福建永定山口早侏罗世火山喷发-沉积型钼矿床地质特征

Geological Characteristics of the Shankou Molybdenum Deposit of Lower Jurassic Volcanic Eruption and Sediment type in Yongding County of Fujian Province

通过对福建永定山口钼矿床地质特征的初步总结,认为永定山口钼矿床主要产于早侏罗世藩坑组中段,矿体受地层岩性控制,呈层状、似层状分布,成矿作用与火山喷发-沉积关系密切,属早侏罗世火山喷发-沉积型钼矿床。

The geologic characteristics of the Shankou molybdenum deposit in Yongding County are under discussion in the paper. It is considered that the molybdenum deposit mainly lays in the intermediate section of Lower Jurassic Fangkeng Formation and the ore bodies are controlled by the stratum lighology, which are distributed as a layered or quasi-layered form. The ore forming process has a close relation of volcanic eruption, Therefore, it belongs to the molybdenum deposit of the Lower Jurassic eruption-sediment type.
