| 中文摘要: |
| 重庆高燕锰矿锰矿石资源量(333)2448.2万t,平均品位为17.94%,为大型锰矿床。通过对重庆市城口高燕锰矿区深部钻探揭露的含矿层横、纵向变化特征综合研究,建立了沉积相模式。初步认为城口高燕锰矿现代沉积相为台沟相、深水盆地亚相(Ⅰ)、盆地斜坡亚相(Ⅱ)、浅水盆地亚相(Ⅲ)。锰矿沉积主要受水动力条件、盆地地形、海水深度及藻类的影响,锰矿主、次矿层的结构变化主要受沉积相控制。 |
| 英文摘要: |
| By studying the transverse and longitudinal variation characteristics of deep ore-bearing strata in Gaoyan manganese mine area, the author established sedimentary facies patterns,and initially thinks:the modern sedimentary facies of Chengkou Gaoyan manganese deposit is platformal trough facies, deep water basin subfacies (Ⅰ), the slope of the basin subfacies(Ⅱ), shallow water basin subfacies(Ⅲ), manganese ore deposits mainly is influenced by hydrodynamic conditions, basin landform, water depth and the algae, and the structural changes of the main and secondary layers of manganese ore are mainly controlled by sedimentary facies. |
