Tectonic control on the palaeogeographical evolution of the Miocene Seaway along the Western Alpine foreland basin

چکیده
Abstract The Miocene of the Western Alpine foreland basin were deposited in a north–south seaway along active alpine orogenic front. In subalpine massifs and southern Jura mountains, revised stratigraphy documents detailed chronology thrust propagation at western front, where tectonic activity had primary influence on palaeogeographical evolution. Here we propose nine maps during Miocene, first which depicts initial transgression c. 21.0 Ma. Between 18.05 12.0 Ma, westward retreat Sea occurred response to activation basal Belledonne massif, turn triggered successive fault zones from east west. At 10.0 major uplift phase intervened induced rapid southward Sea. reconstructed outline main controls evolution: (1) timing thrusts; (2) inherited palaeotopography; (3) eustatic sea-level changes Miocene. These reconstructions are integrated scale, highlighting southward- westward-directed migration that deeply shaped evolution early middle

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
