| 中文摘要: |
| 松桃杨家湾大型锰矿床是典型的“大塘坡式”锰矿床。该矿床是在上世纪80年代103队松桃黑水溪锰矿床外围找矿预测的基础上，历经5年(2006—2011年)的勘查实践，提交锰矿资源储量逾2 000万吨，结束了黔东地区当时没有大型锰矿床的历史。在对该矿床的矿床特征和构造古地理等特征分析研究的基础上，认为杨家湾锰矿床位于南华纪大塘坡早期北东65°70°方向展布的黑水溪-杨家湾狭长带状的Ⅳ级地堑盆地中。结合该矿床矮河溪一带发现有被沥青充填的气泡状构造和渗漏管构造等古天然气渗漏沉积构造分布特征，该矿床的成因类型与松桃大塘坡锰矿床一样，属典型的古天然气渗漏沉积型锰矿床。 |
| 英文摘要: |
| Yangjiawan large manganese deposit is a typical “Datangpo” manganese deposit in Songtao.The deposit was based on the prospecting of the outskirts of the Songtao Heishuixi manganese deposit in the 1980s in the 1980s，after five years’ exploration practice(2006—2011)，more than 20 million tons of manganese ore reserves were submitted，end a history of no big scale manganese deposit in east Guizhou. Based on the analysis of the characteristics of the deposit and the tectonic paleogeography of the deposit，it’s thought that the Yangjiawan manganese deposit is located in the black water creek-Yangjiawan stretch in the direction of 65°70° in the early northeast of the Nanhuaji Datang Slope.Banded Class IV mantle basin.Combined with the bubble-like structure filled with asphalt and the structure of the leakage pipe，such as the bubble-like structure and the leakage pipe structure，the distribution characteristics of the ancient gas leakage sedimentary structure are found.The genetic type of the deposit is the same as that of the Songtao Datangpo manganese deposit，so it’s a typical ancient natural gas seepage sedimentary manganese deposits. |
