摘　　要：黔东新元古代"大塘坡式"锰矿由于储量规模大,品位高而受到专家学者的关注,道坨锰矿是锰矿整装勘查过程中新发现的超大型锰矿床,实现了贵州锰矿找矿40多年来最重大的突破。通过对道坨锰矿结构构造,矿体沉积特征的研究,发现道坨锰矿石物质组成复杂,具有热水沉积矿物组成特征,且发育热水与海水混合沉积的块状构造、条带构造、气泡构造,矿体的形态呈薄—厚—薄的"透镜体",具有热水沉积集中供源的特征。The large reserves of high grade of neoproterozoic ＂Datangpo type＂ manganese deposit in East guizhou that attract of experts. Daotuo manganese deposit is The super large mega manganese deposit found in the process of exploration. It is the most significant breakthrough of the manganese ore prospecting in guizhou more than 40 years. This article through to research the structure and sedimentary characteristics of the daotuo manganese ore. Found the manganese ore composition complex, has the characteristics of hot water sedimentary mineral composition. The block structure, banded structure, bubble structure has the hydrothermal and seawater mixed Characteristics. The morphology of the ore body whit thin-thick-thin ＂lens form＂, it has the characteristics of hydrothermal deposition for source concentrate.The authors analyzed Daotuo manganese deposit genetic model, Hope for the future of manganese deposit deep prospecting provide more basis.
