Abstract

Abstract

The Dangba pegmatite-type spodumene deposit, located in the southeast of Keeryin orefield, also in the eastern part of Songpan-Ganze rare metal ore-forming belt, is one of super-large spodumene deposits in Sichuan, China. In order to find out the ore-forming potential in the deep and periphery, combining with the previous research results and field geological observation, this paper summarizes the spatial variation characteristics of magmatic rock facies and the mechanical characteristics of rock controlling structures in mining area, deeply analyzes the metallogenic regularity, and proposed the direction of geological prospecting. It is concluded as follows:(1) The main vein Ⅷ in Dangba mining area is albite spodumene+lepidolite type pegmatite vein formed by two-stage mineralization of superposition and recombination. The pegmatite intrastructural zoning is obvious in each period, with the lepidolite albite pegmatite belt, the muscovite albite pegmatite belt, and the spodumene albite pegmatite zone distributed from the outside to the inside; (2) Being controlled by the NW-trending and NEE-trending structures, the mineralized pegmatite belts show a trend of "X" type distribution; (3) Being centered around the diagenetic mineralization, vein Ⅵ NW extensional veins pitch to southeast, and the NE extensional veins pitch to northeast. This study indicates the direction of the deep and peripheral geological prospecting for Dangba spodumene deposit.
