“爆发角砾岩是由于爆发作用而形成的火山角砾岩……”,这是爆发角砾岩最早的定义之一,是由于1893年提出的。由于爆发现象基本上具有火山活动的性质,所以从前人们把“爆发活动”概念与“火山活动”概念混为一谈。但是后来在勘探和开发不同建造类型的矿床时发现,爆发现象常常伴随有内生成矿作用。爆发角砾岩与铜铝矿床的关系最为人们熟知。虽然很早就知道这种岩石也在锡矿区发育,但因其分布不广,所以研究程度相当差。
“The breccia is a volcanic breccia that was formed as a result of the outburst ...” This was one of the earliest definitions of breccia that originated in 1893. Since the outbreak was basically volcanic, the concepts of “outbreak” and “volcanic activity” have been confused in the past. However, subsequent exploration and development of different types of deposits have found that eruptions are often accompanied by endogenic mineralization. The relationship between the breccias and Cu-Al deposits is most well known. Although it has long been known that such rocks are also developed in tin mines, their degree of research is rather poor because of their low distribution.
