3D Visualization of geological structures using Python: the case study of the Palomeque sheets (SE, Spain)

The goal of this paper is the construction of computerized 3D visualization of geological structures. Several Python applications have been used to adapt the paper map-based geological classical information to numerical geological maps represented in HTML files. The models include a map with the stratigraphic and structural contacts and symbols, five serial vertical sections, and a geological block diagram, all with real topography. This block diagram made with 2D figures allows a 3D visualization. Palomeque area (Murcia region, southeastern Spain) has been used as a key-case. This area consists of a deformed Upper Cretaceous to Oligocene succession belonging to the Internal Zone Malaguide Complex. The main structure consists of two thrust-fold sheets forming an imbricate system, also affected by a set of strike-slip faults with a sinistral regime. The constructed maps show a good agreement with the published classical geological maps and cross-sections demonstrating the benefits of using these Python applications.The authors would like to acknowledge the Spanish Ministry of Science and Innovation Research Project PID2020-114381GB-100, semigrupos.ugr.es from University of Granada and Research Groups FQM-343 of the Junta de Andalucía, and Research Groups and Projects of the Generalitat Valenciana-University of Alicante, for financial support

A Python Application for Visualizing an Imbricate Thrust System: Palomeque Duplex (SE, Spain)

This paper introduces a Python application for visualizing an imbricate thrust system. The application uses the traditional geologic information to create an HTML geological map with real topography and a set of geological cross-sections with the essential structural and stratigraphic elements. On the basis of the high geological knowledge gained during the last three decades, the Palomeque sheets affecting the Cenozoic Malaguide succession in the Internal Betic Zone (SE Spain) were selected to show the application. In this area, a Malaguide Cretaceous to Lower Miocene succession is deformed as an imbricate thrust system, with two thrusts forming a duplex, affected later by a set of faults with a main strike-slip kinematic. The modeled elements match well with the design of the stratigraphic intervals and the structures reported in recent scientific publications. This proves the good performance of this Python application for visualizing the structural and stratigraphic architecture. This kind of application could be a crucial stage for future groundwater, mining, and civil engineering management.Research Project PID2020-114381GB-100 of the Spanish Ministry of Science and Innovation, Research Groups and Projects of the Generalitat Valenciana from University of Alicante (CTMA-IGA), semigrupos.ugr.es from University of Granada and Research Groups FQM-343 of the Junta de Andalucía

El bien también es banal: sobre "stille Helden" y literatura

An indeterminate number of people from the most diverse backgrounds collaborated to help hundreds of Jews escape their extermination. An inconvenience for post-war German society, it is not until the 1990s, with the beginning of a new context brought about by the new political environment, that we begin to see some attention paid to these people. Proof of such is found in the presence of this subject in scientific and informative literature as well as in commemorative literature and fiction. These persons are often referred to as stille Helden (Silent Heroes), a recognition they frequently reject as they do not consider their actions to have been the result of heroic intentions, rather the only possible reaction to what was happening around them. During a time of moral confusion, Good, for a few, was as banal as Evil for the great majority.Un número indeterminado de personas con los más diversos trasfondos colaboraron para que cientos de judíos pudieran escapar del exterminio. Incómodos para la sociedad alemana de posguerra, sólo a partir del inédito contexto propiciado por la nueva situación política se ha comenzado a prestar cierta atención a estas personas a partir de los años noventa. Prueba de ello es la presencia del tema tanto en la literatura científica o divulgativa como en la memorial o de ficción. Aquellos denominados comúnmente stille Helden rechazan a menudo esta consideración, pues su modo de actuar no se debió a intenciones heroicas, sino que era la única respuesta que a su modo de ver podían dar a lo que ocurría a su alrededor. En unos tiempos de confusión moral, el bien fue para ellos tan banal como el mal para la gran mayoría

Effect of particle shape and fragmentation on the response of particle dampers

A particle damper (PD) is a device that can attenuate mechanical vibrations thanks to the dissipative collisions between grains contained in a cavity attached to the vibrating structure. It has been recently suggested that, under working conditions in which the damping is optimal, the PD has a universal response in the sense that the specific dissipative properties of the grains cease to be important for the design of the device. We present evidence from simulations of PDs containing grains of different sizes, shapes and restitution coefficients, that the universal response is also valid when fragmentation of the grains occurs (generally due to intensive operation of the PD). In contrast, the welding of grains (caused by operation under high temperatures) can take the PD out of the universal response and deteriorate the attenuation. Interestingly, we observed that even at working conditions off the optimal damping, the shape of the grains remains unimportant for the response of the PD.Fil: Sánchez, Martín.

The Betic Neogene Basins (S. Spain)

The Betic Neogene basins first differentiated as small, interconnected marine passages, individualized as the major Betic reliefs were being uplifted and emerged as islands in the course of the Miocene during the Alpine Orogeny. Some of them were directly linked to the Atlantic Ocean and some others to the Mediterranean Sea. Narrows seaways, located at different positions and changing in time, marked the precise location of the Atlantic-Mediterranean connections. The geological history and the palaeogeographical evolution of the Mediterranean-linked basins are presented and discussed in this talk. A distinction is made between the “inner basins” (the most distant from the present-day Mediterranean Sea), and the “outer basins” (the nearest to the present-day Mediterranean Sea), exemplified by the Granada and the Sorbas basins respectively. A review of the main characteristics of their sedimentary infilling is given. Special attention is paid to key aspects such as a) evaporite deposition within these basins, its timing and its relation with the Mediterranean, late-Messinian desiccation; b) major climatic changes as deduced from the existence of alternating temperate (cool-water) and tropical (warm-water) shelf-carbonate deposits, and c) the reason for the abundance of huge microbial (stromatolite and thrombolite) domes at the end of the Miocene.Las Cuencas Béticas Neógenas corresponden originalmente a brazos de mar que se fueron individualizando conforme la Cordillera Bética se fue levantando en el curso del Mioceno en la Orogenia Alpina. De ellas unas abrían hacia el Océano Atlantico y otras hacia el Mar Mediterráneo. Estrechos, de posición variable a lo largo del tiempo, mantuvieron a su vez la conexión, a traves de ellas, entre estas dos grandes masas de agua. En esta charla se analiza la historia geólogica y evolución paleogeográfica de dichas cuencas en especial las de filiación Mediterránea. Se hace distinción entre las situadas mas hacia el interior y las localizadas mas próximas al Mediterráneo actual, y se utilizan como ejemplos tipo la cuenca de Granada y la de Sorbas respectivamente, de las que se detalla su relleno sedimentario. Se resaltan determinados aspectos de intéres tales como a) los depositos evaporíticos, su heterocronía y relación con la desecación del Mediterráneo en el Mioceno terminal; b) los grandes cambios climáticos contrastados por la existencia de episodios de sedimentación carbonatada de plataforma de carácter templado (aguas frías) y carácter tropical (aguas cálidas), y c) el porqué de la proliferación y el extraordinario tamaño de los domos microbianos (estromatolitos y trombolitos) del Mioceno terminal
