Germanium isocontent map (Geochemical Atlas of Spain, 2012)

Iso-content maps of Germanium (Ge), 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.本数据集收录化学元素锗（Germanium, Ge）的等值含量分布图，数据源自西班牙地球化学图集（Geochemical Atlas of Spain Project）项目。采样介质涵盖河流沉积物（14864件样品）、表层土壤（0~20cm，13505件样品）与深层土壤（20~40cm，7682件样品）。化学分析包含两种类型：采用四酸法完成样品全消解，以及采用王水（aqua regia）进行部分消解。研究团队利用所有采样点的分析结果，通过反距离平方插值法，生成分辨率为1000m×1000m的方形网格等值含量图。最终成果为针对每类样品介质与每类分析方式的成套分布图集。
