  "abstract": "<p>As a means of investigating the structure of the geological subsurface and delineating Sn-W-Li greisen-hosted&nbsp;mineral deposits in the Geyer-Ehrenfriedersdorf area, Central&nbsp;Erzgebirge, Germany, we collected an ambient noise dataset which was supplemented and analysed together with&nbsp;airborne time-domain&nbsp;electromagnetic data. The here presented dataset is a combined three-dimensional block model containing the following parameters:</p>\n\n<p>(X), (Y), (Z) &ndash; Coordinates of the block model center nodes in ETRS89 UTM33N coordinates.</p>\n\n<p>(PS_vel) &ndash; Shear wave velocity&nbsp;based on ambient noise data from a dense &quot;LARGE-N&quot; network comprising 400 low-power, short-period seismic stations tomographically inverted&nbsp;based on Bayesian statistics.</p>\n\n<p>(logVTEM_res) &ndash; Logarithm of resistivity based on airborne time-domain electromagnetic data acquired using the Geotech Versatile Time Domain (VTEM&trade; ET) system&nbsp;and inverted using a&nbsp;layered earth approach.</p>\n\n<p>(class_K-means) &ndash;&nbsp;Class labels of a spatially constrained clustering using&nbsp;K-means with 26 immediate neighbours&nbsp;performed on the bivariate velocity-resistivity 3D dataset.</p>",
