Dove's Nest borehole, which was drilled near Whitby, North Yorkshire, in 2013. The core represents a single, continuous vertical section through unweathered, immature Lower Jurassic sedimentary rocks. thickness Lias Group formations is approximately same as that exposed along Yorkshire coast between Hawsker Bottoms and...

The paleoenvironmental impact of the early Aptian Ocean Anoxic Event 1a (OAE 1a, ca. 121 Ma) has been investigated in detail Cismon Core (Lombardy Basin, western Tethys) by using different geochemical and micropaleontological proxies. We provide first high-resolution data benthic foraminiferal assemblages through upper Barremian - lower stratigraphic interval. Benthic foraminifera are integrate...

Introduction: Effective perception of fear signals is crucial for organism survival. When threated, the organism indicates defensive behaviors. Methods: Elevated plus–maze has high efficiency for measurement of fear behavior and is widly used for fear behavior determination. Increase in two parameters percent of openarm entries (%OAE) and percent of time spent in the open-arm (%OAT) in the ...

Introduction: In this study, we investigated the role of N-Methyl-D-Aspartate (NMDA) receptors in the ventral hippocampus (VH) and their possible interactions with GABAA system on anxiety-like behaviors. Methods: We used an elevated-plus maze test (EPM) to assess anxiety-like behaviors and locomotor activity in male Wistar rats. Results: The results showed that intra-VH infusions of diffe...

Some of the major Carbon cycle perturbations Phanerozoic occurred during Aptian, in relation to magmatism. The highest temperatures reconstructed for Cretaceous Period correspond Oceanic Anoxic Event early Aptian (OAE 1a), an episode accelerated global change. Here we present a chemostratigraphic study based on osmium isotopes integrated with high-resolution Carbon-Oxygen stable isotope data fr...

Background: Loss of hearing is a non-visible disability (NVD) and the second most common congenital pathology. Apart from hearing loss, further disability in these domains has been reported like development of language, speech, cognition, and other evolving domains. These can be prevented by early identification and intervention. The aim of this study was to assess the outcomes of neonatal hear...

سازند کژدمی (اواخر آپتین پیشین – آلبین میانی) یکی از سازند های شیلی مارنی است، که در زون ساختاری زاگرس در جنوب و جنوب غرب ایران قرار گرفته و این سازند بواسطه پتانسیل سنگ منشا بودن مخازن نفت وگاز سازند آسماری در اکثر میادین نفتی، یکی از مهم ترین سازند های زاگرس است. به منظور مطالعات زیست چینه ای و تعیین سن دقیق سازند کژدمی بر اساس فرامینیفرهای پلانکتونیک و تطابق بایوزون های شناسایی شده با بایوزو...
