浙江省中岙细碧岩类岩石学岩石化学特征及其成因

前人长期将中岙金矿体的围岩误定为陆相安山岩、蚀变安山岩、安山玢岩、熔结凝灰岩等。1982年至今我们在野外和室内对中岙金矿床的地层和岩石进行了系统地岩石学、岩石化学研究,对这套以细碧岩类为主体的古火山岩系进行了重新命名和分层。并提出了细碧岩的成因。我们认为这可能有利于阐明金矿脉的成因和找矿方向。

THE PETROLOGICAL AND PETROCHEMICAL CHARACTERISTICS OF SPILITIC ROCKS AND THEIR ORIGIN IN ZHONGAO , ZHEJIANG PROVINCE

So far the misidentificatiou based on previous work has been made on the country rocks of Zhong-ao gold ore body and they have been regarded as continental andesite, altered andesite, andesitic porphyrite and welded tuff, since 1982 we have made systematic and scientific researches on petrology and petrochemistry of these rocks and renamed these old igneous (predominantly spilite ) rocks. The stratigraphical reconstruction has been made, and the origin of spilite has been suggested as well, we expect that this paper will be useful for the research of the origin of the gold mineral deposits and direction of their searching.
