1) hydrothermally eruptive
热液喷发角砾岩
1.
The Yiarmand gold deposit occurs in hydrothermally eruptive breccia of the 2nd Member of Lower Carboniferous Dahalajunshan Formation and its underlying arsenopyritized and pyritized tuffaceous clastic rocks,and the ore forming process can be divided into hydrothermally eruptive and sedimentary stage and metasomatic stage.
伊尔曼德金矿床赋存于下石炭统大哈拉军山组第二岩性段硅化热液喷发角砾岩及其下伏上泥盆统吐呼拉苏组毒砂黄铁矿化凝灰质碎屑岩中,成矿作用可分为热液喷发沉积期和热液交代蚀变成矿期。
2) eruptive breccia
喷发角砾岩
3) hydro thermal breccia
热液角砾岩
1.
The ore-hosting sequence has been formed into hydro thermal breccia due to the thermal alteration and structural brecciation.
新疆伊宁县金山金矿床是一正在进行勘探的大型金矿,属于浅成低温热液型金矿,金山金矿床产于早石炭纪大哈拉军山组火山岩下部,容矿岩层受热液蚀变和构造角砾岩化作用形成了热液角砾岩。
4) hydrothermal explosion breccia
热液气爆角砾岩
5) Hydrothermal crypto-explosive breccia
热液隐爆角砾岩
6) effusive breccia
喷出角砾岩

分子式:
CAS号:
性质:简单撞击坑视坑底下伏一层较厚由回落角砾岩块、熔岩组成的透镜状沉积层,如Meteor、Brent、Lonar Lake、West Hawk Lake等简单撞击坑。通常上伏晚期湖相沉积物,下伏冲击压力15~20GPa的原生坑底单矿物碎屑角砾岩。整个撞击坑显示出地球物理场异常。这一沉积构造特征,可通过地球物理方法寻找被掩藏的撞击坑。
