摘　　要：海南岛新生代火山岩分布面积广、规模大,在热带条件下形成了风化型矿产资源。褐铁矿、铝土矿、钴土矿等是该区域火山岩风化形成的主要矿种,这些矿种在成矿上受岩性和地形地貌等控制,具有资源丰富、储量大、低品位共(伴)生等特色,在分布上以东西向的王五—文教断裂带为界,北部以褐铁矿为主伴生钴等元素,南部以铝土矿、钴土矿为主常伴生稀土、镓等元素。该区域风化型矿产资源由于受采矿、选矿等因素的限制,大部分尚未得到开发利用,但成矿资源量大、共伴生多种成矿元素、综合利用价值大,在资源开发利用时应予以重视。The Cenozoic volcanic rocks in Hainan Island show a wide distribution and a large scale,forming weathering mineral resources under tropical conditions.Limonite,bauxite and cobalt ore are the main minerals resulting from the weathering of volcanic rocks in the region.These minerals influenced by lithology,topography,and geomorphology,exhibit characteristics such as abundant resources,large reserves,and low-grade co-occurrence.Their distribution is bounded by the east-west Wangwu-Wenjiao fault zone,and primary ore in the north is limonite and associated cobalt,while primary ore in the north is bauxite and cobalt ore and associated gallium and rare earth element.Due to limitations in mining,mineral processing,and other factors,most of the weathered mineral resources remain undeveloped.Nonetheless,these resources possess significant ore-forming potential,are associated with various ore-forming elements,and hold considerable comprehensive utilization value,warranting attention in resource development and utilization.
