Fig. 1: Simplified maps showing the distribution of Eocene to Oligocene potassic magmatic rocks in the Sanjiang region and the location of the investigated samples.
From: Ten kilometers ascent of porphyry Cu (Au, Mo)-forming fluids in the Sanjiang region, China
a, b The distribution of strongly mineralized felsic porphyries and weakly to non-mineralized variably evolved rocks in the Sanjiang region. The maps in (a) are modified after https://commons.wikimedia.org/wiki/File:Simplified_World_Map.svg and ref. 26, and the one in (b) after ref. 80. c The distribution of intermediate to felsic rocks in the Jianchuan area. The map is modified after refs. 81,82. d, e The distribution of strongly mineralized and weakly to non-mineralized felsic porphyries in the Beiya and Yulong areas. The maps are modified after refs. 29,30, respectively. The age ranges shown in (c) to (e) are based on in-situ zircon U-Pb dates of the intermediate to felsic rocks (see age summaries in refs. 16,29).
