重庆市城口锰矿床地质特征及分层取样法的运用效果

The Geological Features of Cheng-Kou Mn-ore Deposit of Chongqing and Their Applying Result of Drawing Samples Layer upon Layer

简单介绍了区域地质背景,较详细地论述了城口锰矿床地质特征的基础上,着重探讨了锰矿层剖面结构特征、磷的赋存状态及分布规律,详细地介绍"分层取样法"的布样原则、新旧取样方法的对比以及该方法应用的范围、条件和运用效果。

This article makes a brief introduction of district geological background. It clearly discusses about the geological features of ChengKou Mn-ore deposit, and at the same time the author analyses the structural features of the section of Mn-ore layer, the storing situation of phosphorus and its distributing rules. The way of drawing samples layer upon layer and the way of drawing samples by comparison are both proposed with their appling scales, conditions and apply results.
