摘要
In this paper, the tectonic background of formation and the characters of the two important unconformity interface and two kinds of faults in Luzong volcanic basin are analyzed. The deformation characteristics of the two stage overlapping-folds and the stratigraphic sequence and spatially distributing feature in Indosinian folding basement in Luzong volcanic basin and adjacent areas are discussed. And this paper introduced the expression and controversy of Jinzi Movement and Nanxiang Movement in Indosinian in the areas. Through the reunderstanding of metallogenic background, the mineralizing characteristics and prospecting direction of the three types deposits are summarized(volcanic-related iron deposits, neutral-acid intrusive rocks-related porphyry copper and lead-zinc deposits, contact metasomatic type and stratabound iron type of the iron and copper deposits). The paper emphasized the Yanshanic structural especially faulted structure control on magma intrusion and volcanic action and related mineralization. And the paper discussed the rock-controlling and ore-controlling structure conditions of typical deposits.
