Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...

收集了鄂尔多斯地块西缘的21个宁夏区域地震台网台站和183个中国地震科学探测台阵台站记录到的2015年1月至2016年1月期间的远震P波资料,通过对其进行反褶积提取接收函数,并利用H-Kappa叠加方法计算了研究区内的莫霍面深度和泊松比。结果表明:研究区的莫霍面深度在36—58 km范围内变化,大体呈南厚北薄、西厚东薄的特点,且具有明显的分区特征,即以香山—天景山断裂为界,莫霍面在南北向呈现明显的起伏变化,该断裂以南的地壳增厚方式可能与青藏高原的水平挤压力所导致的上地壳重叠有关 ...

Geochemistry and tectonic development of Cenozoic magmatism in the Carpathian–Pannonian region [PDF]
This review considers the magmatic processes in the Carpathian–Pannonian Region (CPR) from Early Miocene to Recent times, as well as the contemporaneous magmatism at its southern boundary in the Dinaride and Balkans regions.

ABSTRACT The Roman city of Doclea is a key archaeological site of Montenegro, valued for its impressive remains and its role in the nation's cultural identity within European and the Mediterranean history. Doclea was the second‐largest city in the province of Roman Dalmatia, a municipium created in the first century ad and named after the Illyrian ...

Spatial reconstruction of tectonic stresses within the Subpolar Ural quartz crystal-containing province was conducted by the kinematic method [Gushchenko, 1973, 1979] based on the main indicators of tectonic stresses on slickensides. Local stress states (

The absence of women's scientific contributions in core UK pre‐university science qualifications
Abstract Despite their groundbreaking contributions to our understanding of the natural world and the universe, women's roles in biology, chemistry, physics, astronomy, environmental science and geology remain largely absent from standard educational specifications in the United Kingdom (UK), particularly at Key Stage 4 (KS4) and Key Stage 5 (KS5), or ...

Cenozoic Plate Tectonic Reconstructions and Plate Boundary Processes in the Southwest Pacific [PDF]
The Australia-Pacific-Antarctic plate circuit has long been a weak link in global plate reconstruction models for Cenozoic time. The time period spanning chron 20 to chron 7 (43-25 Ma) is particularly problematic for global plate models because seafloor

ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.
