Abstract: This dataset was established based on extensive collection of information on the results from various mineral explorations in the Wumengshan Region, Southwestern China. The data are presented in three sections:mineral deposit's basic information, mineral deposit geology, and dataset codes obtained by processing mineral deposits information of different mineral species as systematic classification, extraction, summarization and refining, and data quality inspection. The attribute data information on mineral deposit include mineral deposit's number and name, mineral species, location, latitude and longitude, genetic type of deposit, paragenetic deposit, associated deposit, deposit scale and formation age, etc.. The data represent exploration results from 2013 to 2016, covering 27 mineral species and 1, 834 mineral deposits. The data information on mineral deposit geology include mineral deposit's number, geotectonic location, litho-stratigraphic unit, intrusive rock, volcanic rock, metamorphic rock, geological structure feature and alteration of wall rock, etc. for 769 mineral deposits. The data information on dataset codes include mineral species, Level-Ⅲ and Level-Ⅳ metallogenic belts, genetic type of deposit, deposit scale, geological work level, and exploration intensity, etc.. This dataset contains abundant and credible data for a wide range of mineral species, providing important fundamental reference data for subsequent in-depth mineral resource evaluation, geological scientific research and mineral development deployment over the region.
