Ore-controlling factors and prospecting direction of the bauxite deposit in Yuecun Henan Province
The Yuecun bauxite deposit occurred in the paleo weathered erosion surface of ordovician carbonate rock,the ore-bearing horizon was the Benxi Group strata of Lower Carboniferous series.The mine was a large fireclay deposit.This is a research gap from ore-controlling factors and prospecting direction of bauxite,especially deep bauxite in this area.Summarize the previous research results and basic data of mining area.The study shows that Yuecun bauxite was formed under the comprehensive action of palaeotopography,palaeostructure,paleoclimate mineralization and other factors in a specific period.The prospecting criteria and methods are sum-marized.It was suggested that attention should be paid to the negative terrain areas such as karst rock pits or bucket controlled by microfacies in supratidal zone of the edge of ancient land(island)in the future prospecting.
