摘要
通过系统的地质勘查,深化了海南罗葵洞钼矿赋矿围岩的认识。认为赋矿岩系为四层火山岩岩石组合,它们从上而下分别为:流纹质碎斑熔岩夹流纹质角砾熔岩,安山岩夹安山质角砾熔岩,流纹质角砾熔岩、安山质碎斑熔岩、安山质角砾熔岩、安山岩互层,似斑状花岗岩及石英正长岩。赋矿围岩控制着钼矿的存在,因此通过对赋矿围岩的研究与认识,发现一处大型细脉浸染型钼矿床。
Through systematic geological prospecting, the surrounding rock of ore deposit around Luokuidong Molyb- denum Mine in Hainan was deeply known. The surrounding rock of ore deposit was consisted for four tectonic layers. From top to bottom, these layers include： rhyolitic porphyroclastic lava which sandwiched rhyolitic breccia lava; andesite which sandwiched andesite breccia lava; interbedding rock which was consisted of rhyolitic breccia lava and andesite porphyroclastic lava and andesite breccia lava and andesite; porphyraceous granite and quartz syenite. They controled the hosting of molybdenum mine and a large molybdenum mine of venial - disseminated was found by studing the characteristics of surrounding rock.
