Abstract. Sediments provide valuable information for geologists and geophysicists whenever they strive to understand, and reproduce, the geological evolution, lithology, rock properties, seismic response, and geohazards of a region. The analysis of sedimentary sequences is thus useful to the interpretation of depositional environments, sea-level change, climate change, and to a recognition of the sediments' source areas, amongst other aspects. By integrating sedimentary data in geophysical modelling, such interpretations are improved in terms of their accuracy and reliability. To help our further understanding of Iberia's geological evolution, geological resources and geohazards, this work presents to the scientific community the SedDARE-IB data repository. This repository includes available data of the depth to the Base Cenozoic and Top Paleozoic stratigraphic markers for the Iberian Peninsula and surrounding Western Atlantic and Mediterranean Neogene basins, or to the acoustic basement as interpreted for the Valencia Trough and Alboran Mediterranean basins. As an example of the broad applicability of the data included in SedDARE-IB, we investigate how sediment thickness affects the depth to the 150 ^oC isotherm at specific basins, as commonly used in geothermal exploration. The calculated trend suggests that, given constant measured surface heat flow and thermal conductivity, the 150 ^oC isotherm becomes shallower as a function of sediment thickness, until a critical threshold value is reached for the latter.SedDARE-IB database has been built thanks to a Portuguese-Spanish collaboration promoting open data exchange among institutions and research groups. SedDARE-IB is freely available at https://doi.org/10.20350/digitalCSIC/16277 (Torne et al., 2024) bringing opportunities to the scientific, industrial, and educational communities for diverse applications.

SedDARE-IB：伊比利亚及其大陆边缘沉积物数据的开放获取存储库


摘要。每当地质学家和地球物理学家努力了解和再现一个地区的地质演化、岩性、岩石特性、地震响应和地质灾害时，沉积物都会为他们提供有价值的信息。因此，沉积序列的分析对于解释沉积环境、海平面变化、气候变化以及识别沉积物源区等方面很有用。通过将沉积数据整合到地球物理模型中，这种解释的准确性和可靠性得到了提高。为了帮助我们进一步了解伊比利亚的地质演化、地质资源和地质灾害，这项工作向科学界展示了 SedDARE-IB 数据存储库。该存储库包括伊比利亚半岛和周围西大西洋和​​地中海新近纪盆地的基底新生代和顶部古生代地层标记深度的可用数据，或巴伦西亚海槽和阿尔沃兰地中海盆地解释的声学基底的深度。作为 SedDARE-IB 中数据广泛适用性的一个例子，我们研究了沉积物厚度如何影响特定盆地 150 ^o C 等温线的深度，如地热勘探中常用的那样。计算的趋势表明，给定恒定的测量表面热流和导热率，150 ^o C 等温线随着沉积物厚度的变化而变浅，直到达到后者的临界阈值。SedDARE-IB该数据库的建立得益于葡萄牙与西班牙之间的合作，促进了机构和研究小组之间的开放数据交换。 SedDARE-IB 可在 https://doi.org/10.20350/digitalCSIC/16277 免费获取（Torne 等人，2017）。，2024）为科学、工业和教育界带来多种应用的机会。
