论文摘要
这项调查介绍了北大西洋下佛罗里达州迈阿密沿岸的拟议撞击火山口的发现。对从国家海洋和大气给药获得的测深数据进行的初步分析暗示，与外星外生物的超速影响事件产生的复杂火山口相符。所提出的冲击特征包括中央峰，同心环和西北的弹出场。对美国地质调查局的地质数据的分析将拟议的影响地点上覆盖为迈阿密石灰石，更新世，在海洋同位素阶段5e期间积累，从而将拟议的撞击火山口的最大年龄置于80 ka至130 ka。在整个研究过程中探索了其他三个用于形成结构的竞争假设，即在整个研究过程中探索了结构的形成，即火山的受控海事爆炸，径向熔岩流，或者是抑郁的生物处理，多琳或喀斯特（溶液抑郁症）。为了确认拟议的结构为撞击火山口，Planetary Sciences，Inc。组织了原位的水下探险。专门确定是否存在平面形成，破碎的锥和冲击变质和或其他陨石特性。在分析了提议的冲击火山口收集的地质样本，检查类似地质结构的形态并评估竞争假设的形态后，我们得出结论，该结构是一种解决方案多琳，该解决方案是由迈阿密石灰石的不均匀溶解形成的，并且不建议在地球中索引地球酶在地球上索引，这是一个解决方案。
This investigation addresses the discovery of a proposed impact crater located off the coast of Miami, FL under the North Atlantic Ocean. A preliminary analysis of bathymetry data obtained from the National Oceanic and Atmospheric Administration implied a morphology consistent with a complex crater produced by a hypervelocity impact event of extraterrestrial origin. The proposed impact features include a central peak, concentric rings, and an ejecta field to the northwest. Analysis of geological data from the US Geological Survey places the strata overlying the proposed impact site as Miami Limestone, Pleistocene, accumulated during Marine Isotope Stage 5e, thereby placing the maximum age of the proposed impact crater at 80 ka to 130 ka. Three other competing hypotheses for the formation of the structure, namely a controlled maritime explosion, radial lava flow from volcano, or a depressed bioherm, doline, or karst (solutional depression) were explored throughout the investigation. To confirm the proposed structure as an impact crater, an in-situ underwater expedition was organized by Planetary Sciences, Inc. specifically to ascertain whether planar formations, shatter cones, and shock metamorphic and or other meteoritic properties were present. After analyzing the geological samples collected at the proposed impact crater, examining the morphology of analogous geologic structures, and evaluating competing hypotheses, we conclude that the structure is a solutional doline formed by the uneven dissolution of the Miami Limestone, and, accordingly, do not recommend that the structure be indexed in the Earth Impact Database
