摘要
Abstract
The Longtian isolated carbonate platform is located in the hinterland of the Youjiang Basin.Three small gold deposits have been discovered within a 1km range along the platform margin,and the geological conditions for mineralization are superior.This article summarizes the geological characteristics and main controlling factors of the gold deposit on the margin of the Longtian Platform,and explores the source of ore-forming materials and ore-forming era of the gold deposit.Research has shown that gold deposits are mainly distributed within the secondary fault zone of the Longtian Huantai Fault,with the main source of ore-forming materials being the Triassic surrounding rock,and the ore-forming fluid mainly being atmospheric precipitation.The gold deposits were generally formed in the late Indosinian to early Yanshanian periods,during which the Youjiang Basin was in a tectonic transition period from collision compression to stretching.关键词
