火山作用对成岩成矿的意义,已为广大地质工作者所公认.三十年来,我国在火山岩地区开展地质调查、找矿勘探及科学研究工作,相继发现了一系列大、中、小型矿床,积累了丰富的实际资科和工作经验,提出了不少新观点和新认识.随着火山岩地区生产科研工作的进展,要求进一步加强区域火山岩资料综合对比,发展我国火山作用理论,促进火山岩地区区域地质调查和找矿.鉴于火山岩的复杂性,分类命名很不统一,岩石名称运用混乱,给综合研究对比工作带来许多困难,因此,逐步统一火山岩分类命名是当前急待解决的的问题.为此,中国地质学会岩石专业委员会于1980年11月10～16日在杭州召开了第一届全国火山岩会议.会议的中心议题是火山岩的分类命名,同时兼顾 The significance of volcanism for diagenesis and mineralization has been recognized by the majority of geological workers.30 years ago, China conducted geological surveys, prospecting and scientific research work in volcanic rock areas, and successively discovered a series of large, medium and small deposits, Accumulated a wealth of practical resources and work experience, put forward many new ideas and new understanding.With the progress of production and research work in volcanic areas, it is required to further strengthen the comprehensive comparison of regional volcanic data, the development of the theory of volcanic activity in our country to promote volcanic areas Geological survey and prospecting.Due to the complexity of volcanic rocks, the classification and naming are not uniform and the use of rock names is disorder, which brings many difficulties to the comprehensive research and comparison work. Therefore, the gradual unification of volcanic classification and naming is the urgent problem to be solved. As a result, the Geotechnical Society of China Committee of Rocks held its first national volcanic conference in Hangzhou from November 10 to November 1980. The central topic of the conference was the classification of volcanic rocks, taking into consideration
