| 中文摘要: |
| 罗甸玉属于高档软玉，具有稀缺性和极高的经济价值，但其勘查评价方法受到矿体特殊产状和厚度薄的综合因素制约，不适用于固体矿产勘查工作规范。通过前期勘查实践和方法研究，新提出在勘查工作中以含矿体作为基本填图单元应用于图面表达具有显著的合理性和可操作性，在资源评价工作中采用系数调整法校正资源储量，可以解决软玉矿勘查评价难的问题，进而完善软玉矿的勘查评价体系。 |
| 英文摘要: |
| The Luodian nephrite belongs to high-grade nephrite. It has rare and high economic value. However, its exploration evaluation method does not suitable for the solid mineral exploration standard, due to be restricted by comprehensive factors as special occurrence and thin thickness of orebody. Based on early systematic exploration practice and method investigation, we propose that applying ore-bearing bodies as basic mapping units to geological map expression can be of significant rationality and maneuverability for working in field exploration, and that using coefficient adjustment method to correct resource reserves estimation in resource evaluation can resolve the difficulty in nephrite mineral exploration and evaluation and improve exploration evaluation system of the nephrite mineral resources. |
