在赣中丰城地区出露一套厚达数千米的晚元古界神山群偏碱性的细碧岩、细碧质角砾熔岩,与上覆震虫系下统类复理石沉积变质岩夹基性火山岩呈渐变关系。
5) breccia pipe
角砾岩筒
1.
Based on the research of ore-controlling laws in Hulalin gold deposit in Inner Mongolia,the authors consider that dominate disseminated mineralization was absolutely controlled by a breccia pipe.
通过对虎拉林金矿构造控矿规律研究,认为矿区占绝对优势的浸染状矿化主要受角砾岩筒构造控制,矿化不均匀,矿体形态不规则;通过分析该角砾岩筒内角砾岩的特点,结合一般浅成、半浅成角砾岩筒的垂向分带规律,推测该角砾岩筒已剥蚀到了中下部。

The Yantang CuMo deposit is located in a breccia pipe of northeast Wuzhishan uplift,Hainan Island.
琼海烟塘梅岭铜钼矿床位于海南五指山隆起东北侧的一个"角砾岩筒"中,该"角砾岩筒"的形成受南北向、东西向构造-岩浆岩带控制,与燕山期花岗闪长岩、花岗闪长斑岩关系密切。

角砾岩
1.
Fractal statistical computation is given to the breccias associated with the ore body II,typical ore body in the Fenghuangshan deposit.
通过对凤凰山铜矿II号矿体不同地段的角砾岩进行分形统计分析,判明其属于液压致裂角砾岩,验证了分维值的大小与致裂能量之间的正相关关系。
补充资料:细碧岩
细碧岩 spilite 一种基性熔岩。灰绿色,常具间粒结构、辉绿结构、凝灰结构和枕状构造。矿物成分复杂,变化大。斑晶矿物主要为钠长石和辉石,基质由绿泥石、阳起石、方解石、绿帘石、葡萄石、石髓等组成。常与角斑岩、石英角斑岩一起组成海底火山喷出岩系。水化和碳酸盐化普遍。一般不含橄榄石或已变成蛇纹石假象。常伴有黄铁矿和黄铜矿的富集层。通常认为它是地槽早期海相火山作用的产物,有些学者认为,它不一定是原生的,也不一定出现在地槽区,而是在水的参与下形成的变质基性火山岩,或是变了质的玄武岩。 |
