Map of geological cross section is the most intuitive expression strata in vertical direction. Realizing automatic filling lithologic patterns and reflecting changes stratum curvature are important contents map drawing. The traditional pattern method can not show change rock dip angle. To solve this problem, an algorithm drawing based on arc fitting proposed. By analyzing mathematical relations...

The bedrock beneath the Tengger Desert is covered by Quaternary deposits, making it difficult to directly observe underlying geological information using traditional methods. In areas with limited prior information, employing geophysical methods obtain deep-seated constructing a multi-source dataset, and performing three-dimensional modeling can significantly enhance our understanding of underg...

Antecedent topography such as relic reef terraces well biogenic carbonate relief-forming deposits ~30–150 m deep, referred to mesophotic reefs, provide structural support for diverse coral ecosystems (MCEs) that may serve refuges select light-dependent species. Although at depths are found globally, an understanding of their spatial distribution, formation, and relationship with living communit...

Pantropical variation in soils of the tropical dry forest (TDF) biome is enormously high but has been poorly characterized. To quantify global distribution TDF soil physical and chemical properties relation to climate geology, we produced a synthesis using 7500 points data with gridded fields representing lithologic, edaphic, climatic characteristics. Our analyses reveal that 75 ecoregions acro...
