| 摘 要： | 黔东北地区的氧化锰矿床系风化矿床，按其成因可进一步分为残积矿床和淋积矿床两种。前者在区域上分布相对较广，是由原生菱锰矿床经次生风化而成，呈带状延伸；后者是由锰质对原矿层附近围岩淋滤加积而成。本文探讨了不同类型矿床的特征和分布规律，同时还对该区氧化锰矿的成矿机理、控矿因素和区域找矿方向作了粗浅分析。

| Abstract: | Oxide manganese deposits in east-northern Guizhou are of exotic weathering deposits, further may be subdivided into two kinds of the eluvial ore deposit and the leaching-accretion deposit by genesis. The former, distributed in broad area comparatively, is originated from the primary rhodochrosite of sub-weathering, and occurs as banded extension; the latter resulted from manganese materials effect the wall-rock near the primer ore layers with leaching-accretion action. The characteristic and distribution rules of various deposits are deliberated; in addition the analysis on ore-forming mechanisms, factors of mineralizing control, and regional prospecting orientation is carried out. |
