Well-documented tectonic events in the central Appalachians of Pennsylvania are: (1) the early Paleozoic Taconian orogeny that occurred during convergence of Laurentian and the Chopawamsic-Wilmington complex magmatic arc over an east-dipping subduction zone, and resulted in intense metamorphism and deformation in the Piedmont, and (2) the late Paleozoic Alleghanian orogeny that resulted in the thrust and fold belt in the Valley and Ridge province and dextral shear zones in the Piedmont. Unlike the Paleozoic tectonic history for the northern and southern Appalachians, the north-central part of the orogen in Pennsylvania lacks evidence for Acadian deformation and metamorphism. The relative chronological order of deformation and metamorphic events in the eastern Piedmont of Pennsylvania, combined with published geochro-nology suggests the previously undocumented Acadian deformation possibly exists as a transcurrent conjugate shear zone pair.
The Pan European Reserves and Resources Reporting Committee (PERC) Code for Reporting of Exploration Results, Mineral Resources and Mineral Reserves (further referred to as ‘the Code’) sets out minimum standards, recommendations and guidelines for Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves in the United Kingdom, Ireland and Europe. The history of development of this code is summarised in Appendix 4. This 2008 edition supersedes all previous editions of The Reporting Code and the IMM Reporting Code. <...>
The proceedings of the first International Conference on Trilobites and their Relatives held in Oslo in 1973 (Bruton 2019) were published in one of the earliest editions of Fossils and Strata (Martinsson 1975). It is highly fitting, therefore, that with the return of the conference to Baltoscandia (P€arnaste 2018), the Lethaia Foundation, under whose auspices Fossils and Strata is published, kindly offered to publish a volume of papers arising from the sixth meeting held in Tallinn, Estonia, in July 2017. The papers in the volume vary considerably in length. Although a notional page limit was given, it was made clear from the outset that there was some flexibility in this.
This volume is dedicated to Kenneth Jingwah Hsfi, Professor emeritus of the Swiss Federal Institute of Technology (ETH-Zfirich). It collects the proceedings of the Symposium on "Paradoxes in Modern Geology", held in Beijing on the 13th and 14th September 1999, to honour his 70th birthday.
The Pan European Reserves and Resources Reporting Committee (PERC) Standard for Reporting of Exploration Results, Mineral Resources and Mineral Reserves (further referred to as the 'PERC Reporting Standard') sets out the minimum standards, additional guidelines and recommendations for the Public Reporting of Exploration Results (including Exploration Targets), Mineral Resources and Mineral Reserves.
Results of theoretical analysis and experimental investigations for transport in porous media are presented. A new approach to modelling of transport in porous media is developed and a number of new percolation models is considered. The models allow to obtain analytical correlations for relative phase permeabilities for different porous media. Different methods of intensification of economic minerals based on new physical effects of reconstruction of the rock's pore space structure, are analysed.
The monograph is of interest for reservoir and chemical engineers, for specialists in reservoir characterization and simulation, for core analysts and researchers, and for post-graduate students in the above-mentioned areas.
В неглубоких водоемах пермского периода привольно себя чувствовали дискозавриски - интересные существа, сочетавшие в своем строении признаки амфибий и рептилий. По современной систематике (Иванов, Черепанов, 2004) дискозавриски относятся к отряду антракозавров, подклассу батрахозавров («лягушкоящеров»), классу амфибий. Охотились дискозавриски, по всей видимости, на мелких личинок насекомых, различных водных беспозвоночных и рыбок. Ископаемые остатки представителей семейства дискозаврисцид найдены и в Приуралье, в Оренбургской области и в Куединском районе Пермского края, в местонахождении Куединекие Ключики. <...>
