| 中文摘要: |
| 通过贵州镇远马坪地区金刚石调查评价工作，在施秉大坪寒武系下统杷榔组地层中新发现钾镁煌斑岩岩体两个；以其产出地层低，所含角砾成分复杂且砾径差异大，爆发特征明显区别于其他岩体，其中一岩体为“岩管”产出。该岩体的发现为区域金刚石找矿开拓了思路，拓展了纵向找矿空间。本文主要从新发现岩体的产出特征入手，结合其岩石矿物学特征，分析其具有的金刚石找矿意义。 |

| By the diamond investigation in Maping area of Zhenyuan，two lamproite rock mass were found in Balang formation of Lower Cambrian in Daping of Shibing the first time，it different from the other rock mass of the low strata，complex breccia composition，gravel diameter and obvious erupt features，one of them is tube occurrenceThe discovery of the rock mass will widen train thought and space for diamond exploration in this areaIn this paper, according to the occurrence features of the new rock mass，it found out the petrological features and thought that it has significance for diamond exploration |
