Beryllium isocontent map (Geochemical Atlas of Spain, 2012)

Iso-content maps of Beryllium (Be), one of the chemical elements.obtained in the Geochemical Atlas of Spain Project, distributed in stream sediments (14,864 samples), superficial soils (0-20 cm.) (13,505 samples) and deeper soils (20-40 cm.) (7,682 samples). The results of the chemical analysis are shown in two types: total dissolution of the sample with 4 acids and partial dissolution with aqua regia. With the analytical results of all the sampled points, an isocontent map is made with adjustment to a square grid of 1,000 m by the method of interpolation of the inverse of the squared distance. The final result is a map for each type of sample and type of analysis carried out.本数据集包含化学元素铍（Beryllium，Be）的等含量分布图（iso-content maps），数据依托西班牙地球化学图集项目生成。采样介质涵盖河流沉积物（14864件样品）、表层土壤（0~20厘米，13505件样品）及深层土壤（20~40厘米，7682件样品）。化学分析设置两类方案：采用四酸消解法完成样品全消解，以及采用王水进行部分消解。基于所有采样点的分析结果，通过平方反比距离插值法，生成适配1000米×1000米方形网格的等含量分布图。最终成果为针对每类采样介质与每类分析方法的专属等含量分布图。
