Examples
- There are a series of lead - zinc polymetallic deposits , such as fozichong , dongtao , xiashui , wenlongjing and jilongding distributed along the fault zone . these deposits have some similiar features : ? ll of them are bounded in the strata of lower palaeozoic group ; ? ain orebodies occur as stratiform or stratoid form with occurrence consistent with that of host strata ; ? tratiform skam or baritic rock are the direct country rock of orebodies ; ? ypical syngenetic sedimentary fabric preserved in the ore . these deposits may be included in the same metallogenic series
佛子冲、东桃、下水、文龙径、鸡笼顶等一系列铅锌多金属矿床沿该断裂带分布,这些矿床虽然在成矿规模、赋矿层位和矿石矿物组成等方面存在一些差异,但均产于下古生界地层中;主要矿体呈层状、似层状产出,与地层产状大体一致;直接赋矿围岩为层状绿色岩或重晶石岩;矿石中保留有典型的同生沉积组构。 - The fluids upwelled to seafloor along fault thus ore - forming metals accumulated . 2 . this paper indicated the definition the hydrothermal sedimentary rocks . the definition is a group of especial sedimentary rocks forming at the temperature ranging from 70 ? to 350 ?
